ppc: remove redundant setting of Altivec IDCT · ca6a9046

Mans Rullgard authored Jul 25, 2011

This is already set by dsputil_init_ppc() and is best done in only
one place.

mpegvideo: initialise DSPContext in ff_dct_common_init() · c3027b4d

Mans Rullgard authored Jul 25, 2011

The functions and tables initialised in this function rely on an
initialised DSPContext.  Make sure they always have one.

bink: make IDCT take 32-bit input · 2968bedf

Kostya Shishkov authored Jul 23, 2011

Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical
for most codecs, move Bink IDCT into separate context. Get rid of an additional
permutation table while at it since SIMD support for Bink IDCT is unlikely to
be implemented in foreseeable future.
Quantisation tables also have to change type to signed for proper
dequantisation of DCT coefficients.

x86: fix build with gcc 4.7 · da4c7cce

Mans Rullgard authored Jul 26, 2011

The upcoming gcc 4.7 has more advanced constant propagation
resulting some inline asm operands becoming constants and thus
emitted as literals, sometimes in contexts where this results
in invalid instructions.

This patch changes the constraints of the relevant operands
to "rm" thus forcing a valid type.  While obviously suboptimal,
this is what older gcc versions already did, and there is no
change to the code generated with these.

```
High bitdepth H.264 needs 32-bit transform coefficients, whereas
dnxhd does not.  This creates a conflict with the templated
functions operating on DCTELEM data.  This patch adds a field
allowing the caller to choose the element size in dsputil_init()
and adds the required functions.
