[Live-devel] MPEG4 Encoder Headers

[Vitor Carvalho]

Hello...i need some help..

 That’s what i found:

MPEG4 Encoder Headers 

Some streaming applications, such as live555 ( <http://www.live555.com>
http://www.live555.com) require the following additional headers in the
MPEG4 stream: Visual Object Sequence Start (VOSS) and the Visual Object
Start (VOS) headers. 

VOSS = 000001B0 00000000; VOS = 000001B5 00000005 

These headers are not present in the stream generated by the DM355 encoder
because they are optional for elementary streams. (Note: these headers are
present in a stream generated by the DM6446 or DM6437 MPEG4 Encoder) 

If an application requires these headers, the application must add them to
the encoded stream in the following order: VOSS+VOS+EncodedStream. 

 

I´m using DM355 and trying to do video streaming to a Pc client with VLC. As
you know, live555 doesn’t support MPEG4 streaming, just m4e. So, i would
like to know how to implement this solution (add the VOSS and VOS
headers).More specific, what i have to add and where?! Hope that somebody
can help me..Thanks
