video doesn't have sound after re-encoding

[Nater]

I recorded a video from the livestream. I wanna share it with my friends who didn't watch it and now I have a problem. It's the second time when I captured stream with rtmpdump helper and this problem still happens. Video plays properly only in some software like PotPlayer or VLC, but when I try to edit it (cut out the adverts or change the resolution) the output file loses audio ( I got only video without sound), or the audio and video are out of sync with each other or video is without sound and looks like in slow motion. I'm using Vdub or Handbrake and tested many progs for converting files. Is it any possibility to get the correct video file? Avidemux doesn't work for me ;/

Are we supposed to guess at what video and audio codecs are used in this video file that you cannot edit and only plays in a few players?
