Macros
#define	AV_CODEC_CAP_DRAW_HORIZ_BAND   (1 << 0)
	Decoder can use draw_horiz_band callback. More...
#define	AV_CODEC_CAP_DR1   (1 << 1)
	Codec uses get_buffer() or get_encode_buffer() for allocating buffers and supports custom allocators. More...
#define	AV_CODEC_CAP_DELAY   (1 << 5)
	Encoder or decoder requires flushing with NULL input at the end in order to give the complete and correct output. More...
#define	AV_CODEC_CAP_SMALL_LAST_FRAME   (1 << 6)
	Codec can be fed a final frame with a smaller size. More...
#define	AV_CODEC_CAP_SUBFRAMES   (1 << 8)
	Codec can output multiple frames per AVPacket Normally demuxers return one frame at a time, demuxers which do not do are connected to a parser to split what they return into proper frames. More...
#define	AV_CODEC_CAP_EXPERIMENTAL   (1 << 9)
	Codec is experimental and is thus avoided in favor of non experimental encoders. More...
#define	AV_CODEC_CAP_CHANNEL_CONF   (1 << 10)
	Codec should fill in channel configuration and samplerate instead of container. More...
#define	AV_CODEC_CAP_FRAME_THREADS   (1 << 12)
	Codec supports frame-level multithreading. More...
#define	AV_CODEC_CAP_SLICE_THREADS   (1 << 13)
	Codec supports slice-based (or partition-based) multithreading. More...
#define	AV_CODEC_CAP_PARAM_CHANGE   (1 << 14)
	Codec supports changed parameters at any point. More...
#define	AV_CODEC_CAP_OTHER_THREADS   (1 << 15)
	Codec supports multithreading through a method other than slice- or frame-level multithreading. More...
#define	AV_CODEC_CAP_VARIABLE_FRAME_SIZE   (1 << 16)
	Audio encoder supports receiving a different number of samples in each call. More...
#define	AV_CODEC_CAP_AVOID_PROBING   (1 << 17)
	Decoder is not a preferred choice for probing. More...
#define	AV_CODEC_CAP_HARDWARE   (1 << 18)
	Codec is backed by a hardware implementation. More...
#define	AV_CODEC_CAP_HYBRID   (1 << 19)
	Codec is potentially backed by a hardware implementation, but not necessarily. More...
#define	AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE   (1 << 20)
	This codec takes the reordered_opaque field from input AVFrames and returns it in the corresponding field in AVCodecContext after encoding. More...
#define	AV_CODEC_CAP_ENCODER_FLUSH   (1 << 21)
	This encoder can be flushed using avcodec_flush_buffers(). More...
