MFC (MULTI FORMAT CODEC)
H.263 Case
In case of H.263, there is no sequence header and there is only frame header so the stream format is as following
figure.
Except for the first frame, the Host sets the FRAME_START to decode a frame and checks the
OPERATION_DONE. In case of the first frame, the Host sets the SEQUENCE_START to decode stream header
and checks the HEADER_DONE and then the Host sets the FRAME_START to decode a frame and checks the
OPERATION_DONE. Because there is no Stream header in the H.263, for the first frame, the Host sets the same
Stream Buffer configuration twice. The first configuration is for the Stream Header and the second configuration is
for the frame data.
