Hi all.
I am trying to receive video over RTSP and store it to disk using
GStreamer.
I have already added some additional functionality to the RTSP plugin
(it now handles redirects (301 and 302), however I must test it
thoroughly before submitting the patch).
RTSP server gives me the following line, describing media
m=video 0 RTP/AVP 26
when answers the DESCRIBE request.
RTP payload type 26 is Motion Jpeg (RFC 2035).
Consider rtpmpeg2tdepay:
$ gst-inspect rtpmpeg2tdepay
[skip]
SINK template: 'sink'
Availability: Always
Capabilities:
application/x-rtp
media: video
payload: [ 96, 127 ]
clock-rate: [ 1, 2147483647 ]
encoding-name: MP2T-ES
application/x-rtp
media: video
payload: 33
clock-rate: [ 1, 2147483647 ]
[skip]
Am I correct in thinking that this depayloader supports types 33, 96,
and 127?
If yes, then GStreamer looks like missing MJpeg depayloader.
However, it has generic depayloader rtpdepay.
How should I do with this depayloader?
Currently I am getting:
$ gst-launch rtspsrc location="rtsp://192.168.24.23/stream.cgi?usrid=0&mgrid=116&devtp=1&prtid=o1&devid=1&picsz=5000x5000" protocols=udp-unicast ! rtpdepay ! fakesink
Setting pipeline to PAUSED ...

RTSP server logs show that it receives PLAY request from gst-launch.
Removing rtpdepay from the pipeline above makes gstreamer to receive
packets and move them to the fake sink.
Am I doing something wrong?
Thanks
Vladimir
