[Live-devel] H264 SDP sprop_parameter_sets_str definition

[Ganesh V]

Hi Tao,


>From RFC 3984, (sprop-parameter-sets)

 The value of the parameter is the base64 [6] representation of the initial parameter set NAL units 
as specified in sections 7.3.2.1 and 7.3.2.2 of [1]
This refers to SPS and PPS in H.264 standard. This post shows the description of sprop_parameter_sets: http://lists.live555.com/pipermail/live-devel/2009-May/010602.html 

When SPS and PPS are used to generate the sprop_parameter_sets, their NALU start codes should be removed. 


Cheers,
Ganesh

Hi,

I write a H264 framer and it works with openRTSP. However, it will
cause VLC player to crash.
Thanks for Ross's comment, I realized that my setup of SDP
sprop_parameter_sets_str is not correct.

I do not know the format or structure of SDP sprop_parameter_sets. I
go over the RFC 3984, but not find the structure of it.
Can anyone point out where I can find its definition/structure?
Thanks a lot.

Tao
