[Ts Demuxer] No PES startcode

[lodger]

Hi,
from latest version of avidemux the TS manage is much better: in the older version audio went out of sync. But sometimes it still can't open some TS files:

mpv plays it perfectly but says some errors:

I use ArchLinux32:

Please retest with a build off the latest ffmpeg4x branch.

[lodger]

i tried again: after one minute of error avidemux was able to open it 

[eumagga0x2a]

Do you refer to a build off the current ffmpeg4x branch now?

[lodger]

Do you refer to a build off the current ffmpeg4x branch now?

no, i have used same configuration of first post.

[eumagga0x2a]

You're on Linux. It is trivial to build and run a current Avidemux (it is even doesn't need to be installed). Similar issues were reported and fixed a while ago.

[eumagga0x2a]

Avidemux built from the current git ffmpeg4x branch head opens the sample you provided just fine without any perceptible delay.

[lodger]

then it's a problem that has recently been solved. i use ffmpeg 1:4.0.2-2.4 and avidemux-qt 2.7.1-5.0.

[eumagga0x2a]

This is exactly what I try to explain. Unless affordable time travel becomes available, there is no way to fix bugs for users of past releases. Build Avidemux off the current git ffmpeg4x branch (not master!) yourself to get a better experience.

Just to avoid a misunderstanding: a few decoding errors are present because the video stream is not perfectly error-free (temporary problems with signal quality is the most probably cause), Avidemux can't do anything about it.

i have tried avidemux3 of ffmpeg4x git branch. indeed it open immediately this TS file without error!
