There a solution to transcode live/video (HLS/MP4) stream to RTMP (Facebook) using ffmpeg .

Transcode HLS To RTMP (Facebook live)

ffmpeg -re -i "http://domain/x/x/input.m3u8" -acodec libmp3lame -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 426x240 -bufsize 6000k -vb 400k -maxrate 1500k -deinterlace -vcodec libx264 -preset veryfast -g 30 -r 30 -f flv "rtmp://rtmp-api.facebook.com:80/rtmp/111111111111111?ds=1&a=XXXXXXXXXXXXXXXXX"

Transcode MP4 To RTMP (Facebook live)

ffmpeg -re -i ./video.mp4 -acodec libmp3lame  -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 426x240 -bufsize 6000k -vb 400k -maxrate 1500k -deinterlace -vcodec libx264 -preset veryfast -g 30 -r 30 -f flv "rtmp://rtmp-api.facebook.com:80/rtmp/111111111111111?ds=1&a=XXXXXXXXXXXXXXXXX"

call the following code to initialize a pop-up window with control that determine where to direct your POST request.

<script>
document.getElementById('liveButton').onclick = function() {
  FB.ui({
    display: 'popup',
    method: 'live_broadcast',
    phase: 'create',
}, function(response) {
    if (!response.id) {
      alert('dialog canceled');
      return;
    }
    //rtmp://rtmp-api.facebook.com:80/rtmp/111111111111111?ds=1&a=XXXXXXXXXXXXXXXXX
    alert('stream url:' + response.stream_url);
    FB.ui({
      display: 'popup',
      method: 'live_broadcast',
      phase: 'publish',
      broadcast_data: response,
    }, function(response) {
    alert("video status: \n" + response.status);
    });
