Recommended Encoding Parameters

The following parameters are recommended for various purposes in CBR encoding (frame rate: $fps; bit rate: $bitrate) when the input file test.yuv is 1080p.

• Low latency

  ./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

• High definition

  ./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

• Video on demand

  ./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

• No special encoding requirements

  ./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
