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.

• Limit performance: measurements by stressing the GStreamer element

GStreamer Bayer10 Support

GStreamer has support for 8-bit Bayer only. Please follow RidgeRun Wiki on Building custom v4l2src to support 10 bit Bayer.

Environment

Please, enable the display with the following instructions and set the following environment variables (if you are remotely connected to the board):

export QT_QPA_PLATFORM=wayland
