Functions

static int vertClassify_TMPL (uint8_t src[], int stride, PPContext *c)
 Check if the middle 8x8 Block in the given 8x16 block is flat.
static void doVertLowPass_TMPL (uint8_t *src, int stride, PPContext *c)
 Do a vertical low pass filter on the 8x16 block (only write to the 8x8 block in the middle) using the 9-Tap Filter (1,1,2,2,4,2,2,1,1)/16.
static void vertX1Filter_TMPL (uint8_t *src, int stride, PPContext *co)
 Experimental Filter 1 will not damage linear gradients Flat blocks should look like they were passed through the (1,1,2,2,4,2,2,1,1) 9-Tap filter can only smooth blocks at the expected locations (it cannot smooth them if they did move) MMX2 version does correct clipping C version does not.
static void doVertDefFilter_TMPL (uint8_t src[], int stride, PPContext *c)
static void dering_TMPL (uint8_t src[], int stride, PPContext *c)
static void deInterlaceInterpolateLinear_TMPL (uint8_t src[], int stride)
 Deinterlaces the given block by linearly interpolating every second line.
static void deInterlaceInterpolateCubic_TMPL (uint8_t src[], int stride)
 Deinterlaces the given block by cubic interpolating every second line.
static void deInterlaceFF_TMPL (uint8_t src[], int stride, uint8_t *tmp)
 Deinterlaces the given block by filtering every second line with a (-1 4 2 4 -1) filter.
static void deInterlaceL5_TMPL (uint8_t src[], int stride, uint8_t *tmp, uint8_t *tmp2)
 Deinterlaces the given block by filtering every line with a (-1 2 6 2 -1) filter.
static void deInterlaceBlendLinear_TMPL (uint8_t src[], int stride, uint8_t *tmp)
 Deinterlaces the given block by filtering all lines with a (1 2 1) filter.
static void deInterlaceMedian_TMPL (uint8_t src[], int stride)
 Deinterlaces the given block by applying a median filter to every second line.
static void transpose1_TMPL (uint8_t *dst1, uint8_t *dst2, uint8_t *src, int srcStride)
 transposes and shift the given 8x8 Block into dst1 and dst2
static void transpose2_TMPL (uint8_t *dst, int dstStride, uint8_t *src)
 transposes the given 8x8 block
static void tempNoiseReducer_TMPL (uint8_t *src, int stride, uint8_t *tempBlurred, uint32_t *tempBlurredPast, int *maxNoise)
static av_always_inline void do_a_deblock_TMPL (uint8_t *src, int step, int stride, PPContext *c)
 accurate deblock filter
static void postProcess_TMPL (const uint8_t src[], int srcStride, uint8_t dst[], int dstStride, int width, int height, const QP_STORE_T QPs[], int QPStride, int isColor, PPContext *c2)
 Filters array of bytes (Y or U or V values).
static void blockCopy_TMPL (uint8_t dst[], int dstStride, const uint8_t src[], int srcStride, int levelFix, int64_t *packedOffsetAndScale)
 Copies a block from src to dst and fixes the blacklevel.
static void duplicate_TMPL (uint8_t src[], int stride)
 Duplicates the given 8 src pixels ? times upward.
