While testing new SDL-1.2 SVN tree on OS X with dual binary (using the Fat build scripts), and SMPEG, the playsmpeg program causes a crash on Intel. Here is a gdb backtrace:

A similar crash also occurs in testoverlay.c

When I run a PowerPC playsmpeg (by using lipo to strip out the ppc only executable), it works just fine, so I'm not sure if this is really Apple's fault and there is something broken in Quicktime, or if something is broken in SDL.

I'd like to say I have this bug too, same symptom, same crash point, macbook pro, on first SDL_DisplayYUVOverlay with a YV12 overlay. Will try it on ppc next.

Fix yuv crash for MacOS X intel

The bug is in src/video/quartz/SDL_QuartzYUV.m. The PlanarPixmapInfoYUV420 MUST be a big-endian struct. (See ImageCompression.h, kYUV420PixelFormat constant definition). I post a patch against SDL 1.2.9.

This fix is in subversion, thanks!
