[Libav-user] h263 frame rate

[David Longest]

Hello all,

I am demuxing an h263 RTP stream and providing the raw h263 data to libav. The source of the stream is transmitting at 15fps. It seems no matter what I do, libavcodec and libavformat give me back a framerate and time stamp that results in ~30fps. I have tried adding the option "framerate", "1:15" to the dictionary sent in avformat_open_input(), but it does not change the result. The incorrect framerate and AVStream time_base cause my playback to stutter.

What is the proper way to handle overriding the frame rate reported by libav?

Thanks,
David
