I have further investigated this problem and seem to have made some progress.
I now think that the change I was complaining about is actually correct. With
X set to 24-bit colour the overlay worked perfectly. It seems that the 16-bit
support was broken anyway, and this change simply made it a bit more broken.
I investigated the values of some of the registers while playing a video in
windows and discovered that (at least for my card) the colour key registers
are being set incorrectly by vidix. I have attached a patch that corrects the
problem for me.
I suspect that as is the patch will break other cards. I'm assuming the
colour key value was calculated that way for a particular reason. I do not
have any other cards to test this with and so am unable to determine for
which cards this fix needs to be activated. Anyone willing to test?
To add to this mess during my experimentations I have found that BGR 15-bit
support does not seem to be working properly. The video displays but has
somewhat psychedelic colours. I think I've spent enough time staring at hex
values over the past couple of days so will investigate this in the near
future (that is unless someone else wants to fix it!).
