Codec uses get_buffer() for allocating buffers and supports custom allocators.
If not set, it might not use get_buffer() at all or use operations that assume the buffer was allocated by avcodec_default_get_buffer.

#define CODEC_CAP_DELAY 0x0020 |
Encoder or decoder requires flushing with NULL input at the end in order to give the complete and correct output.
NOTE: If this flag is not set, the codec is guaranteed to never be fed with with NULL data. The user can still send NULL data to the public encode or decode function, but libavcodec will not pass it along to the codec unless this flag is set.
Decoders: The decoder has a non-zero delay and needs to be fed with avpkt->data=NULL, avpkt->size=0 at the end to get the delayed data until the decoder no longer returns frames.
Encoders: The encoder needs to be fed with NULL data at the end of encoding until the encoder no longer returns data.
NOTE: For encoders implementing the AVCodec.encode2() function, setting this flag also means that the encoder must set the pts and duration for each output packet. If this flag is not set, the pts and duration will be determined by libavcodec from the input frame.

#define CODEC_CAP_SUBFRAMES 0x0100 |
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.
This flag is reserved to the very rare category of codecs which have a bitstream that cannot be split into frames without timeconsuming operations like full decoding. Demuxers carring such bitstreams thus may return multiple frames in a packet. This has many disadvantages like prohibiting stream copy in many cases thus it should only be considered as a last resort.

enum AVCodecID |
Identify the syntax and semantics of the bitstream.
The principle is roughly: Two decoders with the same ID can decode the same streams. Two encoders with the same ID can encode compatible streams. There may be slight deviations from the principle due to implementation details.
If you add a codec ID to this list, add it so that
After adding new codec IDs, do not forget to add an entry to the codec descriptor list and bump libavcodec minor version.

int avcodec_open2 | ( | AVCodecContext * | avctx, |
const AVCodec * | codec, | ||
AVDictionary ** | options | ||
) |
Initialize the AVCodecContext to use the given AVCodec.
Prior to using this function the context has to be allocated with avcodec_alloc_context3().
The functions avcodec_find_decoder_by_name(), avcodec_find_encoder_by_name(), avcodec_find_decoder() and avcodec_find_encoder() provide an easy way for retrieving a codec.
avctx | The context to initialize. |
codec | The codec to open this context for. If a non-NULL codec has been previously passed to avcodec_alloc_context3() or avcodec_get_context_defaults3() for this context, then this parameter MUST be either NULL or equal to the previously passed codec. |
options | A dictionary filled with AVCodecContext and codec-private options. On return this object will be filled with options that were not found. |

int avcodec_close | ( | AVCodecContext * | avctx | ) |
Close a given AVCodecContext and free all the data associated with it (but not the AVCodecContext itself).
Calling this function on an AVCodecContext that hasn't been opened will free the codec-specific data allocated in avcodec_alloc_context3() / avcodec_get_context_defaults3() with a non-NULL codec. Subsequent calls will do nothing.

void avsubtitle_free | ( | AVSubtitle * | sub | ) |
