I'm trying to split some mpg files and there's no audio even if I just play the file. I don't know what I'm missing. This is Windows 10. Thank You.
Do you have VLC (http://www.videolan.org/vlc/) installed?
Load video into VLC and VLC -> Tools -> Codec Information
This should tell you if audio track is present:
here's what I see in VLC for the a file that doesn't have audio in Avidemux
it's just doing this on video I captured using Avermedia Media Center
A short chunk of the file would help
A few megs uploaded to mega for example
