  • Using ffmpeg to stream to Facebook Live Video : can preview, but not go live

    17 novembre 2016, par Einar Magnússon

    I am trying to stream a webpage to Facebook Live video using ffmpeg. I know I can use OBS, but I’m trying to do it from a server, so I can’t go with OBS. It works fine when I’m previewing, but as soon as I press ’Go live’, at first it seems like it’s starting, but then when it takes me to the live view it just says that the video has ended. I even checked the error of the video log using Graph API, nothing. I’m using PhantomJS to pipe screenshots to ffmpeg :

    phantomjs phantom.js | ffmpeg -y -c:v mjpeg \
    
-f image2pipe \
    
-r 5 -i \
    
- -c:v libx264 \
    
-x264-params keyint=5 \
    
-b:v 1000k -minrate 1000k -maxrate 1000k -bufsize 500k \
    
-f flv 'rtmp://rtmp-api.facebook.com:80/rtmp/xxxxxxxxxxxxxxxx'

    As I said, it’s working fine in the preview of the live stream on Facebook, but just ends immediately when I go live. I added the bitrate options to try to keep a constant bitrate as mandated by Facebook (https://developers.facebook.com/docs/videos/live-video/production-broadcasts), and I have a keyframe every 5 frames (rather low frame rate at 5fps) so that requirement is fulfilled as well.

    I’m not sending any audio, could that cause a problem ?
