framebuffer in YUV420 mode

Hello all!

 

VPU decodes H264 frames in YUV420 planar format, and I was just wondering why shall IPU convert it to RGB565 if it's possible to set the framebuffer in YUV420 mode? Then the decoded bytes need only to be copied into the framebuffer (roughly).

 

Is it possible to set the framebuffer format to YUV420? I'm using SII902x HDMI converter and this kernel parameter now:

 

video=mxcdi0fb:RGB24,1920x1080M@60 hdmi di0_primary

 

All my attempts were failed to set to YUV420.
