Use ffmpeg to stream live content to azure media services

Question

I've been trying to stream content to azure media services using ffmpeg as it's one of the options described here : http://azure.microsoft.com/blog/2014/09/18/azure-media-services-rtmp-support-and-live-encoders/

My command is :

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

I have made sure that the streaming endpoint has one active streaming unit, I also made sure that the channel is actually Ready and I even get it to start streaming (which makes a PublishURL available).

When I execute the ffmpeg command to start streaming, I keep getting the following error :

The Azure blog post clearly states that this should be possible but I can't find a working example anywhere.

Environment :

• MacOS Maverick
• FFMPEG installed from official build
• 300.mp4 : 1080p trailer of the latest 300 movie

Answer 1

I figured out the missing piece here ...

At the end of the publishURL, you need to add /mystream1 at the end. Hopefully, this helps somebody.
