Missing documentation for -b flag

Analyzed by developer: no

Description

The ffmpeg documentation at http://www.ffmpeg.org/ffmpeg.html contains numerous examples of setting the bitrate using '-b', but no actual documentation for it.

It still appears to work in recent builds, so probably the documentation for it should be brought back. Otherwise, it should be dropped from the examples.

Replying to foo:

The ffmpeg documentation at http://www.ffmpeg.org/ffmpeg.html contains numerous examples of setting the bitrate using '-b', but no actual documentation for it.

Where do you see no documentation for -b? Or do you mean man ffmpeg?

$ ffmpeg -h | grep -w "\-b"
-b bitrate          video bitrate (please use -b:v)

I didn't see any mention of -ab however.

It still appears to work in recent builds, so probably the documentation for it should be brought back. Otherwise, it should be dropped from the examples.

The doc source has been updated to change -b to -b:v and -b:a:
