<div dir="ltr">Hi,<div><br></div><div>I'm currently working on integrating an old (highly customized) video server that my company has. </div><div>The old player was a custom built player as well, and the player and server were pretty much built one around the other.</div>
<div>Now trying to integrate it with VLC, I see a lot of problems (particularly after a seek - since at that point everything seems to go out of sync).</div><div><br></div><div>Sometimes (not always), after a seek the movie freezes - and when we use VLCJ to play it, the time change callback shows the time is not changing (but new packets are received).</div>
<div>I have checked the rtp timestamps and have tried altering them many times, but nothing seems to work (actually the times in the callback are unaffected) - which implies the problem lies within the mpeg packets (pts?).</div>
<div><br></div><div>I have looked at the times of the mpeg4 packets being released from the server (as an FFmpeg AVPacket) - pts, coded_picture_number, display_picture_number. The things I have noticed are that:</div><div>
1) pts cycles through the values 2-29 (in increments of 3) and repeats.</div><div>2) decoded_picture_number is incremented by 1 each packet</div><div>3) display_picture_number is a constant 0</div><div><br></div><div>I have two questions:</div>
<div>1) Does anyone know what the problem could be, or why the values are problematic for VLC?</div><div>2) What value does VLC use to determine the movie time? pts, decoded_picture_number, display_picture_number? A combination of the values? Some other values?</div>
<div><br></div><div>Thanks,</div><div> Tomer</div></div>
