[FFmpeg-devel] [PATCH] IFF: Change decodeplane8 while to do ... while for getting 1% speedup
Sun May 9 23:55:14 CEST 2010
The patch from Mans which fixed the 8 pixels to less decoded per line
issue, causes crazy assembly code on gcc with x86_32.
So I changed this after discussing with Mans to make a do ... while loop
Please note that this patch has the side effect that a width <= 0 is
illegal, so this patch should only be applied after the width and height
Benchmarking it resulted in a 1% speedup using MRLake.iff.
I tested this patch also against lms-matriks.ilbm which decodes still
