将外面的流解码转发到自己的直播流接口

nohup ffmpeg -i "rtmp://rtmp01open.ys7.com/openlive/f01018a141094b7fa138b9d0b856507b.hd" -f flv -r 25 -s 640*640 -an "rtmp://localhost:2016/hls/demo"&

利用流文件生成m3u8文件

nohup ffmpeg -v verbose -i rtmp://localhost:2016/hls/demo -c libx264 -c:a aac -ac 1 -strict -2 -crf 20 -profile:v main -maxrate 800k -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -start_number 1 -f segment -segment_list demo.m3u8 -segment_list_flags +live -segment_time 10 out%03d.ts&
