推荐编码参数

针对输入的test.yuv为1080p场景，恒定码率编码（帧率为$fps，码率为$bitrate）推荐编码参数。

• 低时延

  ./bin/CloudHw265App -c ~/dependency/lib/cfg/hw265_encoder.cfg -preset 6 -w 1920 -h 1080 -rc 0 -br $bitrate -pass 0 -fps_num $fps -fps_den 1 -timebase_den $fps -timebase_num 1 -keyInt $fps*2 -adap_i 0 -bframes 0 -delay 1 -FrmThreadNum 4 -WppThreadNum 4 -LookAheadThreads 3 -i test.yuv -b test.mp4

• 高清

  ./bin/CloudHw265App -c ~/dependency/lib/cfg/hw265_encoder.cfg -preset 6 -w 1920 -h 1080 -rc 0 -br $bitrate -pass 0 -fps_num $fps -fps_den 1 -timebase_den $fps -timebase_num 1 -keyInt $fps*2 -adap_i 0 -bframes 3 -delay 4 -FrmThreadNum 4 -WppThreadNum 4 -LookAheadThreads 3 -i test.yuv -b test.mp4

• 点播

  ./bin/CloudHw265App -c ~/dependency/lib/cfg/hw265_encoder.cfg -preset 2 -w 1920 -h 1080 -rc 0 -br $bitrate -pass 0 -fps_num $fps -fps_den 1 -timebase_den $fps -timebase_num 1 -keyInt $fps*2 -adap_i 1 -bframes 7 -delay 25 -FrmThreadNum 4 -WppThreadNum 4 -LookAheadThreads 3 -i test.yuv -b test.mp4

• 无编码场景要求

  ./bin/CloudHw265App -c ~/dependency/lib/cfg/hw265_encoder.cfg -preset 6 -w 1920 -h 1080 -rc 0 -br $bitrate -pass 0 -fps_num $fps -fps_den 1 -timebase_den $fps -timebase_num 1 -keyInt $fps*2 -adap_i 0 -bframes 3 -delay 4 -FrmThreadNum 4 -WppThreadNum 4 -LookAheadThreads 3 -i test.yuv -b test.mp4
