Subject: Re: [SDL] SDL_DisplayYUVOverlay() segmentation fault

I wanted to add some information and rephrase my question.

The testoverlay.c and testoverlay2.c fail when the SDL_Rect.x/y != 0.
The following occurs:

Created 64x88X3 software YV12 overlay
  ...
X Error failed request:  BadValue (integer parameter out of range for
operation)
  Major opcode of failed request:  145 (MIT-SHM)
  Minor opcode of failed request:  3 (X_ShmPutImage)
  Value in failed request:  0x1b8
  Serial number of failed request:  40
  Current serial number in output stream:  41

This is fixed in CVS.
Comment 2 Sam Lantinga 2006-04-17 01:56:37 UTC 
Actually, this is active for all overlay drivers.
Comment 3 Sam Lantinga 2006-04-17 02:46:47 UTC 
The clipping is done at a higher level, and the low level functions are
passed clipped rectangles.  Drivers which don't support source clipping
have not been changed, so the image will be squished instead of clipped,
but at least they will no longer crash when the destination rect was out
of bounds.
