Output Filename Template: Format, Quality, and Resolution Substitution Tags

[EveryDirection]

For the -o or --output option, looking at the documentation obtained via --help, there's currently no tags for format, quality, or resolution. For example, if we are downloading a YouTube video in 720p MP4 (format 22: mp4 [720x1280]), we should have tags to enable writing the following to the filename template:

%(format)s -> "22"
%(quality)s -> "720p"
%(resolution)s -> (whatever the true resolution of the video may be, which is not necessarily 720x1280 though it'll be in that range)

This seems to be a very simple feature to add that wouldn't take much coding, and it would be very helpful when downloading files in varying qualities. Thanks.

Actually, instead of %(resolution)s, you'd probably want to split it up for finer control and to allow the user to use whatever ordering (width x height or height x width) the user prefers:

%(height)s
%(width)s

[EveryDirection]

So, sometime in the past couple of months or so, the following tags (with examples) did get added to the program:

%(format)s -> "22 - 1280x720"
%(format_id)s -> "22"

which I do appreciate, but it'd be nice if we could get finer control over those; there's still no

%(quality)s
%(height)s
%(width)s

tags.

The height and witdth parameters are supported in some extractors (like vimeo, ted, gametrailers, mtv, comedycentral ...), but we need to migrate the youtube extractor to the new formats system.

All the tags are now supported for youtube videos, thanks for the report.

I just downloaded version 2014.03.03 to test.

There's no documentation on these tags via --help, which should be added.

%(height)s and %(width)s are supported now (thanks!). But %(quality)s and %(resolution)s remain unsupported --- not that they necessarily have to be supported, since they can be constructed out of the %(height)s and %(width)s tags, but since there's no actual documentation in the program on which tags are supported, I just thought I'd point that out here in case anyone was wondering exactly what is meant by "all" tags now being supported.

@EveryDirection Thank you for the note. I've documented height, width, and resolution, and set a sensible default if the latter is not set, but width and height are.
