Подробное описание
Basic definitions, functions for querying libavcodec capabilities, allocating core structures, etc.
Типы
◆ AVCodecDescriptor
| typedef struct AVCodecDescriptor AVCodecDescriptor |
#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>
This struct describes the properties of a single codec described by an AVCodecID.

- avcodec_descriptor_get()
◆ AVPanScan
#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>
Pan Scan area. This specifies the area which should be displayed. Note there may be multiple such areas for one frame.
◆ AVCPBProperties
| typedef struct AVCPBProperties AVCPBProperties |
#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>
This structure describes the bitrate properties of an encoded bitstream. It roughly corresponds to a subset the VBV parameters for MPEG-2 or HRD parameters for H.264/HEVC.
◆ AVCodecContext
| typedef struct AVCodecContext AVCodecContext |
#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>
main external API structure. New fields can be added to the end with minor version bumps. Removal, reordering and changes to existing fields require a major version bump. You can use AVOptions (av_opt* / av_set/get*()) to access these fields from user applications. The name string for AVOptions options matches the associated command line parameter name and can be found in libavcodec/options_table.h The AVOption/command line parameter names differ in some cases from the C structure field names for historic reasons or brevity. sizeof(AVCodecContext) must not be used outside libav*.
◆ AVProfile
◆ AVCodecHWConfig
| typedef struct AVCodecHWConfig AVCodecHWConfig |
◆ AVCodecDefault
| typedef struct AVCodecDefault AVCodecDefault |
◆ AVCodec
◆ AVSubtitleRect
| typedef struct AVSubtitleRect AVSubtitleRect |
◆ AVSubtitle
| typedef struct AVSubtitle AVSubtitle |
◆ AVCodecParameters
| typedef struct AVCodecParameters AVCodecParameters |
#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>
This struct describes the properties of an encoded stream.
sizeof(AVCodecParameters) is not a part of the public ABI, this struct must be allocated with avcodec_parameters_alloc() and freed with avcodec_parameters_free().
Перечисления
◆ AVCodecID
| enum AVCodecID |
#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>
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
- no value of an existing codec ID changes (that would break ABI),
- it is as close as possible to similar codecs
After adding new codec IDs, do not forget to add an entry to the codec descriptor list and bump libavcodec minor version.

| 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. |
| 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.) |

- Аргументы
-
codec if non-NULL, allocate private data and initialize defaults for the given codec. It is illegal to then call avcodec_open2() with a different codec. If NULL, then the codec-specific defaults won't be initialized, which may result in suboptimal default settings (this is important mainly for encoders, e.g. libx264).

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.

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.

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.
- Заметки
- Do not use this function. Use avcodec_free_context() to destroy a codec context (either open or closed). Opening and closing a codec context multiple times is not supported anymore – use multiple codec contexts instead.
