Function Documentation

static av_cold int decode_end ( AVCodecContext avctx  )  [static]

Definition at line 180 of file anm.c.

static int decode_frame ( AVCodecContext avctx,
void *  data,
int *  data_size,
AVPacket avpkt 
) [static]

Definition at line 109 of file anm.c.

static av_cold int decode_init ( AVCodecContext avctx  )  [static]

Definition at line 36 of file anm.c.

static int op ( uint8_t **  dst,
const uint8_t *  dst_end,
const uint8_t **  buf,
const uint8_t *  buf_end,
int  pixel,
int  count,
int *  x,
int  width,
int  linesize 
) [inline, static]

Perform decode operation.

dst,dst_end Destination image buffer
buf,buf_end Source buffer (optional, see below)
pixel Fill color (optional, see below)
count Pixel count
x Pointer to x-axis counter
width Image width
linesize Destination image buffer linesize
non-zero if destination buffer is exhausted
a copy operation is achieved when 'buf' is set a fill operation is acheived when 'buf' is null and pixel is >= 0 a skip operation is acheived when 'buf' is null and pixel is < 0
