How to send camera absolute time over gsteamer + rtsp

[terry8uwg2]

Hi ,

I am streaming rgb and depth camera frame over gstreamer to rtsp server on Nano. how could I send the camrea timestamp (absolute time) when remote client streaming it from the rtsp server. i knew that there is pts on the gstreamer buf but it looks like a relative time start from 0 .

The client is need synchronize depth and rgb frame based on the orignal system time on nano.

Thanks

Hi,
A simple way of starting RTSP server is to execute test-launch. We have an example in

VLC playing gstreamer flow

Please also try test-launch.c @ https://github.com/GStreamer/gst-rtsp-server/blob/master/examples/test-launch.c Target sudo apt-get install libgstrtspserver-1.0 libgstreamer1.0-dev gcc test-launch.c -o test-launch $(pkg-config --cflags --libs gstreamer-1.0 gstreamer-rtsp-server-1.0) ./test-launch “videotestsrc ! omxh265enc ! rtph265pay name=pay0 pt=96” Host Open network stream rtsp://<TARGET_IP_ADDRESS>:8554/test via VLC

However, it may not run as sending absolute time. The timestamping mechanism lies in gstreamer frameworks and suggest you go to
http://gstreamer-devel.966125.n4.nabble.com/

Gstreamer forum users should have more experience to share you suggestion and guidance. After you get a working pipeline with software encoder and decoder such as x264enc and avdec_h264, please replace them with nvv4l2h264enc and nvv4l2decoder to enable hardware acceleration.

@DaneLLL

nd suggest you go to

hi DaneLLL

Thanks the test-launch. i think i just need figure out how to pass the absolute time.

Thanks
