Anton Khirnov	e7078e842d	hevcdsp: add x86 SIMD for MC	9 years ago
Anton Khirnov	a853388d2f	hevc: change the stride of the MC buffer to be in bytes instead of elements 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.	9 years ago
Anton Khirnov	688417399c	hevcdsp: split the pred functions by width This should allow for more efficient SIMD.	9 years ago
Anton Khirnov	818bfe7f0a	hevcdsp: split the epel functions by width This should allow for more efficient SIMD.	9 years ago
Anton Khirnov	1f821750f0	hevcdsp: split the qpel functions by width instead of by the subpixel fraction This should allow for more efficient SIMD. Keep the C versions as they are now, to allow the compiler to inline the interpolation coefficients.	9 years ago
Anton Khirnov	d8ebb6157d	hevcdsp: fix a function name put_weighted_pred_avg should be put_unweighted_pred_avg, there is no weighting there.	9 years ago
Anton Khirnov	de1f8ead89	hevcdsp_template: templatize transquant_bypass	10 years ago
Anton Khirnov	73bb8f61d4	hevcdsp: remove an unneeded variable in the loop filter beta0 and beta1 will always be the same	11 years ago
Luca Barbato	8eeacf31c5	hevc: Do not left shift a negative value in hevc_loop_filter_chroma	11 years ago
Guillaume Martres	faf03ecba0	hevc: Remove useless clip The src buffer should only contain values in the interval [0, (1 << BIT_DEPTH) - 1]. Since shift = (BIT_DEPTH - 5), src[x] >> shift must be in the interval [0, 31], so no clip is needed. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Guillaume Martres	a246d06fe0	hevc: clip pixels when transquant bypass is used The reconstructed picture should always be clipped (see section 8.6.5), previously we did not clip coding units where cu_transquant_bypass_flag == 1.
