88bd7fdc82 Drop DCTELEM typedef 
It does not help as an abstraction and adds dsputil dependencies.

bc92214e27 vc1dsp: mark put/avg_vc1_mspel_mc() always_inline 
This ensures that these functions are inlined into the per-position
entry points, allowing constant propagation as needed for proper
optimisation.

18% faster VC1 decoding on Cortex-A9.

c23acbaed4 Don't use ff_cropTbl[] for IDCT. 
Results of IDCT can by far outreach the range of ff_cropTbl[], leading
to overreads and potentially crashes.

7d2e03afc8 vc1: make overlap filter for I-frames bit-exact. 2011-05-04 07:40:53 -04:00
Ronald S. Bultje
18b6a69ce9 Revert "VC1: merge idct8x8, coeff adjustments and put_pixels." 
This reverts commit f8bed30d8b. The reason
for this is that the overlap filter, which runs after IDCT, should run
on unclamped values, and thus IDCT and put_pixels() cannot be merged if
we want to attempt to be bitexact.

f8bed30d8b VC1: merge idct8x8, coeff adjustments and put_pixels. 
Merging these functions allows merging some loops, which makes the
results (particularly after SIMD optimizations) much faster.

3d1b1caa6b Remove duplicate definitions of fullpel MC functions 
This removes duplicated definitions of 8x8 and 16x16 fullpel MC
functions with various names reducing dsputil.o by 8k on x86_64.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

4f717c69ed idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. 
Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).
