My purpose is decoding a received from RTCP stream h264 AVPacket-s to AVFrame-s using by hardware of rk3399 (Rockchip RK3399 is a processor for computing(aarch64, Rockchip platform))
I found that rk3399 has mpp. Media Process Platform(mpp) is the video codec parser and Hardware Abstraction Layer library for the Rockchip platforms. Mpp provides C API for decoding h264 video files using by hardware of Rockchip platform. And now i am thinking that the problem is converting from AVPacket(contain H264 data from RTCP stream) to MppPacket(this packet i will send to hardware decoder) Thanks, Anton Prikazchikov >Понедельник, 9 апреля 2018, 20:06 +04:00 от Henri Zikken <zik...@xs4all.nl>: > >Ok, the rk339 is soms sort of computer.
