[FFmpeg-user] Streaming to YouTube Live

Sat Apr 18 01:02:21 EEST 2020

I am uncertain whether this question is outside the scope of this forum, so
please advise me if it is.

I am attempting to stream a single static image to YouTube Live, using an
Amazon Linux server running on Amazon Lightsail, and using, of course,
ffmpeg.

I am using the following command:

/home/ec2-user/ffmpeg-git-20200324-amd64-static/ffmpeg -re -loop 1
-framerate 2 -i /home/ec2-user/testrun.jpg -s 1920x1080 -ab 128k -vcodec
libx264 -pix_fmt yuv420p -maxrate 2048k -bufsize 2048k -framerate 30 -g 2
-strict experimental -f flv
rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx

It is a command I adapted from the edit on the response of the solution
found on:

https://stackoverflow.com/questions/43586435/ffmpeg-to-youtube-live

The only modifications I have made to the core command is removing the audio
stream, and changing the output resolution to match the optimal resolution
recommended for YouTube.

-

The resulting problem is that while ffmpeg appears to be successfully
streaming data, albeit with a few warnings I do not have an understanding
of, YouTube is not receiving data. Thank you for any assistance. I am
pasting the full out of my console below.

dg) has not been used for any stream. The most likely reason is either wrong
type (e.g. a video option with no video strea
ms) or that it is a private option of some encoder which was not actually
used for any stream.
