[PATCH 0/5] MR3938: winegstreamer: Implement CLSID_CMpegVideoCodec

[Alfred Agrell (＠Alcaro)]

Resolves https://bugs.winehq.org/show_bug.cgi?id=9127 . (Some of the named programs in that issue may require additional currently-missing functionality, I didn't check; but if so, that's separate issues.)

Tested with
- winetest on Windows 7
- winetest on Windows 10
- winetest in Wine, of course
- microkiri https://bugs.winehq.org/show_bug.cgi?id=9127#c102
- Wagamama High Spec Trial Edition https://wagahigh.com/download_trial.php#normal (ダウンロード means download)
- Ninki Seiyuu no Tsukurikata Trial https://archive.org/details/sayou_trial
(WMV files in microkiri and Wagamama don't work, but that's separate issues.)
