#40 Crash with TS file

[FM33]

Hello,

With avidemux 2.6.8 x64 on Ubuntu 14.04 I have a crash on opening a TS file :

Assert failed :nalSize+16 at line 30, file /build/avidemux2.6-iCxcSA/avidemux2.6-2.6.8/avidemux_plugins/ADM_demuxers/MpegTS/ADM_tsIndexH264.cppADM_backTrack

Reproduced with another one, crashing at the half, no matter if there is a cut point or not, and the muxer (mp4v2 and mkv) :

I run into this bug very often. Is there anything I can do to help? I can provide some (unfortunately quite large) MPEG TS files to reproduce the bug.

[Mean]

yes, that would help

OK, I finally found the time to find a small enough file to add here. It is a plain recording from mythtv. As you can see, the file itself has some audio/video problems but this should not crash avidemux. It would be better if avidemux would skip or mark these broken parts instead.
