I'm working with the class H264VideoRTPSource when I recieve RTP
data information of an IP Camera and I have some questions.
First, If I look my (subsession->(fVideoWidth y fVideoHeight)) and I
can't extract video resolution because this values are 0.
Only a few RTSP/RTP streams specify this information in their SDP
description (i.e., as a hint). In general, you can get this
information (video width and height) only by decoding the video
stream.
Then I'm looking to extract that information looking the SPS,
Sequence Parameter Set, packets. On the live555 classes I have been
looking and I can't find any parser of that data. Is possible
extract that information using live555 or I need to search another
parser to do that task?
No, you will need a H.264 video decoder.
