I can split an aid (or video) file by time, but how do I split it by file size?
ffmpeg -i input.mp3 -ss S -to E -c copy output1.mp3 -ss S -to E -c copy output2.mp3
Which is fine if I have time codes, but if I want the output files to be split at 256MB regardless of the time length, what do I do? (What I am doing now is estimating, but that often means I have to make multiple runs at it with
-ss S -to E to get files that are close to where I want in size).
