remux_audio is not working

[jinlee487]

Hello,

I am calling remux _audio=True and I keep getting an error. It is weird, because the file downloads but just doesnt perform the remux conversion in the end.
I know remux is the problem because the code worked without it before and also when I pass it as False instead of True.
I downloaded ffmpeg btw.
Anyone know the solution to this issue?

I think I have identified the problem. I am not installing ffmpeg correctly. Is there any hint to installing ffmpeg correctly to use with pafy? I just used pip to install ffmpeg and ffmpeg-python but it still does not work :(

Well this is quite unfortunate. I have successfully installed ffmpeg and added it to PATH. ffmpeg -version in powershell works as it should. However I still am getting the same error...

[jinlee487]

CurrentFileName = 'TEST.m4a'
FinalFileName = 'TEST.mp3'
print(f'{CurrentFileName}')
print(f'{FinalFileName}')

try:
    subprocess.call(['ffmpeg', '-i', f'{CurrentFileName}', f'{FinalFileName}'])

except Exception as e:
    print(e)
    print('Error While Converting Audio')

ch = input('Press Enter to Close')```

this is the test file I ran to check if ffmpeg was working normally. To my surprise, it works fine. Now I am guessing there is an issue with pafy.

pafy/pafy/backend_shared.py

Line 719 in 5903c16

cmd = [tool, "-y", "-i", infile, "-acodec", "copy", "-vn", outfile]

I am wondering if this call does not work anymore? I tried running a similar line of code as a test subprocess. There was not any error raised, but the file output was empty.
