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'
}

但流停止并显示此消息：

我也收到来自 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 Whosebug 上可以找到的所有设置，但没有任何效果，尽管当我流式传输到 YouTube 时它工作正常，我做错了什么？谢谢

Answer 1

地点

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

在数组的末尾。

所有输出选项必须在输出 URL 之前。
