I work with aintel P4 and windows 2000.Is it possible to encode and decode Mpeg4 stream wihtout using avi file ? I want to use this codec for video conferencing application.

Hello, you probably can use UMC muxer component to pack payload data from your stream to MP4. I think if you first extract raw video stream from your RTP stream then you can mux it to MP4. Please look at MPEG4 standard for details about MP4 file format

Hi!

Vladimir, you mentioned that we have to change in VideoData.cpp the ALIGN_VALUE from 128 to 1. What are the effects of this parameter? I convert YV12 to RGB24 with my program but everything looks good. Sometimes I have a few badly decoded(or converted) frame, but I thougt it is the mpeg4 camera's fault. Do I have to change that parameter too?

Thanks in advance,

Bendeguy

Yes, according our experts, it is better to change for IPP 5.1.1 sample. Setting this to 1 you turn off alignment of VideoData's color planes pitches.

Hi Raj,

We are trying to do a similar thing (i.e. view a Bosch VideoJet 10 stream with a standard MPEG-4 viewer), but with no success.

Just wondering if you had had any success at your end? Send me an email, maybe we can help each other out?
