static int decode_frame(AVCodecContext *avctx, void *data, int *got_frame, AVPacket *avpkt)
static av_cold int decode_end(AVCodecContext *avctx)
#define CODEC_CAP_DR1
Codec uses get_buffer() for allocating buffers and supports custom allocators.
#define NULL_IF_CONFIG_SMALL(x)
Return NULL if CONFIG_SMALL is true, otherwise the argument without modification. ...
