Info

The following tests were done with an IMX577 camera connected to the Dragonwing IQ-9075 EVK

Video Decoding

These elements are supported for the Ubuntu Image (Ubuntu 24.04.04) and files with a 1080p resolution generated in the last section were used to test average performance and element latency.

CPU Decoders

These are the supported CPU Decoders for the Dragonwing EVK Board:

• avdec_h264
  • Example pipeline for the avdec_h264 element:

gst-launch-1.0 -v filesrc location=avdec_h264-test.mp4 ! qtdemux ! h264parse ! avdec_h264 ! waylandsink

• Performance measurements for the avdec_h264 element:

Resolution	%MEM	RSS (KB)	GPU Utilization (%)	FPS	Mean FPS	CPU Usage (%)
1280x720	0.2	86240	0.88	29.990	30.092	6
1920x1080	0.3	118548	1.70	30.005	30.098	6
3840x2160	0.9	328588	1.69	29.988	30.057	11

• avdec_h265:
  • Example pipeline for the avdec_h265 element:

gst-launch-1.0 -v filesrc location=avdec_h265-test-test.mp4 ! qtdemux ! h265parse ! avdec_h265 ! waylandsink

• Performance measurements for the avdec_h264 element:

Resolution	%MEM	RSS (KB)	GPU Utilization (%)	FPS	Mean FPS	CPU Usage (%)
1280x720	0.2	96436	0.59	15.942	18.275	7
