2013-02-13Remove 2nd-order transform for first-order DC coefficients.Ronald S. Bultje
Since addition of the larger-scale transforms (16x16, 32x32), these don't give a benefit at macroblock-sizes anymore. At superblock-sizes, 2nd-order transform was never used over the larger transforms. Future work should test whether there is a benefit for that use case.

2012-12-18Use standard integer types for pixel values and coefficients.Ronald S. Bultje
For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char). Change-Id: I3619cd9abf106c3742eccc2e2f5e89a62774f7da
2012-12-12Improved vp9_ihtllm_cScott LaVarnway
As suggested by Yaowu, we can use eob to reduce the complexity of the vp9_ihtllm_c function. For the 1080p test clip used, the decoder performance improved by 17%. Change-Id: I32486f2f06f9b8f60467d2a574209aa3a3daa435
