2013-04-15vp3: Use full transpose for all IDCTsRonald S. Bultje
This way, the special IDCT permutations are no longer needed. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code. Also remove the unused type == 0 cases from the plain C version of the idct. Signed-off-by: Martin Storsjö <martin@martin.st>
2013-02-09dsputil: Move rnd_avg inline functions to a separate headerDiego Biurrun
2013-01-29bfin: Separate VP3 initialization codeDiego Biurrun
2013-01-23Drop DCTELEM typedefDiego Biurrun
It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2013-01-23vp3dsp: don't do aligned reads on input.Ronald S. Bultje
The input is not guaranteed to be aligned.
2013-01-22vp3/5: move put_no_rnd_pixels_l2 from dsputil to VP3DSPContext.Ronald S. Bultje
The function is only used in VP3 and VP5, so no need to have it in DSPContext.
2013-01-20vp3: integrate clear_blocks with idct of previous block.Ronald S. Bultje
This is identical to what e.g. vp8 does, and prevents the function call overhead (plus dependency on dsputil for this particular function). Arm asm updated by Janne Grunau <janne-libav@jannau.net>. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
2012-08-15Don't include common.h from avutil.hMartin Storsjö

2012-07-18vp3: move idct and loop filter pointers to new vp3dsp contextMans Rullgard
This moves all VP3-specific function pointers from dsputil to a new vp3dsp context. There is no reason to ever use the VP3 IDCT where an MPEG2 IDCT is expected or vice versa. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-03-06Don't use ff_cropTbl[] for IDCT.Ronald S. Bultje
Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
