YUV_Overlay in a VMware Guest Linux OS

SDL Development
1

Hello,

I have a video display application that makes use of the YUV_Overlay surface. This works great on a real Linux host, but when I try to use the same application in a VMware guest OS, the video outcome is not as expected for SDL_YV12_OVERLAY.

The YUV_Overlay->format states SDL_YV12_OVERLAY, and YUV_Overlay->hw_overlay is 0 as expected, since VMware doesn’t have Xv support.

Is there something I should be doing to correct the YUV color space? I was assuming that SDL handled all of this so that the YUV_ API could be used transparently.

Any help would be appreciated. I can supply good and bad pictures of the outcome.

Thanks!

Shane

Can you try the code from CVS?

Sam,

The latest SDL on CVS works! Does the 1.2.9 stable release have the
same fix?

Thanks!

I don’t believe it does. I think it’s broken MMX conversion code, which
is temporarily disabled in CVS.
