media/multimedia/ FFmpegOptions

This is a dumping ground for FFmpeg options I commonly use.

-c:a copy # don't transcode audio
-c:v copy # don't transcode video
-c copy # don't transcode
-b:a <audio_bitrate>

Mp3s

To convert all .m4a files to 160kbps .mp3 using bash (for casual listening through earbuds or an average stereo, 160kbps is fine – unless listening on my studio monitors I can't tell the difference, and wouldn't care if I could – for critical listening I use .wav or .flac)

for s in *.m4a; do
  ffmpeg -i "$s" -b:a 160k "${s%.m4a}.mp3"
done

and similarly for things like music videos downloaded from Youtube via youtube-dl.
