Cedrus/CedarX pixel format limitation



Recommended Posts



I'm trying to work with the CedarX/Cedrus Video Engine (on Allwinner A20). It works smoothly with my patched FFmpeg; for example:

ffmpeg -f v4l2 -r 30 -pix_fmt nv12 -video_size 1280x720 -i /dev/video0 -vcodec cedrus264 -pix_fmt nv12 -qp 15 -f rtsp -rtsp_transport tcp rtsp://


I need to use pixel format RGB24, but as far as I understand, I'm limited to work with NV12 (or NV16) pixel format.


Does this limitation is due to:

  1. My FFmpeg patch (I think not...)
  2. CedarX/Cedrus driver implementation.
  3. Hardware limitation.


Thanks for the help,
