as far as I understood with L4T release 32.1 NVIDIA has deprecated OpenMAX API for video encoding. V4L API seems to be the main supported option now. But there’s a missing feature compared to OpenMAX - V4L lacks support for 10 bit H.265 encoding. Are there any plans to add it?
Also I wonder what does new V4L2_CID_MPEG_VIDEOENC_ENABLE_ALLIFRAME_ENCODE option do? Does it make every frame an I-frame?
