Synopsis: Adding support for H.264 in AVI file format

 

Overview: This change enables playback of H.264 video inside an AVI file. There is no \
AVC Decoder Configuration Record found in such type of files and the Sequence \
Parameter Set (SPS) and Picture Parameter Set (PPS) are within the frames. However \
this means that we do not have the NALUSizeField available and we have to compute the \
appropriate number of bytes for decoding differently.
