SOPHGO FFMpeg README

This is SOPHGO FFMpeg project optimized for SOPHGO BM1682/1684/1684x AI chips. It provides hardware accelerations for video codecs and image processing filters. Also some enhancement for streaming protocal are included.

Changes

With officical FFMpeg, following changes are done in this project.

** h264_bm, hevc_bm, jpeg_bm codecs are implemented using video hardware engine in SOPHGO Chips for h264/hevc/jpeg decoder or encoder

** bmscale is implemented using image processing hardware in SOPHGO Chips for image processing

** GB2818 streaming protocal support is added in FFMpeg

** Several domenstic CPUs are supported

** Many improvements are customized for Chinese market
