you copy MP2, stereo 256kbps track 0, and end up with (MP2, Stereo, 128kbps) in track 0, this is odd when copy is used Quote from: Jan Gruuthuse on November 18, 2015, 07:18:09 AM So it seems as if although track 1 is shown as selected when starting the video there is actually no default/active audio track in the mp4, so the MP2 track only gets activated if I actively select it. I start the video - no sound - go to the audio track selection dialog - track 1 is selected - I switch to track 2 - I get sound - BUT: now I switch back to track 1 - I also hear sound The TV does play the audio track - that is the irritating part: If I switch to the MP2 track, it is played, Gruuthuse When I switch the tracks AC3 first, MP2 second and play the video on the TV, it has sound right away. We could have a a cut with MP2, Stereo, 256kbps only: TV did not play any soundĪnother with AC3, Stereo, 448kbps only: TV did play sound If you can upload a 10 second mpeg-ts recording to a freely accessible web service (like dropbox) no login/registration. Is this from a satellite channel (FTA/ Europe / 28.2 23.5 19.2 east)? I could have a look. What would indicate you did not select the prime MP2 audio. sometimes one of the audio tracks is for the visually impaired or other language and is not available on transmission.

I have to switch to the 2nd and back so I can hear track 1 (but no problem when playing in VLC). ts files, in some cases the resulting mp4 does not play the first audiotrack when watched on the TV.
