[Live-devel] Video Delay in Live Video Streaming

[Abhishek Madaan]

Hi Ross,
              I able to solve the delay issue. It is not related to your library. I was not allocating the buffer correctly. It is all working now. I appreciate all the help you provided me.
 
Regards,

First, you should instead consider using the existing (open source) VLC media player <http://www.videolan.org/vlc/>, which also uses our libraries for its RTSP client implementation.

The increasing delay that you are seeing is unlikely to be due to a problem with our libraries.

One possible cause is that your computer doesn't have enough CPU power to handle the video decoding and rendering (as well as the RTSP/RTP reception, which has relatively little overhead).  One way to test this hypothesis is to try running VLC instead.

Another possibility is that you are not using the 'presentation times' for each received video frame (in this case, H.264 'NAL units') correctly.  Each frame's "presentation time" tells you the relative time at which each frame should be displayed (after decoding).


But in any case, because you are a casual hobbyist, I suggest just using VLC.
