List human-readable video title where possible in format list (-F) display

[i336]

I often use -F to list the possible video encoding formats I can use for videos.

When I do this, I see something like

[info] Available formats for dQw4w9WgXcQ:
...

which tells me nothing about the video.

I've recently discovered that the formats available for YouTube videos is unpredictable and depends on what batch-transcoding settings were in place when the video was originally uploaded.

If I do an -F request for several videos, I'll get a terminal full of "Available formats for ....." and I'll then need to repeatedly crossreference the video IDs manually to work out what to do next - I might want to find a higher quality copy of a given video, or I might only want the audio track of another, etc, but I can only make the appropriate judgement calls if I know the title of the video in question!

I would suggest [re]using the filename output format specifier (minus the file extension, if feasible) to control the presentation.

Thanks for such an awesome program, btw! :D

Using the filename could be triccky, it can contain info about the format (resolution, format_id ...). Would using the title be enough? (I think that's quite reasonable).

Ah, of course, I didn't think of that. I'm not that familiar with youtube-dl's internal structure, I was looking for an existing easily reusable datapoint to make the feature easier to implement.

Just the video title would certainly be sufficient.

:D

I'd also welcome the title in the format listing, as this tells more than Available formats for <ID>. At least on demand. I'd expect this when issuing --get-format and --get-title together, but currently this produces nothing instead of a format listing with titles, as I'd expect it. Thanks.
