Add --max-lenght

[davidhedlund]

Lot's of files that I have downloaded are longer then they supposed to, with no sound at the end. This can be avoided by adding a new option, --max-lenght (maximum download rate in bytes per second (e.g. 8:57)) which can be compared against youtubes data-context-item-time.

Example of a video with dead sound at the end of the track:

title="Antares - Sun Sanctuary";
youtube-dl "ytsearch10:$title" -f 172/171/43/webm/ogg --extract-audio --no-overwrites --match-title ^"$title"$ --verbose --ignore-errors --max-downloads 1

Except --max-lenght, other options should be included as well, like --lenght, and --min-lenght.

There is an option for lenght: --get-duration - simulate, quiet but print video length

But it does not let you set limitations.

You are proposing using a new option as a workaround for a bug (in YouTube or ffmpeg). I'd rather fix or work around the bug all the time.
