См. определение в файле avcodec.h строка 3481
◆ name
| const char* AVCodec::name |
Name of the codec implementation. The name is globally unique among encoders and among decoders (but an encoder and a decoder can share the same name). This is the primary way to find a codec from the user perspective.
См. определение в файле avcodec.h строка 3488
◆ long_name
| const char* AVCodec::long_name |
Descriptive name for the codec, meant to be more human readable than name. You should use the NULL_IF_CONFIG_SMALL() macro to define it.
См. определение в файле avcodec.h строка 3493
◆ type
◆ id
◆ capabilities
| int AVCodec::capabilities |
Codec capabilities. see AV_CODEC_CAP_*
См. определение в файле avcodec.h строка 3500
◆ supported_framerates
array of supported framerates, or NULL if any, array is terminated by {0,0}
См. определение в файле avcodec.h строка 3501
◆ pix_fmts
array of supported pixel formats, or NULL if unknown, array is terminated by -1
См. определение в файле avcodec.h строка 3502
◆ supported_samplerates
| const int* AVCodec::supported_samplerates |
array of supported audio samplerates, or NULL if unknown, array is terminated by 0
См. определение в файле avcodec.h строка 3503
◆ sample_fmts
array of supported sample formats, or NULL if unknown, array is terminated by -1
См. определение в файле avcodec.h строка 3504
◆ channel_layouts
| const uint64_t* AVCodec::channel_layouts |
array of support channel layouts, or NULL if unknown. array is terminated by 0
См. определение в файле avcodec.h строка 3505
◆ max_lowres
maximum value for lowres supported by the decoder
См. определение в файле avcodec.h строка 3506
◆ priv_class
◆ profiles
array of recognized profiles, or NULL if unknown, array is terminated by {FF_PROFILE_UNKNOWN}
См. определение в файле avcodec.h строка 3508
◆ wrapper_name
| const char* AVCodec::wrapper_name |
Group name of the codec implementation. This is a short symbolic name of the wrapper backing this codec. A wrapper uses some kind of external implementation for the codec, such as an external library, or a codec implementation provided by the OS or the hardware. If this field is NULL, this is a builtin, libavcodec native codec. If non-NULL, this will be the suffix in AVCodec.name in most cases (usually AVCodec.name will be of the form "<codec_name>_<wrapper_name>").
См. определение в файле avcodec.h строка 3520
◆ priv_data_size
| int AVCodec::priv_data_size |
◆ next
◆ init_thread_copy
If defined, called on thread contexts when they are created. If the codec allocates writable tables in init(), re-allocate them here. priv_data will be set to a copy of the original.
См. определение в файле avcodec.h строка 3540
◆ update_thread_context
Copy necessary context variables from a previous thread context to the current one. If not defined, the next thread will start automatically; otherwise, the codec must call ff_thread_finish_setup().
dst and src will (rarely) point to the same context, in which case memcpy should be skipped.
См. определение в файле avcodec.h строка 3548
◆ defaults
Private codec-specific defaults.
См. определение в файле avcodec.h строка 3554
◆ init_static_data
| void(* AVCodec::init_static_data) (struct AVCodec *codec) |
Initialize codec static data, called from avcodec_register().
This is not intended for time consuming operations as it is run for every codec regardless of that codec being used.
См. определение в файле avcodec.h строка 3562
◆ init
◆ encode_sub
◆ encode2
Encode data to an AVPacket.
- Аргументы
-
| avctx | codec context |
| avpkt | output AVPacket (may contain a user-provided buffer) |
| [in] | frame | AVFrame containing the raw data to be encoded |
| [out] | got_packet_ptr | encoder sets to 0 or 1 to indicate that a non-empty packet was returned in avpkt. |
- Возвращает
- 0 on success, negative error code on failure
См. определение в файле avcodec.h строка 3577
◆ decode
◆ close
◆ send_frame
Encode API with decoupled packet/frame dataflow. The API is the same as the avcodec_ prefixed APIs (avcodec_send_frame() etc.), except that:
- never called if the codec is closed or the wrong type,
- if AV_CODEC_CAP_DELAY is not set, drain frames are never sent,
- only one drain frame is ever passed down,
См. определение в файле avcodec.h строка 3589
◆ receive_packet
◆ receive_frame
Decode API with decoupled packet/frame dataflow. This function is called to get one output frame. It should call ff_decode_get_packet() to obtain input data.
См. определение в файле avcodec.h строка 3597
◆ flush
Flush buffers. Will be called when seeking
См. определение в файле avcodec.h строка 3602
◆ caps_internal
| int AVCodec::caps_internal |
Internal codec capabilities. See FF_CODEC_CAP_* in internal.h
См. определение в файле avcodec.h строка 3607
◆ bsfs
| const char* AVCodec::bsfs |
Decoding only, a comma-separated list of bitstream filters to apply to packets before decoding.
См. определение в файле avcodec.h строка 3613
◆ hw_configs
| const struct AVCodecHWConfigInternal** AVCodec::hw_configs |
Array of pointers to hardware configurations supported by the codec, or NULL if no hardware supported. The array is terminated by a NULL pointer.
The user can only access this field via avcodec_get_hw_config().
