Ok, can you tell me which pts of first frame?
I think you can decrease pts on first frame's pts instead 
m_stream-start_time.

[osg-users] [osgPlugins] ffmpeg plugin : big delay

2010-09-28 Thread Malek Baklouti 
Hey guys, 

I'm encountering a small issue related to ffmpeg plugin. I'm trying to acquire 
and show in real time video (RTSP) coming from an axis camera. 

The problem is that my video has a delay of around 5 seconds.. 

I did some tests using VLC, and by modifing the cache size I had realtime 
video..but I have no idea how to make that using osg ffmpeg plugin.

Does any one had to overcome this issue?

Thank you!

Cheers,
Malek

I'm wondering is there any relation with that instruction : 

line 231 in FFmpegDecoderVideo.cpp 
 packet = m_packets.timedPop(is_empty, 10);
 

what does the 10 stand for? 


thanks,
Malek
