Hi TI experts,
First of all, thanks very much for TI exports giving me so much help before.
Lately, I study DM6467 MPEG4 encoder and decoder for h.263 because the item need.
The DM6467 MPEG4 encoder and decoder come from TI official website. the encoder version is 01.00.00.09 , the decoder version is 01.00.00.05.
So,I need to confirm the declare in the encoder and decoder userguide document because I encount some problems when I test the encoder and decoder.
First, I can get mpeg4 bitstream and h.263 bitstream by setting the MPEG4 encoder, but the MPEG4 decoder can decode the mpeg4 bitstream but not decode the h.263 bitstream.
Second, I use the third software play the h.263 bitstream and can find some information about the bitstteam. I can see the value of short_video_header In the VideoObjectLayer is 0. At the same time, the MPEG4 decoder userguide document declares that surport short video header h.263 and the value of short_video_header is 1 at this staus.
Third, I cann't find param about setting the value of short_video_header in MPEG4 encoder userguide document.
So, my first problem is whether the MPEG4 encoder can only encode un_short_video_header h.263 bitstream but not short_video_header h.263 bitstream.
And the second problem is whether the MPEG4 decoder can only decode short_video_header h.263 bitstream but not un_short_video_header h.263 bitstream.
Further more, my third problem is whether the MPEG4 decoder cann't decode the h.263 bitstream that generated from the MPEG4 encoder.
Hopefully you can give me some help.
