通过接口api/ctrl/start_relay_pull设置h265的rtsp流地址,flv方式预览加载失败

[zhengzhixiong]

设备是华为SDC,编码格式H265,分辨率2560*1440, 帧率30
前端flv报错:[TransmuxingController] > DemuxException: type = CodecUnsupported, info = Flv: Unsupported codec in video frame: 12

用ffmpeng推流的时候，如果要flv.js再html能正常播放 （再手机浏览器是必须的，pc浏览器我试过不加这个参数也是能正常播放），需要-pix_fmt yuv420p参数。

去试试取消勾选视频，是否有音频播放

你试试ffplay能正常播放吗

lal支持h265 flv/rtmp。

但是由于rtmp官方标准不支持h265，所以原生的ffmpeg和vlc都无法直接播放h265 rtmp/flv。
你可以使用 lalext 项目里thirdparty/build.sh编译一个支持h265的ffmpeg。

另外，据说 EasyPlayer.js 也支持播放h265 rtmp/flv，你也可以试试。

我尝试了下直接用vlc播放rtsp流地址是可以,我是通过接口api/ctrl/start_relay_pull授权lal去拉取rtsp流,然后代发,尝试了海康和华为两款ipc,默认出厂都是h265都不行,修改了摄像机里的编码为h264就可以;我用ffmpeg推流到lal,推流参数:ffmpeg -re -rtsp_transport tcp -threads 1 -buffer_size 1024000 -max_delay 500000 -i rtsp://admin:[email protected]:554/LiveMedia/ch1/Media1 -c:v libx264 -b:v 350k -profile:v baseline -level 3.0 -acodec aac -strict experimental -ar 44100 -ac 2 -b:a 96k -fflags nobuffer -preset ultrafast -tune zerolatency -vcodec h264 -f flv -an rtmp://localhost:1935/live/ff80808181367aef01813680fdfe00f1 把h265转264再推送到lal,前端flv播放就ok

我目前还没用ffmpeg推流,走api/ctrl/start_relay_pull方式去设置拉流,如果rtsp流编码是h264都可以,h265就不可以,改成用ffmpeg去推送,推流参数:ffmpeg -re -rtsp_transport tcp -threads 1 -buffer_size 1024000 -max_delay 500000 -i rtsp://admin:[email protected]:554/LiveMedia/ch1/Media1 -c:v libx264 -b:v 350k -profile:v baseline -level 3.0 -acodec aac -strict experimental -ar 44100 -ac 2 -b:a 96k -fflags nobuffer -preset ultrafast -tune zerolatency -vcodec h264 -f flv -an rtmp://localhost:1935/live/ff80808181367aef01813680fdfe00f1 把h265转264再推送到lal,前端flv播放就ok

[q191201771]

flv.js不支持h265 flv/rtmp

[zhengzhixiong]

ok,了解,感谢您的解答,接口是否考虑将h265内部自动转h264,然后代发出去,或者提供ffmpeg调用方式去实现推流
