| * hevc: rename hevc.[ch] to hevcdec.[ch]Anton Khirnov2016-10-16
| | | | | | | | | | This is more consistent with the rest of libav and frees up the hevc.h name for decoder-independent shared declarations.

| * hevcdsp: add x86 SIMD for MCAnton Khirnov2015-12-05

| * hevc: change the stride of the MC buffer to be in bytes instead of elementsAnton Khirnov2015-12-05
| | | | | | | | | | | | Currently, the frame stride is passed in bytes, while the MC buffer size is in int16_t elements, This can be confusing, so pass both strides in bytes.
| * hevcdsp: split the pred functions by widthAnton Khirnov2015-12-05
| | | | | | | | This should allow for more efficient SIMD.
| * hevcdsp: split the epel functions by widthAnton Khirnov2015-12-05
| | | | | | | | This should allow for more efficient SIMD.
| * hevcdsp: split the qpel functions by width instead of by the subpixel fractionAnton Khirnov2015-12-05
| | | | | | | | | | | | | | This should allow for more efficient SIMD. Keep the C versions as they are now, to allow the compiler to inline the interpolation coefficients.
| * hevcdsp: fix a function nameAnton Khirnov2015-08-21
| | | | | | | | | | put_weighted_pred_avg should be put_unweighted_pred_avg, there is no weighting there.
