Is it possible to force pixel format other than BGRA through output connectors #9

I am looking to force pixel format other than BGRA through output connectors to sink display if it supports. If my sink display support YUV420 or YUV444 I want to force that pixel format. Is it possible to do so?

I am looking for the possibility to preserve pixel format from my decoder to the sink display. If my decoder decodes in YUV444 format I want to display that on sink with out a format conversion to BRGA/other RGB.

I got a Intel atom based ADL-N platform powered by Ubuntu 24.04 with 6.8 kernel.

Hi @akhilxavi

Unfortunately, it is not supported to force the pixel format at the moment. It is always expected to be BRGA.

Thank you for the reply. Is that because the Linux intel DRM driver not supporting or DRM API's not exposing the capability to specify output pixel format?
