Scaled horizontal lines ring buffer. | |
The horizontal scaler keeps just enough scaled lines in a ring buffer so they may be passed to the vertical scaler. The pointers to the allocated buffers for each line are duplicated in sequence in the ring buffer to simplify indexing and avoid wrapping around between lines inside the vertical scaler code. The wrapping is done before the vertical scaler is called. | |

void(* SwsContext::hyscale_fast) (struct SwsContext *c, int16_t *dst, int dstWidth, const uint8_t *src, int srcW, int xInc) |
Scale one horizontal line of input data using a bilinear filter to produce one line of output data.
Compared to SwsContext->hScale(), please take note of the following caveats when using these:

void(* SwsContext::hcscale_fast) (struct SwsContext *c, int16_t *dst1, int16_t *dst2, int dstWidth, const uint8_t *src1, const uint8_t *src2, int srcW, int xInc) |

void(* SwsContext::hyScale) (struct SwsContext *c, int16_t *dst, int dstW, const uint8_t *src, const int16_t *filter, const int32_t *filterPos, int filterSize) |
Scale one horizontal line of input data using a filter over the input lines, to produce one (differently sized) line of output data.
dst | pointer to destination buffer for horizontally scaled data. If the number of bits per component of one destination pixel (SwsContext->dstBpc) is <= 10, data will be 15 bpc in 16 bits (int16_t) width. Else (i.e. SwsContext->dstBpc == 16), data will be 19bpc in 32 bits (int32_t) width. |
dstW | width of destination image |
src | pointer to source data to be scaled. If the number of bits per component of a source pixel (SwsContext->srcBpc) is 8, this is 8bpc in 8 bits (uint8_t) width. Else (i.e. SwsContext->dstBpc > 8), this is native depth in 16 bits (uint16_t) width. In other words, for 9-bit YUV input, this is 9bpc, for 10-bit YUV input, this is 10bpc, and for 16-bit RGB or YUV, this is 16bpc. |
filter | filter coefficients to be used per output pixel for scaling. This contains 14bpp filtering coefficients. Guaranteed to contain dstW * filterSize entries. |
filterPos | position of the first input pixel to be used for each output pixel during scaling. Guaranteed to contain dstW entries. |
filterSize | the number of input coefficients to be used (and thus the number of input pixels to be used) for creating a single output pixel. Is aligned to 4 (and input coefficients thus padded with zeroes) to simplify creating SIMD code. |
