Hi, Not going to fly when your video source is a remote video phone - you can only decode the frames as they are received.
Also frames can only be encoded at the local end at whatever rate the camera supplies them at. We also have to account for any latency all the buffering causes, playback of non real time video material does not care so much about that - I suppose lip sync is still important though. The extra frames didn't make any difference that was worth keeping.

In order to gain something, you must be sure that after a period of heavy CPU load comes a period of low CPU load that allows you to refill your buffer queue. I doubt that this can be met with normal video content. Most "high action" scenes will last longer than your buffers anyway. _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
