We’re having problems decoding and rendering an incoming RTSPS stream as compared to a standard RTSP stream.

We can reproduce what we believe is the issue with the following gst-launch command.

gst-launch-1.0 rtspsrc location="rtsps://192.168.0.40:30322/stream-eo" tls-validation-flags=4 latency=100 ! rtph264depay ! queue ! h264parse ! nvv4l2decoder ! nvvideoconvert ! nveglglessink

WARNING: from element /GstPipeline:pipeline0/GstEglGlesSink:eglglessink0: A lot of buffers are being dropped.
Additional debug info:
gstbasesink.c(3003): gst_base_sink_is_too_late (): /GstPipeline:pipeline0/GstEglGlesSink:eglglessink0:
There may be a timestamping problem, or this computer is too slow.

When testing with our application, we tried setting the sync property to false… not much of a difference.

The video below shows the rendering/throughput issue on the left using gstreamer - and on the right using opencv which seems to work fine. I’m including this in the hopes that someone might recognize the issue.

If anyone has any experience with RTSPS and the gstreamer rtspsrc plugin, Any help would be greatly appreciated.

Regards,
Robert.

Can you monitor the CPU loading and GPU loading while running the pipeline you post?

The GPU loading can be monitored by “nvidia-smi dmon”.

What is the CPU loading?

It seems to consume about 20-30%

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

Can you set “sync=0” with the nveglglessink in the pipeline?
