Hello!
I’m currently trying to demo the nvof gstreamer pipeline based on the deepstream sample (as found in /opt/nvidia/deepstream/deepstream-5.1/sources/apps/sample_apps/deepstream-nvof-test).
The executable runs great from url sources. But when I modify the input to be ‘nvarguscamerasrc’, the performance drops.
Here is a minimal example with command line pipelines:
-
gst-launch-1.0 videotestsrc is-live=true ! nvvideoconvert ! 'video/x-raw(memory:NVMM)' ! m.sink_0 nvstreammux name=m width=640 height=480 batch-size=1 batched-push-timeout=34000 ! nvof ! nvofvisual ! nvoverlaysink
→ works great -
gst-launch-1.0 nvarguscamerasrc bufapi-version=1 ! nvoverlaysink
→ works great -
gst-launch-1.0 nvarguscamerasrc bufapi-version= 1 ! m.sink_0 nvstreammux name=m width=640 height=480 batch-size=1 batched-push-timeout=34000 ! nvof ! nvofvisual ! nvoverlaysink
→ very bad performance
Do you have any idea where this might come from? I’ve tried to tinker with the nvarguscamerasrc capabilities, with no luck to this point.
Thanks,
Mickaël
