Chrome在104/105版本后,支持硬解h265,使得hls利用浏览器硬解特性播放h265视频。hls官方要求h265必须使用fmp4格式进行封装,因此本篇使用ffmpeg采集摄像头fmp4+h265 aac切片,并使用hls.js demo在chrome浏览器中播放测试。
操作系统:macos 11.6.1
浏览器: chrome 107,查看是否支持硬解("h265" | Can I use... Support tables for HTML5, CSS3, etc)
ffmpeg版本:5.1.2,支持libx265
hls.js demo版本:v1.2.7
- ffmpeg -f avfoundation -video_size 640x480 -framerate 30 -i "0:0" -c:v libx265 -tag:v hvc1 -c:a aac \
- -map 0 \
- -f hls \
- -hls_time 10 \
- -hls_flags delete_segments+append_list+split_by_time \
- -hls_segment_type fmp4 \
- -hls_list_size 10 \
- -hls_playlist_type vod \
- stream.m3u8
切片后的文件如下:

使用ffplay播放测试下
ffplay -i stream.m3u8
