Note
Measured using actual conditions, using GStreamer pipelines for decoding, composition, and display. Output was displayed with Wayland Desktop. Please refer to the datasheet for standalone capabilities of the Video decoder IP block.
In case of multiple video mixing, graphics content is set at 2K for SL1680/SL1640 and 1280x800 for SL1620.
For the consistency, cpufreq set to userspace and configured to be max. (SL1620: 1900000, SL1640: 2000000, SL1680: 2100000)

Note
To verify performance for codec block, basic GStreamer pipelines were executed. Adding extra overhead of video mixer or memory copy may impact the codec performance depending on usecase.
