I do not know if you have encountered such a situation, such as video merging file names are not in the normal order, like this
As you can see, the file name sorting is messed up. This way the merged video must be messed up as well. So we have to find a way to modify the file name, so that the software read out the correct order. Without further ado, on the code.
"""
Note: i. Filenames minus extensions must end with '_' + number. ii.
II. Place in the Documents directory.
Third, there should be no redundant files in the directory
Main Algorithm:
Add 0 according to the number of digits of the largest number
For example, if the maximum number is 123, then the number of digits is 3.
1 will become 001, 2 will become 002, 23 will become 023, in that order...
"""
import os
li = []
new_li = [] # New filename
null_li = [] # Non-standardized file names
filenames = ('./')
# Get the maximum number of digits of a number
for filename in filenames:
tmp = (filename)[0] # Get the filename
if('_' in tmp): # Find the sign before the number
num = ('_')[-1]
(num)
else:
null_li.append(filename)
max_len = len(max(li, key=len))
# ~ print(max_len)
# New filename
for filename in filenames:
name = (filename)[:-1] # Get the filename
name = '_'.join(name)
ext = (filename)[-1] # Get the extension
if('_' in name): # Find the sign before the number
name1 = ('_')[:-1]
name1 = '_'.join(name1) # file name
num = ('_')[-1]
quantity = max_len - len(num)
name2 = '0' * quantity + num # Number Name
filename = name1 + '_' + name2 + ext
new_li.append(filename)
# ~ new_li.sort()
# ~ print(filenames)
# ~ print('\n')
# ~ print(new_li)
# Check for irregular file names
if(len(filenames)-1 != len(new_li)):
null_li.remove('')
null_li = '、'.join(null_li)
print("error: \""+ null_li + "\" does not end with '_' + number.")
exit()
# Modify the file name
i = 0
for oldname in filenames:
if (oldname != ''):
(oldname,new_li[i])
print(oldname,'======>',new_li[i])
i+=1
One of the caveats is also explained in the above code. After running successfully, check again the
As you can see, the videos are already in order.
