Convert mp3 to aac stream for facebook video with ffmpeg
17 août 2022, par Miro BarsocchiI want to start a live video in a Facebook page and I can do this using ffmpeg. The input is, as a video stream, a static image, suppose image.jpg and as audio a streaming content that currently is in mp3 format.
Due to facebook limitation, the audio format should be aac, so the idea is to convert the audio from mp3 to aac and send everything to facebook. What I'm using is this command


ffmpeg -loop 1 -f image2 -i image.jpg -i https://some.streaming.service/mp3 -c:a libfdk_aac -pix_fmt yuv420p -profile:v baseline -bufsize 6000k -maxrate 1500k -vcodec libx264 -preset veryfast -g 30 -r 30 -f flv -flvflags no_duration_filesize "rtmps://live-api-s.facebook.com:443/rtmp/FB-KEYTOSTREAM"



where
https://some.streaming.service/mp3
is a streaming in mp3 format. It "almost" work in the sense that it returns no error but I can not start streaming because, from facebook side, it seems that I'm not sending the stream : the "Start Live session" is not enabled



If I stop ffmpeg, then for a second, the button is enabled and I can stream a few seconds of what I want. It seems that the error is related to the fact that there is no buffer of data that arrives, will be converted, and directly sent to the output. If, instead of a mp3 streaming audio, I use a mp3 file then no problem.


I'm quite sure that ffmpeg can do this type of conversion, but can someone help me understand the flag(s) that I'm missing ?


I've tried also with
-re
with no luck.

Special handle on DC only inverse 8x8 2D-DCTThis commit enables a special handle for the 8x8 inverse 2D-DCT,
where only DC coefficient is quantized to be non-zero. For bus_cif
