[Libav-user] Live video decoding with h264_mmal decoder
I am trying to decode a live h264 stream on a raspberry Pi. I have built ffmpeg with the latest git head, and configured it to run the h264_mmal decoder. However, if I feed it with a live stream at 1280x720p50 it says it's receiving 1280x720p23.98. If I do the same with the standard h264 codec rather than the h264_mmal codec then it finds the frame rate correctly. Is there anything in the mmal codec that would stop it finding the frame rate?
I know the example below is using ffmpeg, not the libav libraries, but the ultimate goal is to use the libav libraries, but running ffmpeg is just a quicker way of testing initially.
