I’m running a gstreamer pipeline on a Jetson AGX Xavier devkit. The Jetson is connected to a camera with v4l2src interface. My problem is that most of the latency in the pipeline comes from nvvidconv which is unexpected. The pipeline is the following: GST_DEBUG="GST_TRACER:7" GST_TRACERS="proctime…

FYI: The solution to the above problem was using nvv4l2camerasrc instead of v4l2src. After this change, the pipeline can run at 60 fps no problem. So the final pipeline would be: gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! video/x-raw(memory:NVMM),format=UYVY,width=1920,height=1080 ! nvvid…

Update: Even the following simpler pipeline produces ~40 ms latency for nvvidconv GST_DEBUG="GST_TRACER:7" GST_TRACERS="proctime" gst-launch-1.0 v4l2src num-buffers=200 name=src_video0 device=/dev/video0 ! video/x-raw,format=YUY2,width=1920,height=1080,framerate=60/1 ! nvvidconv ! video/x-raw\(m…

Thank you! I tried that, now it is doing around ~40 fps. If I run the following command, I get 60 fps: gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY,width=1920,height=1080 ! fpsdisplaysink video-sink=fakesink text-overlay=false -v If I run the following command, I get 40 fp…

Is there anything else I could try to make this run at 60 fps? I also tried checking a pipeline with videotestsrc, and that has no problem producing 60 fps: gst-launch-1.0 videotestsrc ! video/x-raw,format=UYVY,width=1920,height=1080,framerate=60/1 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV…

Hi, Please set sync=0 to fakesink and check again: ... ! fpsdisplaysink text-overlay=false video-sink=fakesink sync=0

Nvvidconv is slow

Hi,
Please execute the steps to run hardware converter at maximum clock and check again:
