@ -429,7 +429,10 @@ typedef struct SwsContext {
* @param dstW width of destination image
* @param src pointer to source data to be scaled. If scaling depth
* is 8, this is 8bpp in 8bpp (uint8_t) width. If scaling
* depth is 16, this is 16bpp in 16bpp (uint16_t) depth.
* depth is 16, this is native depth in 16bbp (uint16_t)
* width. In other words, for 9-bit YUV input, this is
* 9bpp, for 10-bit YUV input, this is 10bpp, and for
* 16-bit RGB or YUV, this is 16bpp.
* @param filter filter coefficients to be used per output pixel for
* scaling. This contains 14bpp filtering coefficients.
* Guaranteed to contain dstW * filterSize entries.
