[PATCH 0/2] MR2815: winegstreamer: Fix IV50 video playback.

[PATCH 1/2] winegstreamer: Add a second videoconvert before the videoflip.

[Anton Baskanov]

From: Anton Baskanov

videoflip can't handle 15/16-bit RGB. Fixes video playback in multiple games (e.g. Hard Truck 2, Firestarter).

[PATCH 2/2] winegstreamer: Don't flip the video in video_decoder.

[Anton Baskanov]

From: Anton Baskanov

Flipping is done in ir50_32. Fixes upside-down videos in multiple games
(e.g. Hard Truck 2, Firestarter).

This feels wrong. Unless we have a good reason to do otherwise, we should be respecting the requested stride. If the problem is that ir50_32 is also flipping, it should be fixed to not do that.
