Unable to push a transcoded stream to Facebook

Unable to push a transcoded stream to Facebook

Hi everyone, I have a pb with pushing a transcoded stream to Facebook (while I don’t have any pb with pushing the original stream to facebook, i.e. with no transcoding) To make it easier to explain and independent of my input stream, I also tried with a local file, that I am first transcoding and then pushing to facebook. I am doing it on the command line (but this is exactly what would be done by emstranscoder.sh script): /usr/bin/evo-avconv -y -i <local_file.mp4> -b:v 4000k -c:v libx264 -profile:v high -preset veryfast -g 60 -c:a copy -metadata streamName=transcoded_stream -f flv tcp://localhost:6666/ with “transcoded_stream” configured in EMS to be pushed to my facebook live page. This does not work (In the event logs of facebook, I have a succession of “Video signal lost” / “RTMP connection closed” messages) But this exact same configuration works perfectly for youtube and twitter.   Now if I push the transcoded file directly to facebook by changing the output of the command above like this: /usr/bin/evo-avconv -y -i <local_file.mp4> -b:v 4000k -c:v libx264 -profile:v high -preset veryfast -g 60 -c:a copy -metadata streamName=transcoded_stream -f flv rtmp://<my_facebook_page> It works perfectly!   I am a bit stuck, don’t really understand what happens between EMS and facebook, why as soon as I transcode it does not work?   Thanks,   Emmanuel.

Hi Emmanuel, May we know the EMS version you are using?
Also, can you confirm if this is correct:  A. transcode source > push transcoded stream to FB [not OK] B. send transcoded stream to FB [OK]   Regards,

Hi, This is EMS 2.0 That’s right:
  • A scenario does not work,
  • B scenario works (i.e. launch of evo-avconv manually to directly send transcoded stream to Facebook)
Regards, Emmanuel.
