Jitsi Videobridge H.264 frame format


I have Jitsi Videobridge working and tested with VP8, VP9 and H.264 codecs. So far so good. I was, however, expecting a different frame data format from the H.264 stream. VP8/9 produce frame data (as expected) in the raw format:

_rawVideoSource_OnRawVideoFrame(uint width, uint height, byte[] yPlane, uint yStride, byte[] vPlane, uint vStride, byte[] uPlane, uint uStride)

I was expecting a different format for the H.264 frames, namely:

_encodedVideoSource_OnEncodedVideoFrame(uint width, uint height, byte[] data).

The H.264 stream seems to be producing the first - Raw Video - frame format. Is this right?
