 I've found the reason for the crashes on video exit and fixed it:
 That's because IDirectXVideoDecoderService_CreateSurface
 creates surface_count + 1 surfaces (1 frontbuffer + surface_count
 backbuffers) but IDirectXVideoDecoderService_CreateDecoder is created with
 surface_count buffers.

 I also fixed the significant corruption when playback starts and following
 a skip:
 That's because of begin_frame in dxva2.c decoder fails. This
 patch fixes this.

 I've attached the two patches for fixes/0.26
