Ability to override video API via script

[v2k]

If I'm not mistaken, there doesn't seem to be a way to override the video API. Would be nice to be able to set the video API in script. Unfortunately there are some blockers in the code that prevent this:

           private BaseMediaPlayer.CreateMediaPlayer(_videoApi);

Also, the options are get only:

	public OptionsWindows PlatformOptionsWindows { get { return _optionsWindows; } }

BaseMediaPlayer CreateMediaPlayer() is virtual, but nothing is really exposed to take advantage of this. _optionsWindows could also be protected as a solution.

Ability to do something like this, where videoApi could be set ahead of the creation of the media player:

public class AVProVideoAPI : MediaPlayer
{
    [SerializeField]
    public Windows.VideoApi _videoApi = Windows.VideoApi.MediaFoundation;

    public SetAPI(Windows.VideoApi api) { _videoApi = api; }

    public override BaseMediaPlayer CreateMediaPlayer()
    {
        BaseMediaPlayer mediaPlayer = null;

#if (UNITY_EDITOR_WIN) || (!UNITY_EDITOR && UNITY_STANDALONE_WIN)
        var options = PlatformOptionsWindows;
        options.videoApi = _videoApi;

        mediaPlayer = BaseMediaPlayer.CreateMediaPlayer(_videoApi);
        if (mediaPlayer == null)
        {
            mediaPlayer = base.CreateMediaPlayer();
        }
#else
        mediaPlayer = base.CreateMediaPlayer();
#endif

        return mediaPlayer;
    }
}

The obvious alternative is to edit the code, but it would be nice to avoid that.

To confirm, does setting the videoApi in script currently not actually change the API? We've been trying to use 'VideoPlayer.PlatformOptionsWindows.videoApi = Windows.VideoApi.DirectShow' to change from WinRT in our startup script depending on playback machine (Windows) - does this have no effect currently, and only set from the Editor VideoAPI selection?
