Bug ID: 58553
           Summary: VFW Capture Filter only outputs 24 bpp RGB images
           Product: Wine
           Version: 10.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: quartz
          Assignee: [e-mail]

The VFW Capture Filter is currently hard-coded to output 24 bpp RGB images at
the first resolution listed by v4l. While this is a functional implementation,
it's very limited, and incompatible with the way many applications use the
filter. Unity, for instance, requires a 32 bpp RGB image when trying to capture
camera data, which inevitably fails, since wine can only provide 24 bpp.

The result of all of this is that camera support in wine is very hit or miss,
only functioning if the app in question happens to request a 24 bpp image, or
is designed to work with multiple image formats as output. OpenCV seems capable
of using this 24 bpp image, while libdshowcapture and Unity are unable to
