| #define AV_GET_BUFFER_FLAG_REF (1 << 0) |
| #define AV_CODEC_CAP_DRAW_HORIZ_BAND (1 << 0) |
| #define AV_CODEC_CAP_DR1 (1 << 1) |
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 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.
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 AV_CODEC_CAP_SMALL_LAST_FRAME (1 << 6) |
| #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.
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 carrying 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.

| #define AV_CODEC_CAP_AVOID_PROBING (1 << 17) |
Decoder is not a preferred choice for probing.
This indicates that the decoder is not a good choice for probing. It could for example be an expensive to spin up hardware decoder, or it could simply not provide a lot of useful information about the stream. A decoder marked with this flag should only be used as last resort choice for probing.
| #define AV_CODEC_CAP_HARDWARE (1 << 18) |
Codec is backed by a hardware implementation.
Typically used to identify a non-hwaccel hardware decoder. For information about hwaccels, use avcodec_get_hw_config() instead.

This encoder can be flushed using avcodec_flush_buffers().
If this flag is not set, the encoder must be closed and reopened to ensure that no frames remain pending.

| #define AV_CODEC_PROP_REORDER (1 << 3) |
Codec supports frame reordering.
That is, the coded order (the order in which the encoded packets are output by the encoders / stored / input to the decoders) may be different from the presentation order of the corresponding frames.
For codecs that do not have this property set, PTS and DTS should always be equal.

| AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX | The codec supports this format via the hw_device_ctx interface. When selecting this format, AVCodecContext.hw_device_ctx should have been set to a device of the specified type before calling avcodec_open2(). |
| AV_CODEC_HW_CONFIG_METHOD_HW_FRAMES_CTX | The codec supports this format via the hw_frames_ctx interface. When selecting this format for a decoder, AVCodecContext.hw_frames_ctx should be set to a suitable frames context inside the get_format() callback. The frames context must have been created on a device of the specified type. When selecting this format for an encoder, AVCodecContext.hw_frames_ctx should be set to the context which will be used for the input frames before calling avcodec_open2(). |
| AV_CODEC_HW_CONFIG_METHOD_INTERNAL | The codec supports this format by some internal method. This format can be selected without any additional configuration - no device or frames context is required. |
| AV_CODEC_HW_CONFIG_METHOD_AD_HOC | The codec supports this format by some ad-hoc method. Additional settings and/or function calls are required. See the codec-specific documentation for details. (Methods requiring this sort of configuration are deprecated and others should be used in preference.) |
| 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.

Fill the codec context based on the values from the supplied codec parameters.
Any allocated fields in codec that have a corresponding field in par are freed and replaced with duplicates of the corresponding field in par. Fields in codec that do not have a counterpart in par are not touched.

| int avcodec_open2 | ( | AVCodecContext * | avctx, |

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 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() with a non-NULL codec. Subsequent calls will do nothing.

Submit a packet for filtering.
After sending each packet, the filter must be completely drained by calling av_bsf_receive_packet() repeatedly until it returns AVERROR(EAGAIN) or AVERROR_EOF.
| pkt | the packet to filter. The bitstream filter will take ownership of the packet and reset the contents of pkt. pkt is not touched if an error occurs. If pkt is empty (i.e. NULL, or pkt->data is NULL and pkt->side_data_elems zero), it signals the end of the stream (i.e. no more non-empty packets will be sent; sending more empty packets does nothing) and will cause the filter to output any packets it may have buffered internally. |
