When trying to stream videos I receive an error about the aac encoder being experimental despite ffmpeg version no longer requiring that... according to the internets.
Troubleshooting Steps:
- Code: Select all
Added -strict 2 to the transcoder lines, but the log lines do not reflect this even after a restart.
Replacing /home/subsonic/transcoders/ffmpeg with a script:
/usr/bin/ffmpeg -strict 2 "${@}"
still comes up with the message.
It's almost like it's running it's own script somewhere else and the transcoding lines are completely ignored.
