Are there any examples of hardware decoding in real-time video?

Which system do you use? Android, Ubuntu, OOWOW or others?

Ubuntu

Which version of system do you use? Please provide the version of the system here:

Ubuntu 22.04

Post a console log of your issue below:

When loading RTSP video, the CPU load was higher than expected.

Is there a way to load RTSP video with hardware decoding?
If so, could you provide a simple example?

Is the work in progress?

@GHdevlog a google search shows your pipeline should be something like such for receiving RTSP streams:

gst-launch-1.0 rtspsrc location=rtsp://<server_ip>:<port>/<path> latency=100 ! queue ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! autovideosink

We can modify this to use the h264 decoder and use wayland for preview window like such

gst-launch-1.0 rtspsrc location=rtsp://<server_ip>:<port>/<path> latency=100 ! queue ! rtph264depay ! h264parse ! v4l2h264dec ! fpsdisplaysink video-sink=waylandsink sync=false text-overlay=false

I don’t have access to my board at the moment to test this out, but do share if it works, I can try debugging it a bit later :slightly_smiling_face:
