几秒钟后，ffmpeg 直播停止到 facebook

Question

我正在尝试使用以下设置将直播流式传输到 Facebook:

{
    '-i' : 'rtmp://localhost/live/mystream',
    '-f' : 'flv rtmps://live-api-s.facebook.com:443/rtmp/#key',
    '-g' :'30' ,
    '-r' :'30',
    '-c:a': 'aac',
    '-strict': '-2',
    '-c:v': 'h264',
    '-b:v': '768k',
    '-b:a' : '256k',
    '-preset': 'ultrafast',
    '-tune': 'stillimage',
    '-pix_fmt': 'yuvj444p',
    '-profile:v': 'high',
    '-level': '4.1'
}

但是流停止并显示此消息:

我还收到来自 Facebook 的消息:

Audio using unsupported codec
Please set the audio codec for the stream to a supported codec (AAC). If you continue without updating, viewers may experience lower audio quality or the stream may terminate.

我尝试了在stackoverflow上可以找到的所有设置，尽管当我流式传输到youtube时它工作正常，但没有任何工作，我做错了什么？谢谢

Answer 1

地方

'-f' : 'flv rtmps://live-api-s.facebook.com:443/rtmp/#key',

在阵列的末尾。
所有输出选项都必须位于输出 URL 之前。
