Reimar Döffinger	d82729e5d9	Detect and skip mj2-style jp2c header. This this fixes one of the issues with http://blogs.bu.edu/mhirsch/files/2012/08/Rotate180CCW-checkerboard.mj2_.zip and at least allows to demux the file properly instead of failing during probing.

Christophe Gisquet	4a7af92cc8	sbrdsp: Unroll and use integer operations This patch can be controversial, by assuming floats are IEEE-754 and particular behaviour of the FPU will get in the way. Timing on Arrandale and Win32 (thus, x87 FPU is used in the reference). sbr_qmf_pre_shuffle_c: 115 to 76 sbr_neg_odd_64_c: 84 to 55 sbr_qmf_post_shuffle_c: 112 to 83 Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago

Diego Biurrun	9328062321	x86: dsputil: Move avg_pixels16_mmx() out of rnd_template.c The function does not do any rounding, so there is no point in keeping it in a round template file.	12 years ago

Michael Niedermayer	c1f2c4c3b4	vmdav: Try to fix unpack_rle() This fixes out of array accesses The code prior to this commit could not have worked, thus obviously was untested.
