| * hevc: Remove useless clipGuillaume Martres2014-01-211-1/+1
| | | | | | | | | | | | | | | | | | | | 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>
| * hevc: clip pixels when transquant bypass is usedGuillaume Martres2014-01-211-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* hevc: remove useless clip in FUNC(sao_band_filter)()Guillaume Martres2014-01-121-1/+1
| | | | | | | | | | | 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. This removes the code that was changed in 5856bca360c5bc3e340a357d91b1f993c80a7bea as the clip that was repositioned in that commit is removed Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
