MKV + H264 => libvlc looping sections.

Postby Diamant » 30 Nov 2014 16:06

Hi
I am developing libvlc based video player. Everything is fine except one strange problem...
If a video file is MKV H264 and it has sections it plays up to some point(s) jumps back few minutes before and does it again and again (loop)...
Strange, I tried to play same file(s) using the player itself (using default settings), they were fine but if I did the same using the libvlc libraries (code sample: https://wiki.videolan.org/LibVLC_Tutorial) video looped every time in the same points.
I have heard that there might be a problem with chapter like this one: https://forum.videolan.org/viewtopic.ph ... kv#p294193 but if I changed VLC player setting the problem did not appear in VLC player. When I changed the chapter settings in code - nothing happened (looping every time). What could I do?

This is the log (exactly in the moment of rewind):

Btw, there are no messages like spudecoder error while plainig the same video(s) directly in VLC player.
Please help :!:

Btw, Same behavior on VLC 2.1.0 and 2.1.5

Some update...

this:
spudec decoder debug: invalid starting packet (size < 4 or pts <=0)
[1444a694] spudec decoder debug: invalid starting packet (size < 4 or pts <=0)

is a result of incorrect sub picture data - disabling subtitles this message disappeared.

Now it looks like a jump from 16% to 15%. Completely unclear!
