Re: [FFmpeg-devel] [PATCH 2/2] lavc/blockdsp: R-V V fill_block

[flow gg <hlefthleft@gmail.com>]

Hi, I initially used a loop, but according to libavcodec/blockdsp.h,

the maximum is 8x16 = 128 bytes, so using ff_get_rv_vlenb() >= 16 and m8
does not require a loop.

```
/* add and put pixel (decoding)
 * Block sizes for op_pixels_func are 8x4,8x8 16x8 16x16.
 * h for op_pixels_func is limited to { width / 2, width },
 * but never larger than 16 and never smaller than 4. */
typedef void (*op_fill_func)(uint8_t *block /* align width (8 or 16) */,
                             uint8_t value, ptrdiff_t line_size, int h);
```
