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

The functions and tables initialised in this function rely on an initialised DSPContext. Make sure they always have one. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
