问题描述
我想在 1 个 ffmpeg 过程中流式传输到 youtube 和 twitter
我红色这个https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs
我执行这个命令
/usr/bin/ffmpeg -re -i input.mp4 -deinterlace -c:v libx264 -pix_fmt yuv420p
-preset veryfast -tune zerolatency -profile:v main -c:a aac -b:a 128k -ac 2
-crf 19 -r 30 -g 60 -b:v 1369k -minrate 1369k -maxrate 1369k -bufsize 2738k
-ar 44100
-filter_complex "[0:v]split=2[s0]; [s0]scale=-2:1080[v0]"
-map "[v0]" -map 0:a
-f tee " [select='v:0,a':f=flv]rtmp://a.rtmp.youtube.com/live2/key | [select='v:0,a':f=flv]rtmps://va.pscp.tv:443/x/key "
然后我进入命令行

我的命令有什么问题？
解决方法
您需要对引号进行转义：list(set(outcomes)) 和 select=\'v:0,a\'
