Hi @asadullah4571 ,

STM32MP1 does not embed any video HW accelerator, so video resolution, bit rate and frame rate is limited.

Played video files should be adapted to STM32MP1 capabilities.

Dual Cortex-A7 800MHz 32-bit DDR (STM32MP157F-DK2 is 16-bit DDR, so expect lower figures) :

• H264   : up to 720p 16/9 (1280x720) @ 24fps in full screen on a 720p (1280x720) display
• VP8     : up to 720p 16/9 (1280x720) @ 30fps in full screen on a 720p (1280x720) display

Notes:

• Color conversion, upscale & composition are performed with the GPU
• Video bitrates have to be below 1.5Mbps for good performances
