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_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 encoder can reorder user opaque values from input AVFrames and return them with corresponding output packets. More...

 

#define  AV_CODEC_CAP_ENCODER_FLUSH   (1 << 21)

  This encoder can be flushed using avcodec_flush_buffers(). More...

 

#define  AV_CODEC_CAP_ENCODER_RECON_FRAME   (1 << 22)

  The encoder is able to output reconstructed frame data, i.e. More...
