Hello. I have the following 2 disctinct Jetson pipelines.
-
gst-launch-1.0 filesrc location=test_video.mp4 ! qtdemux name=demux demux.video_0 ! queue ! h264parse ! video/x-h264, width=3840, height=2160, format=NV12 ! nvv4l2decoder ! video/x-raw(memory:NVMM), width=3840, height=2160 ! nvvidconv ! nvoverlaysink -e

gst-launch-1.0 filesrc location=“test_video.mp4” ! qtdemux name=demux demux.video_0 ! queue ! h264parse ! omxh264dec disable-dvfs=1 ! nvoverlaysink -e
While running these pipelines and inspecting with jtop, I noticed the same profile: no CPU usage and no GPU usage and high NVDEC usage. My question is what is the difference between OMXH264DEC and NVV4L2DECODER?
