Hello,
Most probably your SPS and PPS-Headers are in the SDP-Information of
your RTSP-DESCRIBE-Response. Look RFC 3984 in section 8.2. for more
information.
Normally both Header are Base64-encryptet in the "sprop-parameter-sets".
jens.

Dear all,
I have two questions regarding openRTSP.
1. I have a H264 camera with built-in RTSP server (an IP camera) and I am using openRTSP to receive
the video stream. It works nice, I can receive frames of type IDR slices and other coded slices.
However, a standard H264 also contains a SPS (sequence parameter set) NAL unit followed by a PPS
(picture parameter set) NAL unit followed by the first IDR frame. The IP camera manufacturer
confirmed that they include the SPS+PPS "header bytes" before the very first IDR frame
and also before some later IDR frames at regular intervals. As I receive clean frames from live555
library without SPS+PPS I ust want to ask, if there is the possibility to somehow get these bytes,
because I want to save them before the start of the stream. I tested the incoming frames and the
first byte tells me, that the frames are clean IDR slices and other coded slices (NAL unit types 5
and 1). The SPS and PPS "header bytes" are missing.
2. Is there a way to set a custom timeout value for the RTSP client that the
client would use for each command like PLAY, TEARDOWN or OPTIONS? I would like
to be able to change the timeout and to force the RTSP client to complete a
method master when the RTSP server is unavailable. I searched the code and
found some timeout parameters, but I am not sure that I am doing the right
thing.
Thanks very much in advance
Alex
