Receive rtsp in VLC

Artyom

Hi,

First of all, thanks a lot for the tutorials,
it's quite hard though to make it work even with such usefull info...

At the moment I'm stuck with a VLC problem. I'd like to receive and trascode the video stream to Mission Planner, like you did in the GStreamer tutorial. The problem looks like this:

I do successfully receive the stream in GStreamer, but VLC only shows the one frame of the video and then freezes like on the image above.
The commands that I used on RPi2 and .sdp file:

raspivid -n -w 1280 -h 720 -b 2000000 -fps 30 -t 0 -o - | \
gst-launch-1.0 rtpbin name=rtpbin \
-v fdsrc ! h264parse ! rtph264pay config-interval=1 pt=96  ! rtpbin.send_rtp_sink_0 \
rtpbin.send_rtp_src_0 ! udpsink port=5000 host=192.168.137.1 \
rtpbin.send_rtcp_src_0 ! udpsink port=5001 host=192.168.137.1 sync=false async=false \
udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0
 
v=0
s=ESP H264 STREAM
m=video 5000 RTP/AVP 96
a=rtpmap:96 H264/90000
a=cliprect:0,0,720,1280 
a=framerate:30.000000 
a=fmtp:96 media=video; clock-rate=90000; encoding-name=H264;
a=control:trackID=1

Would appreciate any sugestions. Thanks.

Hi Artyom, welcome.
I know that my tutorials are not perfect, but it should give people an idea on how to run everything. wink

I just fired up my RPI2 and copy pasted your code. I could`t reproduce the issue you have. My picture is clear as a day.
Tested on:

RPI2 with RTK image.

gStreamer 1.0

My pipeline with Web cam

gst-launch-1.0 rtpbin name=rtpbin \
-v v4l2src device=/dev/video0  ! h264parse ! rtph264pay config-interval=1 pt=96  ! rtpbin.send_rtp_sink_0 \
rtpbin.send_rtp_src_0 ! udpsink port=5000 host=10.0.0.225 \
rtpbin.send_rtcp_src_0 ! udpsink port=5001 host=10.0.0.225 sync=false async=false \
udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0

Could this issue be related to PI cam? or raspivid settings. If you try a lower resolution, would that help?

Artyom

Thanks for a quick reply,

I tried to lower the bitrate and resolution settings, no change.
Another way to accomplish this would be to encode stream to MJPEG in desktop-running GStreamer, right?
In this case I would have to use jpegenc and resink the stream? Then what exactly does the Mission Planner expect in the url field? How could it look like in this case?

I'm using this for receiving at the moment:

gst-launch-1.0 -v udpsrc port=5000 caps="application/x-rtp" ! rtph264depay ! decodebin ! queue ! autovideosink sync=f

I have never tried to transcode gstreamer to mission planner, so i dont really now, but i think it should work.
