Summary of the bug:
Early versions of QuickTime player allowed videos with “skins”. The
“skins” themselves where contained directly in the video stream.
The skinned videos came with a special XML file, but with the .MOV
extension. This file refers to the actual video file, a window mask
(contentregion, black = visible, white = transparent) and a drag mask
(dragregion, black = draggable [that means the mouse becomes a drag cursor
if you move over this area], white = not draggable). Allowed file formats
for this masks are gif, tif and png. contentregion and dragregion can
refer to the same file.
An example file could look like this:
{{{
<?xml version="1.0"?>
<?quicktime type="application/x-qtskin"?>
<skin>
<movie src="actual_movie.mov"/>
<contentregion src="contentregion.png"/>
<dragregion src="dragregion.png"/>
</skin>
}}}
Currently, such a file is not supported. FFMpeg should at least open the
referred actual_movie.mov when you load such a file. It would also be nice
to have, when the contentregion is applied to the video as a simple alpha
mask. The dragregion can be ignored.
