AVBufferSrcParameters

This structure contains the parameters describing the frames that will be passed to this filter.

AVCAMELLIA
AVCAST5
AVCPBProperties

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.

AVChapter
AVClass
AVCodec

AVCodec.

AVCodecContext

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*.

AVCodecDefault
AVCodecDescriptor

This struct describes the properties of a single codec described by an AVCodecID. @see avcodec_descriptor_get()

AVCodecHWConfig
AVCodecHWConfigInternal

Array of pointers to hardware configurations supported by the codec, or NULL if no hardware supported. The array is terminated by a NULL pointer.

AVCodecInternal

@}

AVCodecParameters

This struct describes the properties of an encoded stream.

AVCodecParser
AVCodecParserContext
AVCodecTag
AVComponentDescriptor
AVDVProfile
AVDeviceCapabilitiesQuery

Structure describes device capabilities.

AVDeviceInfo

Structure describes basic parameters of the device.

AVDeviceInfoList

List of devices.

AVDeviceRect
AVDictionary
AVDictionaryEntry
AVDownmixInfo

This structure describes optional metadata relevant to a downmix procedure.

AVExpr
AVFifoBuffer
AVFilter

Filter definition. This defines the pads a filter contains, and all the callback functions used to interact with the filter.

AVFilterChannelLayouts
AVFilterCommand
AVFilterContext

An instance of a filter

AVFilterFormats
AVFilterGraph
AVFilterGraphInternal
AVFilterInOut

A linked-list of the inputs/outputs of the filter chain.

AVFilterInternal
AVFilterLink

A link between two filters. This contains pointers to the source and destination filters between which this link exists, and the indexes of the pads involved. In addition, this link also contains the parameters which have been negotiated and agreed upon between the filter, such as image dimensions, format, etc.

AVHashContext

@example ffhash.c This example is a simple command line application that takes one or more arguments. It demonstrates a typical use of the hashing API with allocation, initialization, updating, and finalizing.

AVIOContext
AVIODirContext
AVIODirEntry
AVIOInterruptCB
AVIndexEntry
AVInputFormat
AVLFG

Context structure for the Lagged Fibonacci PRNG. The exact layout, types and content of this struct may change and should not be accessed directly. Only its sizeof() is guranteed to stay the same to allow easy instanciation.

AVMD5
AVMotionVector
AVMurMur3
AVOption
AVOptionRange
AVOptionRanges
AVOutputFormat
AVPacket

This structure stores compressed data. It is typically exported by demuxers and then passed as input to decoders, or received as output from encoders and then passed to muxers.

AVPacketList
AVPacketSideData
AVPanScan

Pan Scan area. This specifies the area which should be displayed. Note there may be multiple such areas for one frame.

AVPicture

Picture data structure.

AVPixFmtDescriptor

Descriptor that unambiguously describes how the bits of a pixel are stored in the up to 4 data planes of an image. It also stores the subsampling factors and number of components.

AVProbeData
AVProfile

AVProfile.

AVProgram
AVRIPEMD
AVRational
AVRegionOfInterest
AVReplayGain

ReplayGain information (see http://wiki.hydrogenaudio.org/index.php?title=ReplayGain_1.0_specification). The size of this struct is a part of the public ABI.

AVSHA
AVSHA512
AVStereo3D

Stereo 3D type: this structure describes how two videos are packed within a single video surface, with additional information as needed.

vaapi_context

This structure is used to share data between the FFmpeg library and the client video application. This shall be zero-allocated and available as AVCodecContext.hwaccel_context. All user members can be set once during initialization or through each AVCodecContext.get_buffer() function call. In any case, they must be valid prior to calling decoding functions.

Message types used by avdevice_app_to_dev_control_message().

AVAudioServiceType
AVCRCId
AVChromaLocation
AVClassCategory
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.

av_lockmgr_register

Register a user provided lock manager supporting the operations specified by AVLockOp. The "mutex" argument to the function points to a (void *) where the lockmgr should store/get a pointer to a user allocated mutex. It is NULL upon AV_LOCK_CREATE and equal to the value left by the last call for all other ops. If the lock manager is unable to perform the op then it should leave the mutex in the same state as when it was called and return a non-zero value. However, when called with AV_LOCK_DESTROY the mutex will always be assumed to have been successfully destroyed. If av_lockmgr_register succeeds it will return a non-negative value, if it fails it will return a negative value and destroy all mutex and unregister all callbacks. av_lockmgr_register is not thread-safe, it must be called from a single thread before any calls which make use of locking are used.

Set the closed field of a link. @deprecated applications are not supposed to mess with links, they should close the sinks.

avfilter_next

Iterate over all registered filters. @return If prev is non-NULL, next registered filter after prev or NULL if prev is the last filter. If prev is NULL, return the first registered filter.

avfilter_pad_count

Get the number of elements in a NULL-terminated array of AVFilterPads (e.g. AVFilter.inputs/outputs).

avfilter_pad_get_name

Get the name of an AVFilterPad.

avfilter_pad_get_type

Get the type of an AVFilterPad.

avfilter_process_command

Make the filter instance process a command. It is recommended to use avfilter_graph_send_command().

avfilter_register

Register a filter. This is only needed if you plan to use avfilter_get_by_name later to lookup the AVFilter structure by name. A filter can still by instantiated with avfilter_graph_alloc_filter even if it is not registered.

avfilter_register_all

Initialize the filter system. Register all builtin filters.

avfilter_version

Return the LIBAVFILTER_VERSION_INT constant.

swr_build_matrix

Generate a channel mixing matrix.

swr_close

Closes the context so that swr_is_initialized() returns 0.

swr_config_frame

Configure or reconfigure the SwrContext using the information provided by the AVFrames.

swr_convert

Convert audio.

swr_convert_frame

Convert the samples in the input AVFrame and write them to the output AVFrame.

Return a positive value if pix_fmt is a supported output format, 0 otherwise.

sws_normalizeVec

Scale all the coefficients of a so that their sum equals height.

sws_printVec2
sws_scale

Scale the image slice in srcSlice and put the resulting scaled slice in the image in dst. A slice is a sequence of consecutive rows in an image.

sws_scaleVec

Scale all the coefficients of a by the scalar value.

sws_setColorspaceDetails

@param dstRange flag indicating the while-black range of the output (1=jpeg / 0=mpeg) @param srcRange flag indicating the while-black range of the input (1=jpeg / 0=mpeg) @param table the yuv2rgb coefficients describing the output yuv space, normally ff_yuv2rgb_coeffs[x] @param inv_table the yuv2rgb coefficients describing the input yuv space, normally ff_yuv2rgb_coeffs[x] @param brightness 16.16 fixed point brightness correction @param contrast 16.16 fixed point contrast correction @param saturation 16.16 fixed point saturation correction @return -1 if not supported

sws_shiftVec
sws_subVec
swscale_configuration

Return the libswscale build-time configuration.

swscale_license

Return the libswscale license.
