◆ targa_encode_rle()

static int targa_encode_rle ( uint8_t *  outbuf,
int  out_size,
const AVFrame pic,
int  bpp,
int  w,

RLE compress the image, with maximum size of out_size.

Parameters
outbufOutput buffer
out_sizeMaximum output size
picImage to compress
bppBytes per pixel
wImage width
hImage height
Returns
Size of output in bytes, or -1 if larger than out_size
