5c9f147e05 vc1dec: use s->start/end_mb_y instead of passing them as function args. 2011-05-04 07:40:02 -04:00

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.

ad1862d64a ALPHA: Replace sized int_fast integer types with plain int/unsigned. 
int/unsigned is the natural memory access type for CPUs, using sized types
for temporary variables, counters and similar just increases code size and
can possibly cause a slowdown.

767848d761 aacdec: remove sf_scale and sf_offset. 
Instead, scalefactors are adjusted by the offset amount, removing the need
for sf_scale, and the MDCT scales are adjusted to compensate for the higher
scalefactors. Floating-point output will be handled by modifying the MDCT
scales.

e4744b59aa Large intensity stereo and PNS indices are legal. Clip them instead of 
erroring out. A magnitude of 100 corresponds to 2^25 so the will most
likely result in clipped output anyway.

None of the conformance streams fall in the range that need to be clipped.

f4e043ff63 qpeg: use reget_buffer() in decode_frame()

This also set frame->reference to 3, as the frame will be requested
unmodified later so it shouldn't be modified by the application.

4f2954e232 smacker: remove unnecessary call to avctx->release_buffer in decode_frame() 
The release_buffer was cleaning the provided frame, thus causing the
successive call to avctx->reget_buffer() to allocate a new frame.  In
case the returned frame was not the same one previously returned but a
new one with different data, it resulted in artifacts.
