Guide to using WMP video control in web pages
□Playing methods and properties
In addition to playing, pausing, and stopping, the media player also has the following properties:
Scanning—similar to the fast forward and fast inversion function of the video recorder;
Searching - Move directly to the specific stage time marked in the clip;
□Play
Media player provides two techniques to specify the media name (clip) to be played. You can set the FileName property, or call the Open method. If the value of the AutoStart property is true, the movie clip will start playing when the FileName property is set to the URL of the movie clip; otherwise the movie clip will not start playing unless you call the Play method. The Open method starts playing asynchronously, unlike the Play method, which does not start playing until other processes are finished.
The media player provides the following VCR-like properties and methods to control streaming media playback:
Play, Stop, Pause methods to start, stop, and pause streaming.
PlayCount property, sets the number of times the file is played.
AutoRewind property, determines whether to return to the beginning of the movie clip when the playback is stopped.
□Audio control
The media player provides the following properties to manage audio:
Balance attribute, determines the sound balance between left and right speakers;
Volume attribute, used to increase or decrease the volume;
Mute property, used to turn off or turn on sound;
※You can set the ShowAudioControls property to true to add controls to the control bar to process sounds.
□Scan
The media player provides the following properties for scanning:
FastForward method, fast forward;
FastReverse method, quickly turn it down;
Rate attribute, change the playback rate;
※To make movie clips scanned, the CanScan and AllowScan properties must be set to true.
□Search
The attributes used for search are:
MarkerCount property, refers to the total number of markers in the clip;
CurrentMaker, GetMarkerName, GetMarkerTime methods are used to return tag information;
MarkerHit event, triggered when a marker is encountered;
CurrentPosition property, the current position (measured in seconds), can be used to move the playhead to the specified point in the clip;
PositionChange event, triggered when the CurrentPosition property is set;
※To search for any time, the CanSeek attribute must be set to true. To search for marking points, the CanSeekToMarkers attribute must be set to true.
□Appearance interface of media player
In a web page, you can control which parts of the media player appear and which parts do not appear through relevant properties.
The media player includes the following elements:
Video Display Panel: Video Display Panel;
Video Border: Video border;
Closed Captioning Display Panel; subtitle display panel;
Track Bar; Search Bar;
Control Bar with Audio and Position Controls: Control bar with sound and position control;
Go To Bar: Go to the bar;
Display Panel: Display panel;
Status Bar: Status Bar;
The following attributes are used to determine which element to display:
ShowControls property: Whether to display the control bar (including playback controls and optional sound and position controls);
ShowAudioControls Properties: Whether to display sound controls (mute buttons and volume sliders) in the control bar;
ShowPositionControls property: Whether to display position controls in the control bar (including jump backward, rewind, fast forward, jump forward, preview each clip in the playlist);
ShowTracker property: Whether to display the search bar;
ShowDisplay attribute: Whether to display the display panel (used to provide information about programs and clips);
ShowCaptioning property: Whether to display the subtitle display panel;
ShowGotoBar property: whether to display Go to the bar;
ShowStatusBar property: Whether to display the status bar;
□Play list
The media player provides the following methods to access clips in a playlist:
Next method, skip to the next clip in the show (playlist);
Previous method, jump back to the previous clip in the show;
A feature of the media player is that it can preview every clip in the program, using the following properties:
PreviewMode property determines whether the media player is currently in preview mode;
CanPreview attribute determines whether the media player can be in preview mode;
In the windows media metafile, you can specify a preview time - PREVIEWDURATION for each clip. If not specified, the default preview time is 10 seconds.
You can also use Windows media metafiles to add watermarks and banners, and the metafiles also support gapless stream switching when inserting ads.
□Program information
Use the GetMediaInfoString method to return the following information about the relevant clip or program:
File name: File name
Title
Description: Description
Author: Author
Copyright: Copyright
Level: Rating
URLs: address of logo icon, watermark, banner
Clip information can be placed in media files, in Windows media metafiles, or both. If clip information is specified in the metafile, the information in the metafile is returned by the GetMediaInfoString method, and the information contained in the clip will not be returned.
In metafiles, additional information can be placed in the PARAM tag of each clip or program. You can add as many PARAM tags to each clip to store custom information or link to related sites. Information in the PARAM tag can be accessed through the GetMediaParameter method.
The following properties return information about size and time:
ImageSourceHeight, ImageSourceWidth: Returns the display size of the image window;
Duration property, returns the length of the clip (seconds). To check whether this property contains a valid value, check the IsDurationValid property. (For broadcast videos, the length is unpredictable).
□Subtitles
You can use the .smi file to add subtitles to your show. The media player supports the following properties to handle subtitles:
SAMIFileName property, specifying the name of the .smi file;
SAMILang property, specifying the language for the subtitles (if not specified, the first language is used);
SAMIStyle property, specifying the text size and style of the subtitles;
ShowCaptioning property, determines whether to display the subtitle display panel;
□Script command
With audio and video streams, you can add script commands to the streaming media file. Script commands are multiple pairs of Unicode strings in a multimedia stream that are synchronized with a specific time. The first string identifies the type of command to be sent, and the second string specifies the command to be executed.
When the stream is played to a script-related time, the control sends a ScriptCommand event to the web page, and the event handler responds to the event. The script command string is passed to the event handler as a parameter to the script command event.
The media player will automatically process the following types of embedded script commands:
1) URL type command: When the media player control receives a URL type command, the specified URL will be loaded into the user's default browser. If the media player is embedded in a framed HTML file, the URL page can be loaded into the frame specified by the script command. If the script command does not specify a frame, the DefaultFrame property will determine which frame the URL page will be loaded.
You can decide whether to automatically process URL-type script commands by setting the InvokeURLs property. If the value of this property is false , the media player control ignores the URL-type command. But script command events still fire, which allows you to selectively handle URL-type commands.
The URL type command specifies the relative address of the URL. The base address is specified by the BaseURL attribute. The command parameters of the script command event transmitted by the media player control are the linking address.
2) FILENAME type command: When the media player control receives a FILENAME type command, it sets the FileName property to the file provided by the script command, and the media player will open the file and start playing. Media player controls always process FILENAME type commands automatically, unlike URL type commands, they cannot be prohibited.
3) TEXT type command: When the media player control receives a TEXT type command, it will display the content of the command in the control's subtitle window. The content can be plain text or HTML.
4) EVENT type command: When the media player control receives an EVENT type command, it will search the media metafile for the NAME attribute of the EVENT element. If the NAME attribute matches the second string in the script command, the media player control executes the entry contained in the EVENT element.
5) OPENEVENT type command: When the media player control receives an OPENEVENT type command, it checks the EVENT element in the media metafile and opens the matching title, but does not play until it receives a real event of the same name from the EVENT type command.
□Capture keyboard and mouse events
The EnableContextMenu and ClickToPlay properties provide users with a method to operate in the image window.
If the EnableContextMenu property is true, right-clicking the mouse in the image window can open the context menu. If the ClickToPlay property is set to true, the user can click the image window to switch between playback and pause.
To receive mouse movement and click events, set the SendMouseMoveEvents and SendMouseClickEvents properties to true . Mouse events include:
MouseDown, generated when the user presses the mouse;
MouseUp, generated when the user releases the mouse;
MouseMove, generated when the user moves the mouse;
Click, generated when the user clicks the mouse button on the media player;
DbClick, generated when the user double-clicks the mouse button on the media player;
To receive keyboard events, set the SendKeyboardEvents property to true . Keyboard events include:
KeyDown, generated when the user presses a key;
KeyUp, generated when the user releases a key;
KeyPress, generated when the user presses and releases a key;
□ Monitor flow status and network links
Flow state properties include:
PlayState: playback status;
OpenState: Open status;
Bandwidth: bandwidth;
Supported events are:
OpenStateChange: Open state change (fired only if the SendOpenStateChangeEvents property is true)
PlayStateChange: Play status changes (only triggered when the SendPlayStateChangeEvents property is true)
EndOfStream: Triggered at the end of the stream;
NewStream: Triggered when opening a new stream;
Network reception attributes include:
ReceptionQuality: Receive quality;
ReceivedPackets: packages that have been received;
LostPackets: Lost packages;
The properties of monitoring buffers are:
BufferingTime: Buffering time;
BufferingCount: the number of buffers;
BufferingProgress: buffering process;
Buffering: buffering events;
□Error handling
Media players provide built-in error handling capabilities—display error messages in the dialog box or status bar. Also, you can add an error handler yourself. If the SendErrorEvents property is set to true, an error box will not be displayed, but an error event will be sent; if the SendErrorEvents property is set to false, an error box will be displayed, but an error event will be sent.
The media player supports the following error handling events:
Error Event, refers to a dangerous error;
Warning incident refers to a non-risk error;
When your application receives an error event, you can detect the following properties to determine the specific error message:
HasError: Detect the current media player for errors;
ErrorCode: Provides code values related to errors in this type;
ErrorDescription: Provides error description information;
ErrorCorrection: Specifies that the media player corrects this type of error;
□Play CD
The media player treats the CD as a single audio stream (with markers at the beginning of each track). To use CDs in web pages, you need to set the FileName property to CDAUDI, which must be with a colon as shown below:
<HTML>
<HEAD><TITLE>CD Audio Playback Example</TITLE></HEAD>
<BODY>
<OBJECT ID="MediaPlayer"
CLASSID="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95"
WIDTH="320"
HEIGHT="508"
STYLE="position:absolute; left:0px; top:70px;" >
<PARAM NAME="FileName" VALUE="cdaudi">
<PARAM NAME="AutoStart" VALUE="0">
<PARAM NAME="ShowControls" VALUE="1">
<PARAM NAME="ShowStatusBar" VALUE="1">
<PARAM NAME="ShowDisplay" VALUE="1">
</OBJECT>
</BODY>
</HTML>
After that, you can use the Play method to play the CD.
You can specify the playback order and information for each track in the Windows media metafile. Examples are as follows:

1. How to paste rm, ra, ram type music, the code is as follows:
<embed width="0" height="0" type="audio/x-pn-realaudio-plugin" autostart="true" controls="ControlPanel" src="/uploads/";>
2. How to paste music of midi, asf, wma, asx, the code is as follows:
<embed autostart="true" loop="-1" controls="ControlPanel" width="0" height="0" src="/uploads/";>
3.<bgsound src="Your Song Address" loop="-1">
You only need to copy the entire code into the article (please use HTML code mode when editing the article, otherwise the code will be displayed in text form and cannot be executed), and use the URL of your favorite music file to replace the above music address code. Note that if the music is too large, it may cause the browser to stop responding if it is serious. Therefore, if you want to play background music, please do not use large files.
The URL of a music file refers to the URL of the music file.
The way to get the URL is to move the mouse to the link music name and right-click -> Copy shortcut, and then press CTRL+C to the URL where you want to add the music file (paste the previously copied address).
There are two errors in this case where you cannot listen to music normally after adding background music:
1. The music address is wrong, and the URL ending at html is mistakenly regarded as the address of the music.
2. The music file is too large and it takes a long time to play.

There are almost so many commonly used ones. For all information, please refer to the Windows Media Player 9 SDK documentation.
There is also an attribute: the number of the current media in the current playlist, and I don’t know how to get it. I hope friends who know will leave a message to let me know, thank you.

Guide to using WMP video control in web pages
□Playing methods and properties
In addition to playing, pausing, and stopping, the media player also has the following properties:
Scanning—similar to the fast forward and fast inversion function of the video recorder;
Searching - Move directly to the specific stage time marked in the clip;
□Play
Media player provides two techniques to specify the media name (clip) to be played. You can set the FileName property, or call the Open method. If the value of the AutoStart property is true, the movie clip will start playing when the FileName property is set to the URL of the movie clip; otherwise the movie clip will not start playing unless you call the Play method. The Open method starts playing asynchronously, unlike the Play method, which does not start playing until other processes are finished.
The media player provides the following VCR-like properties and methods to control streaming media playback:
Play, Stop, Pause methods to start, stop, and pause streaming.
PlayCount property, sets the number of times the file is played.
AutoRewind property, determines whether to return to the beginning of the movie clip when the playback is stopped.
□Audio control
The media player provides the following properties to manage audio:
Balance attribute, determines the sound balance between left and right speakers;
Volume attribute, used to increase or decrease the volume;
Mute property, used to turn off or turn on sound;
※You can set the ShowAudioControls property to true to add controls to the control bar to process sounds.
□Scan
The media player provides the following properties for scanning:
FastForward method, fast forward;
FastReverse method, quickly turn it down;
Rate attribute, change the playback rate;
※To make movie clips scanned, the CanScan and AllowScan properties must be set to true.
□Search
The attributes used for search are:
MarkerCount property, refers to the total number of markers in the clip;
CurrentMaker, GetMarkerName, GetMarkerTime methods are used to return tag information;
MarkerHit event, triggered when a marker is encountered;
CurrentPosition property, the current position (measured in seconds), can be used to move the playhead to the specified point in the clip;
PositionChange event, triggered when the CurrentPosition property is set;
※To search for any time, the CanSeek attribute must be set to true. To search for marking points, the CanSeekToMarkers attribute must be set to true.
□Appearance interface of media player
In a web page, you can control which parts of the media player appear and which parts do not appear through relevant properties.
The media player includes the following elements:
Video Display Panel: Video Display Panel;
Video Border: Video border;
Closed Captioning Display Panel; subtitle display panel;
Track Bar; Search Bar;
Control Bar with Audio and Position Controls: Control bar with sound and position control;
Go To Bar: Go to the bar;
Display Panel: Display panel;
Status Bar: Status Bar;
The following attributes are used to determine which element to display:
ShowControls property: Whether to display the control bar (including playback controls and optional sound and position controls);
ShowAudioControls Properties: Whether to display sound controls (mute buttons and volume sliders) in the control bar;
ShowPositionControls property: Whether to display position controls in the control bar (including jump backward, rewind, fast forward, jump forward, preview each clip in the playlist);
ShowTracker property: Whether to display the search bar;
ShowDisplay attribute: Whether to display the display panel (used to provide information about programs and clips);
ShowCaptioning property: Whether to display the subtitle display panel;
ShowGotoBar property: whether to display Go to the bar;
ShowStatusBar property: Whether to display the status bar;
□Play list
The media player provides the following methods to access clips in a playlist:
Next method, skip to the next clip in the show (playlist);
Previous method, jump back to the previous clip in the show;
A feature of the media player is that it can preview every clip in the program, using the following properties:
PreviewMode property determines whether the media player is currently in preview mode;
CanPreview attribute determines whether the media player can be in preview mode;
In the windows media metafile, you can specify a preview time - PREVIEWDURATION for each clip. If not specified, the default preview time is 10 seconds.
You can also use Windows media metafiles to add watermarks and banners, and the metafiles also support gapless stream switching when inserting ads.
□Program information
Use the GetMediaInfoString method to return the following information about the relevant clip or program:
File name: File name
Title
Description: Description
Author: Author
Copyright: Copyright
Level: Rating
URLs: address of logo icon, watermark, banner
Clip information can be placed in media files, in Windows media metafiles, or both. If clip information is specified in the metafile, the information in the metafile is returned by the GetMediaInfoString method, and the information contained in the clip will not be returned.
In metafiles, additional information can be placed in the PARAM tag of each clip or program. You can add as many PARAM tags to each clip to store custom information or link to related sites. Information in the PARAM tag can be accessed through the GetMediaParameter method.
The following properties return information about size and time:
ImageSourceHeight, ImageSourceWidth: Returns the display size of the image window;
Duration property, returns the length of the clip (seconds). To check whether this property contains a valid value, check the IsDurationValid property. (For broadcast videos, the length is unpredictable).
□Subtitles
You can use the .smi file to add subtitles to your show. The media player supports the following properties to handle subtitles:
SAMIFileName property, specifying the name of the .smi file;
SAMILang property, specifying the language for the subtitles (if not specified, the first language is used);
SAMIStyle property, specifying the text size and style of the subtitles;
ShowCaptioning property, determines whether to display the subtitle display panel;
□Script command
With audio and video streams, you can add script commands to the streaming media file. Script commands are multiple pairs of Unicode strings in a multimedia stream that are synchronized with a specific time. The first string identifies the type of command to be sent, and the second string specifies the command to be executed.
When the stream is played to a script-related time, the control sends a ScriptCommand event to the web page, and the event handler responds to the event. The script command string is passed to the event handler as a parameter to the script command event.
The media player will automatically process the following types of embedded script commands:
1) URL type command: When the media player control receives a URL type command, the specified URL will be loaded into the user's default browser. If the media player is embedded in a framed HTML file, the URL page can be loaded into the frame specified by the script command. If the script command does not specify a frame, the DefaultFrame property will determine which frame the URL page will be loaded.
You can decide whether to automatically process URL-type script commands by setting the InvokeURLs property. If the value of this property is false , the media player control ignores the URL-type command. But script command events still fire, which allows you to selectively handle URL-type commands.
The URL type command specifies the relative address of the URL. The base address is specified by the BaseURL attribute. The command parameters of the script command event transmitted by the media player control are the linking address.
2) FILENAME type command: When the media player control receives a FILENAME type command, it sets the FileName property to the file provided by the script command, and the media player will open the file and start playing. Media player controls always process FILENAME type commands automatically, unlike URL type commands, they cannot be prohibited.
3) TEXT type command: When the media player control receives a TEXT type command, it will display the content of the command in the control's subtitle window. The content can be plain text or HTML.
4) EVENT type command: When the media player control receives an EVENT type command, it will search the media metafile for the NAME attribute of the EVENT element. If the NAME attribute matches the second string in the script command, the media player control executes the entry contained in the EVENT element.
5) OPENEVENT type command: When the media player control receives an OPENEVENT type command, it checks the EVENT element in the media metafile and opens the matching title, but does not play until it receives a real event of the same name from the EVENT type command.
□Capture keyboard and mouse events
The EnableContextMenu and ClickToPlay properties provide users with a method to operate in the image window.
If the EnableContextMenu property is true, right-clicking the mouse in the image window can open the context menu. If the ClickToPlay property is set to true, the user can click the image window to switch between playback and pause.
To receive mouse movement and click events, set the SendMouseMoveEvents and SendMouseClickEvents properties to true . Mouse events include:
MouseDown, generated when the user presses the mouse;
MouseUp, generated when the user releases the mouse;
MouseMove, generated when the user moves the mouse;
Click, generated when the user clicks the mouse button on the media player;
DbClick, generated when the user double-clicks the mouse button on the media player;
To receive keyboard events, set the SendKeyboardEvents property to true . Keyboard events include:
KeyDown, generated when the user presses a key;
KeyUp, generated when the user releases a key;
KeyPress, generated when the user presses and releases a key;
□ Monitor flow status and network links
Flow state properties include:
PlayState: playback status;
OpenState: Open status;
Bandwidth: bandwidth;
Supported events are:
OpenStateChange: Open state change (fired only if the SendOpenStateChangeEvents property is true)
PlayStateChange: Play status changes (only triggered when the SendPlayStateChangeEvents property is true)
EndOfStream: Triggered at the end of the stream;
NewStream: Triggered when opening a new stream;
Network reception attributes include:
ReceptionQuality: Receive quality;
ReceivedPackets: packages that have been received;
LostPackets: Lost packages;
The properties of monitoring buffers are:
BufferingTime: Buffering time;
BufferingCount: the number of buffers;
BufferingProgress: buffering process;
Buffering: buffering events;
□Error handling
Media players provide built-in error handling capabilities—display error messages in the dialog box or status bar. Also, you can add an error handler yourself. If the SendErrorEvents property is set to true, an error box will not be displayed, but an error event will be sent; if the SendErrorEvents property is set to false, an error box will be displayed, but an error event will be sent.
The media player supports the following error handling events:
Error Event, refers to a dangerous error;
Warning incident refers to a non-risk error;
When your application receives an error event, you can detect the following properties to determine the specific error message:
HasError: Detect the current media player for errors;
ErrorCode: Provides code values related to errors in this type;
ErrorDescription: Provides error description information;
ErrorCorrection: Specifies that the media player corrects this type of error;
□Play CD
The media player treats the CD as a single audio stream (with markers at the beginning of each track). To use CDs in web pages, you need to set the FileName property to CDAUDI, which must be with a colon as shown below:
<HTML>
<HEAD><TITLE>CD Audio Playback Example</TITLE></HEAD>
<BODY>
<OBJECT ID="MediaPlayer"
CLASSID="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95"
WIDTH="320"
HEIGHT="508"
STYLE="position:absolute; left:0px; top:70px;" >
<PARAM NAME="FileName" VALUE="cdaudi">
<PARAM NAME="AutoStart" VALUE="0">
<PARAM NAME="ShowControls" VALUE="1">
<PARAM NAME="ShowStatusBar" VALUE="1">
<PARAM NAME="ShowDisplay" VALUE="1">
</OBJECT>
</BODY>
</HTML>
After that, you can use the Play method to play the CD.
You can specify the playback order and information for each track in the Windows media metafile. Examples are as follows:

1. How to paste rm, ra, ram type music, the code is as follows:
<embed width="0" height="0" type="audio/x-pn-realaudio-plugin" autostart="true" controls="ControlPanel" src="/uploads/";>
2. How to paste music of midi, asf, wma, asx, the code is as follows:
<embed autostart="true" loop="-1" controls="ControlPanel" width="0" height="0" src="/uploads/";>
3.<bgsound src="Your Song Address" loop="-1">
You only need to copy the entire code into the article (please use HTML code mode when editing the article, otherwise the code will be displayed in text form and cannot be executed), and use the URL of your favorite music file to replace the above music address code. Note that if the music is too large, it may cause the browser to stop responding if it is serious. Therefore, if you want to play background music, please do not use large files.
The URL of a music file refers to the URL of the music file.
The way to get the URL is to move the mouse to the link music name and right-click -> Copy shortcut, and then press CTRL+C to the URL where you want to add the music file (paste the previously copied address).
There are two errors in this case where you cannot listen to music normally after adding background music:
1. The music address is wrong, and the URL ending at html is mistakenly regarded as the address of the music.
2. The music file is too large and it takes a long time to play.

Common properties and methods of windows mediaplayer control
The windows mediaplayer control is often used when we program, but there are many properties and methods but I don’t know how to use it. Now, take the wmp 9.0 control as an example to talk about its commonly used properties and methods in Delphi 7.0 (the usage in JavaScript is almost exactly the same).
Assume that this control is named wmp

There are almost so many commonly used ones. For all information, please refer to the Windows Media Player 9 SDK documentation.
There is also an attribute: the number of the current media in the current playlist, and I don’t know how to get it. I hope friends who know will leave a message to let me know, thank you.
