Warning

You need ffmpeg 6.1.1 or higher version for publishing via Enhanced RTMP.

ffmpeg -i /opt/flussonic/priv/bunny.mp4 -c:v libx265 -preset fast -c:a copy -f flv rtmp://localhost:1935/static/published

If everything is configured correctly, you will see the file broadcast on your YouTube channel.

What if the stream has no audio?

YouTube's pipeline requires audio in all videos. It may happen that your video has no audio, for example, if it is a stream from an IP camera or published via WebRTC from a browser. Flussonic Media Server can add an empty, silent audio track to the stream so that it plays normally on YouTube.

To add the silent track to the stream:

  1. Go to Input tab in the stream profile and click Options next to the input URL.
  2. Select Add_AAC in the Output audio list.
