Hello,

Normally a decoder will need SPS and PPS to get configured
properly. So your .264 should contains at least SPS+PPS
for VLC to be able to play it correctly. If not, it may be guessing
some parameters which is not very compliant.

When streaming using RTSP/RTP, you get SPS+PPS from the SDP
through the RTSP Session.
If you want a "stand-alone" stream, (itout RTSP nor SDP) such as
when doing MPEG TS, then SPS/PPS must be added before each 
IDR frame.

It is similar to Repeat Start of Sequence in MPEG-2.

Regards,

Jean-Michel.

  Hi,

  This may help you. 

  I can copy a .264 file from the DVEVM board to a pc and play it using 
VideoLan.

  When streaming we found this out:

  We are not using RTP,  but to get our player to play the .264 stream, we 
added the SPS (Sequence Parameter Set - 14 bytes) to each frame.  It seams that 
in a normal file it shows up once, if you miss this information nothing will 
play for the next farmes.

  There may be some one with a better way, but it works for us.

    Hi everybody,

    I want to do RTP application with DVEVM. 

    I must send data which encoded (*.264) to other pc and decode it. So i will 
transfer video real time.

    But i can't access encodedbuffer. when i create a file including encoded 
data with .264 extension, i don't decode it, i can't see anything.

    Have you got any info about this problem?
    Or how can i access to encoded data?

    Thanx
