问使用ffmpeg将直播内容传送到蔚蓝媒体服务。

EN

我一直试图使用ffmpeg将内容流到蔚蓝媒体服务，因为这是这里描述的选项之一：http://azure.microsoft.com/blog/2014/09/18/azure-media-services-rtmp-support-and-live-encoders/

我的命令是：

ffmpeg -v verbose -i 300.mp4 -strict -2 -c:a aac -b:a 128k -ar 44100 -r 30 -g 60 -keyint_min 60 -b:v 400000 -c:v libx264 -preset medium -bufsize 400k -maxrate 400k -f flv rtmp://nessma-****.channel.mediaservices.windows.net:1935/live/584c99f5c47f424d9e83ac95364331e7

我已经确保流端点有一个活动的流单元，我还确保通道实际上已经准备好，甚至让它开始流(这使PublishURL可用)。

当我执行ffmpeg命令开始流时，我一直会得到以下错误：

Azure博客的文章明确指出，这应该是可能的，但我在任何地方都找不到一个有用的例子。

环境：

• MacOS Maverick
• FFMPEG从官方构建安装
• 300.mp4 :1080 p最新300部电影预告片
