How to live stream on facebook via ffmpeg?
I am trying live streaming on facebook via ffmpeg but I get one error. As the error, I must use AAC instead of mp3. But I don't know how to do it.
Error: Bad audio codec 2 (MP3). Accepted audio codecs: AAC
Normally, I can run command below for youtube succesfully.
ffmpeg -i "rtmp://..." -deinterlace -vcodec libx264
-pix_fmt yuv420p -preset medium -r 30 -g 60 -b:v 2500k
-acodec libmp3lame -ar 44100 -threads 6 -qscale 3 -b:a
712000 -bufsize 512k -f flv "rtmp://a.rtmp.youtube.com/live2/key"
But when I run command below with facebook rtmp, error gets.
ffmpeg -i "rtmp://..." -deinterlace -vcodec libx264
-pix_fmt yuv420p -preset medium -r 30 -g 60 -b:v 2500k
-acodec libmp3lame -ar 44100 -threads 6 -qscale 3 -b:a
712000 -bufsize 512k -f flv "rtmp://rtmp-api.facebook.com:80/rtmp/key"
I am user of Ubuntu 14.04.
Thanks in advance.
Answer
In your ffmpeg command, you have this:
-acodec libmp3lame
This is encoding the audio stream into MP3. You'll need to change that. You might need to use something like this:
-acodec libfdk_aac

To reference Facebook's "Live Video Specs" from https://www.facebook.com/facebookmedia/get-started/live:
The Live API accepts H264 encoded video and AAC encoded audio only.
