Add Youtube DL options support

[LawrenceJGD]

You could add Youtube DL options such as changing the video format or even give options using --ytdl-raw-options, it would be very useful for certain scripts to choose predefined formats.

Sorry for my bad English.

That's already supported under the name of option access. You could either do it at initation (e.g. mp = MPV(ytdl_format='best')) or like in the given link.

Oh, I had not seen it, but is it possible to do something similar to --ytdl-format=244+bestaudio? because I can not make it work well.

Excuse me if I ask silly questions, I'm a novice in programming.

[McSinyx]

I'm afraid that 244+bestaudio is not a valid format. It can only be either a format code (244), or an expression describing the format (bestaudio), not both.

Edit: Accept my apology, 244+bestaudio does work because the format 244 is video only. Does this work for you:

from mpv import MPV

mp = MPV(ytdl=True, ytdl_format='244+bestaudio', input_default_bindings=True,
         input_vo_keyboard=True)
mp.play('https://www.youtube.com/watch?v=n5PvkLg8LQk')
mp.wait_for_playback()
mp.quit()

Now it works, thanks for the help.

[McSinyx]

I'm glad to hear so. If everything runs fine, please close the issue. Thanks.

Apparently ytdl_raw_options doesn't work, i'm trying to use --no-cache-dir because that's a fix from their issues section. Edit: it actually works, and just for the sake of people like me that can't find any information about this heres what you do: player = mpv.MPV(ytdl=True,ytdl_raw_options="no-cache-dir=" if you have a no argument flag you have to end with '=', that was my problem.

The following works:

import mpv                                                                                                              
player = mpv.MPV(ytdl = True, log_handler=print, loglevel='debug', ytdl_raw_options='foo=bar,baz=23')
player.play('https://www.youtube.com/watch?v=SkgTxQm9DWM')

You can see that the correct options are passed to youtube-dl in the console debug output. Direct passthrough of python dicts as MPV node objects indeed seems to be broken, but the fall-back to passing command-line strings is ok I think.

You can also change this option at runtime, AFAICT with the updated arguments being used for the next youtube-dl invocation:

player['ytdl-raw-options'] = 'foo=bar,baz=42'
