This section presents GStreamer pipelines to capture from a USB camera and perform encoding/decoding of video using the H.264 hardware codec of the Orin NX. Key performance indicators are measured using three power profiles (operation modes): MaxN, 25W, and 10W. Check our GStreamer Pipelines section to find more information about how we extracted the performance metrics presented in this section.

H264 Encoding

USB PTZ Fomako Camera

The pipelines in this section used a PTZ Fomako USB camera capturing at 1920x1080@30fps.

Encoding 1920x1080@30 and saving to file

The pipeline below can be used to capture, encode using the H.264 hardware codec, and store the video to file as an mp4 in the /tmp/filename.mp4 location. Table 2 shows the performance information for this pipeline.

FILE=/tmp/filename.mp4
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, width=1920, height=1080, framerate=30/1 ! nvvidconv ! 'video/x-raw(memory:NVMM), format=NV12' ! nvv4l2h264enc bitrate=8000000 ! h264parse ! qtmux ! filesink location=$FILE -e

Table 2: Performance of USB pipeline at 1920x1080@30 with nvv4l2h264enc

Operation Mode	CPU (%)	GPU (%)	FPS	Latency (ms)
MaxN	4.73	0	29.219	28.209
25W	5.82	0	29.179	28.021
10W	8.17	0	29.162	28.540

H264 Decoding

The following pipeline can be used to decode the videos recorded the USB camera. Table 3 shows the performance for decoding 1920x1080@30 videos.

FILE=/tmp/filename.mp4
gst-launch-1.0 filesrc location=$FILE ! qtdemux ! queue ! h264parse ! nvv4l2decoder ! nv3dsink -e

Table 3: Performance of decoding pipeline at 1920x1080@30

Operation Mode	CPU (%)	GPU (%)	FPS	Latency (ms)
MaxN	8.73	27.63	28.998	1560.147
25W	8.41	25.00	28.997	1560.651
10W	9.63	34.41	28.998	1560.795
