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）为推荐编码参数。
- 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.265
- 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.265
- 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.265
- 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.265
- 开启HDR10功能（不支持HDR vivid）
./bin/CloudHw265App_10bit -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 -hdrMode 1 -max-cll 1000 -max-fall 300 -primaries-x0 8500 -primaries-y0 39850 -primaries-x1 6550 -primaries-y1 2300 -primaries-x2 35400 -primaries-y2 14600 -white-x 15630 -white-y 16450 -max-luminance 10000000 -min-luminance 1 -atc-sei 2 -color_p 9 -transfer 16 -col_matrix 9 -fullrange 1 -i test.yuv -b test.265
如需按HDR10标准编码视频，请参见表1进行参数配置。
