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
