Thank you for all of your input. Unfortunately I did not write the decoders at all, but I do have the source code. What is considered as decoder latency? Is it the time for decoder to set up or something else?

Any idea why > would h264 get stuck? </div> To start off, try setting max-size-time/bytes/buffers=0 on the both the queues (no limits) If it works, it indicates that your h264dec has a very high latency..and you can narrow to the problem from here. <div class="im"> > Another question is if I am giving too much memory to gstreamer with > max-size-time=0 max-size-bytes=0? </div> Well, It would depend on your codec details (resilution, etc), environment/platform. You could possibly track down the issue. <div><div></div><div class="h5"> > Cheers > Ogi > > > On Wed, Dec 8, 2010 at 8:27 PM, ved kpl <<a href="mailto:ved.kpl@gmail.com">ved.kpl@gmail.com</a>> wrote: >> >> Hi, >> >> One possible reason could be that one of the queues is getting full >> while the other remains empty >> because of >> (a) continuous audio/video buffers for a considerably longer time, >> longer than the what the queues can hold. >> (b) high latency at the your video decoder (mpeg4dec). >> Hence the streaming thread is blocked & one of the sinks is not able >> to commit the state to PAUSED. >> (because it has not received a buffer yet). >> >> Yo can also set async=FALSE on the sinks and see.
