Benchmark environment

The following setup was used for all the benchmarks:

• Qualcomm Dragonwing 9075 EVK
• Ubuntu 24.04 image provided by Canonical

The measurements are taken considering the following criteria:

• Average behaviour: measurements considering typical image processing pipelines. The CPU consumption excludes the video source overhead.

Benchmarking

Instruments:

• CPU: top command
• RAM: top command

Pipelines:

The following pipelines were used to measure the performance. The performance of pipeline with the element was measured while a client was consuming the data.

WIDTH=1280
HEIGHT=720
# Without the element 
gst-launch-1.0 qtiqmmfsrc ! "video/x-raw,format=NV12,width=$WIDTH,height=$HEIGHT,framerate=30/1" ! queue ! v4l2h264enc ! "video/x-h264,mapping=/stream1" ! h264parse config-interval=-1 ! fakesink

# With the element
