Add direct mapping for quality related options
Add an option for -q:a and similar.
This is already available with your extra options, I will be working on a lot of mp3 files for DJ work. In my case it is (for libmp3lame) (for 190kbit/sec VBR):
c:a libmp3lame -e"-q:a 2"
Had to use " instead of ' for Windows
Probably should be a separate issue, but while the output options are handy, it would be nice to also have input-side options. I normalized a bunch of ancient mpg files that needed -fflags +genpts set for them, which was not possible without patching ffmpeg-normalize.
Yes, that could be done, but these would again apply to all input files, and it'd have to be quite generic since I couldn't possibly map all existing ffmpeg options. But I'll have a look.
Yeah I would imagine it would work just like the --extra-output-options param. Same deal, arbitrary string that gets inserted before -i.
This has been released in v1.20.0 via the -ei/--extra-input-options option.
