a frame width that is not an exact multiple of 8. Testcase: 405.avi (356x240). Playing on an MMX capable x86 system using the x11 video-out driver results in a segfault. The MMX routines convert image data in quantities of 8 pixels in each loop, and the inner loop was not terminated in case there are only 1-7 pixels left, producing too much RGB output. For now, just ignore the last few pixels on each row, to avoid the segfaults. (Gives a black vertical border on the right, if you play a video with width%8 != 0) A possible future enhancement would be, to add a second loop to convert the last width%8 pixels to RGB using a byte loop. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@1307 b3059339-0415-0410-9bf9-f77b7e298cf2
