[Mp4-tech] MPEG-4 video null P encoding

[Swapna Matwankar]

Hi veni,
If you are coding H.263 then you can have all the macroblocks as not coded (COD = 1). This will repeat the previous frame.
If you are coding an MPEG4 stream, then you can put a VOP header with VOP coded flag set to 0 in the bitstream.
regards,
swapna
