Module avformat Copy item path Source AVBPrint @} AVBuffer AVBufferPool AVBufferRef A reference to a data buffer. 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. AVChannelCustom An AVChannelCustom defines a single channel within a custom order layout AVChannelLayout An AVChannelLayout holds information about the channel layout of audio data. AVChapter AVClass Describe the class of an AVClass context structure. That is an
arbitrary struct of which the first field is a pointer to an
AVClass struct (e.g. AVCodecContext, AVFormatContext etc.). AVCodec AVCodec. AVCodecHWConfig AVCodecParameters This struct describes the properties of an encoded stream. AVCodecParserContext AVCodecTag AVDictionary AVDictionaryEntry @} AVFormatContext Format I/O context.
New fields can be added to the end with minor version bumps.
Removal, reordering and changes to existing fields require a major
version bump.
sizeof(AVFormatContext) must not be used outside libav*, use
avformat_alloc_context() to create an AVFormatContext. AVFrame This structure describes decoded (raw) audio or video data. AVFrameSideData Structure to hold side data for an AVFrame. AVHWDeviceContext This struct aggregates all the (hardware/vendor-specific) “high-level” state,
i.e. state that is not tied to a concrete processing configuration.
E.g., in an API that supports hardware-accelerated encoding and decoding,
this struct will (if possible) wrap the state that is common to both encoding
and decoding and from which specific instances of encoders or decoders can be
derived. AVHWFramesConstraints This struct describes the constraints on hardware frames attached to
a given device with a hardware-specific configuration. This is returned
by av_hwdevice_get_hwframe_constraints() and must be freed by
av_hwframe_constraints_free() after use. AVHWFramesContext This struct describes a set or pool of “hardware” frames (i.e. those with
data not located in normal system memory). All the frames in the pool are
assumed to be allocated in the same way and interchangeable. AVIAMFAudioElement AVIAMFMixPresentation AVIOContext Bytestream IO Context.
New public fields can be added with minor version bumps.
Removal, reordering and changes to existing public fields require
a major version bump.
sizeof(AVIOContext) must not be used outside libav*. AVIODirContext AVIODirEntry Describes single entry of the directory. AVIOInterruptCB Callback for checking whether to abort blocking functions.
AVERROR_EXIT is returned in this case by the interrupted
function. During blocking operations, callback is called with
opaque as parameter. If the callback returns 1, the
blocking operation will be aborted. AVIndexEntry AVInputFormat @addtogroup lavf_decoding
@{ AVOption a pointer to the first option specified in the class if any or NULL AVOptionRanges AVOutputFormat @addtogroup lavf_encoding
@{ 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 This structure stores auxiliary information for decoding, presenting, or
otherwise processing the coded stream. It is typically exported by demuxers
and encoders and can be fed to decoders and muxers either in a per packet
basis, or as global side data (applying to the entire coded stream). AVPanScan Pan Scan area.
This specifies the area which should be displayed.
Note there may be multiple such areas for one frame. AVProbeData This structure contains the data a format has to probe a file. AVProducerReferenceTime This structure supplies correlation between a packet timestamp and a wall clock
production time. The definition follows the Producer Reference Time (‘prft’)
as defined in ISO/IEC 14496-12 AVProfile AVProfile. AVProgram New fields can be added to the end with minor version bumps.
Removal, reordering and changes to existing fields require a major
version bump.
sizeof(AVProgram) must not be used outside libav*. AVRational Rational number (pair of numerator and denominator). AVRegionOfInterest Structure describing a single Region Of Interest. AVSideDataDescriptor This struct describes the properties of a side data type. Its instance
corresponding to a given type can be obtained from av_frame_side_data_desc(). AVStream Stream 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.
sizeof(AVStream) must not be used outside libav*. AVStreamGroup AVStreamGroupTileGrid AVStreamGroupTileGrid holds information on how to combine several
independent images on a single canvas for presentation. AVStreamGroupTileGrid__bindgen_ty_1 An @ref nb_tiles sized array of offsets in pixels from the topleft edge
of the canvas, indicating where each stream should be placed.
It must be allocated with the av_malloc() family of functions. _IO_FILE __BindgenBitfieldUnit __locale_struct __wasi_ciovec_t A region of memory for scatter/gather writes. __wasi_dirent_t A directory entry. __wasi_event_fd_readwrite_t The contents of an event when type is eventtype::fd_read or
eventtype::fd_write. __wasi_event_t An event that occurred. __wasi_fdstat_t File descriptor attributes. __wasi_filestat_t File attributes. __wasi_iovec_t A region of memory for scatter/gather reads. __wasi_prestat_dir_t The contents of a $prestat when type is preopentype::dir. __wasi_prestat_t __wasi_subscription_clock_t The contents of a subscription when type is eventtype::clock. __wasi_subscription_fd_readwrite_t The contents of a subscription when type is type is

spherical harmonics. Each channel corresponds to a single expansion
component. Channels are ordered according to ACN (Ambisonic Channel
Number). AVChannelOrder_AV_CHANNEL_ORDER_CUSTOM The channel order does not correspond to any other predefined order and
is stored as an explicit map. For example, this could be used to support
layouts with 64 or more channels, or with empty/skipped (AV_CHAN_UNUSED)
channels at arbitrary positions. AVChannelOrder_AV_CHANNEL_ORDER_NATIVE The native channel order, i.e. the channels are in the same order in
which they are defined in the AVChannel enum. This supports up to 63
different channels. AVChannelOrder_AV_CHANNEL_ORDER_UNSPEC Only the channel count is specified, without any further information
about the channel order. AVChannelOrder_FF_CHANNEL_ORDER_NB Number of channel orders, not part of ABI/API AVChannel_AV_CHAN_AMBISONIC_BASE Range of channels between AV_CHAN_AMBISONIC_BASE and
AV_CHAN_AMBISONIC_END represent Ambisonic components using the ACN system. AVChannel_AV_CHAN_AMBISONIC_END Range of channels between AV_CHAN_AMBISONIC_BASE and
AV_CHAN_AMBISONIC_END represent Ambisonic components using the ACN system.

The size of the array should match that returned by args_sizes_get.
Each argument is expected to be \0 terminated. __wasi_args_sizes_get ⚠ Return command-line argument data sizes.
@return
Returns the number of arguments and the size of the argument string
data, or an error. __wasi_clock_res_get ⚠ Return the resolution of a clock.
Implementations are required to provide a non-zero value for supported clocks. For unsupported clocks,
return errno::inval.
Note: This is similar to clock_getres in POSIX.
@return
The resolution of the clock, or an error if one happened. __wasi_clock_time_get ⚠ Return the time value of a clock.
Note: This is similar to clock_gettime in POSIX.
@return
The time value of the clock. __wasi_environ_get ⚠ Read environment variable data.
The sizes of the buffers should match that returned by environ_sizes_get.
Key/value pairs are expected to be joined with =s, and terminated with \0s. __wasi_environ_sizes_get ⚠ Return environment variable data sizes.
@return
Returns the number of environment variable arguments and the size of the
environment variable data. __wasi_fd_advise ⚠ Provide file advisory information on a file descriptor.
Note: This is similar to posix_fadvise in POSIX. __wasi_fd_allocate ⚠ Force the allocation of space in a file.
Note: This is similar to posix_fallocate in POSIX. __wasi_fd_close ⚠ Close a file descriptor.
Note: This is similar to close in POSIX. __wasi_fd_datasync ⚠ Synchronize the data of a file to disk.
Note: This is similar to fdatasync in POSIX. __wasi_fd_fdstat_get ⚠ Get the attributes of a file descriptor.
Note: This returns similar flags to fsync(fd, F_GETFL) in POSIX, as well as additional fields.
@return
The buffer where the file descriptor’s attributes are stored. __wasi_fd_fdstat_set_flags ⚠ Adjust the flags associated with a file descriptor.
Note: This is similar to fcntl(fd, F_SETFL, flags) in POSIX. __wasi_fd_fdstat_set_rights ⚠ Adjust the rights associated with a file descriptor.
This can only be used to remove rights, and returns errno::notcapable if called in a way that would attempt to add rights __wasi_fd_filestat_get ⚠ Return the attributes of an open file.
@return
The buffer where the file’s attributes are stored. __wasi_fd_filestat_set_size ⚠ Adjust the size of an open file. If this increases the file’s size, the extra bytes are filled with zeros.
Note: This is similar to ftruncate in POSIX. __wasi_fd_filestat_set_times ⚠ Adjust the timestamps of an open file or directory.
Note: This is similar to futimens in POSIX. __wasi_fd_pread ⚠ Read from a file descriptor, without using and updating the file descriptor’s offset.
Note: This is similar to preadv in POSIX.
@return
The number of bytes read. __wasi_fd_prestat_dir_name ⚠ Return a description of the given preopened file descriptor. __wasi_fd_prestat_get ⚠ Return a description of the given preopened file descriptor.

The number of bytes written. __wasi_fd_read ⚠ Read from a file descriptor.
Note: This is similar to readv in POSIX.
@return
The number of bytes read. __wasi_fd_readdir ⚠ Read directory entries from a directory.
When successful, the contents of the output buffer consist of a sequence of
directory entries. Each directory entry consists of a dirent object,
followed by dirent::d_namlen bytes holding the name of the directory
entry.
This function fills the output buffer as much as possible, potentially
truncating the last directory entry. This allows the caller to grow its
read buffer size in case it’s too small to fit a single large directory
entry, or skip the oversized directory entry.
@return
The number of bytes stored in the read buffer. If less than the size of the read buffer, the end of the directory has been reached. __wasi_fd_renumber ⚠ Atomically replace a file descriptor by renumbering another file descriptor.
Due to the strong focus on thread safety, this environment does not provide
a mechanism to duplicate or renumber a file descriptor to an arbitrary
number, like dup2(). This would be prone to race conditions, as an actual
file descriptor with the same number could be allocated by a different
thread at the same time.
This function provides a way to atomically renumber file descriptors, which
would disappear if dup2() were to be removed entirely. __wasi_fd_seek ⚠ Move the offset of a file descriptor.
Note: This is similar to lseek in POSIX.
@return
The new offset of the file descriptor, relative to the start of the file. __wasi_fd_sync ⚠ Synchronize the data and metadata of a file to disk.
Note: This is similar to fsync in POSIX. __wasi_fd_tell ⚠ Return the current offset of a file descriptor.
Note: This is similar to lseek(fd, 0, SEEK_CUR) in POSIX.
@return
The current offset of the file descriptor, relative to the start of the file. __wasi_fd_write ⚠ Write to a file descriptor.
Note: This is similar to writev in POSIX. __wasi_path_create_directory ⚠ Create a directory.
Note: This is similar to mkdirat in POSIX. __wasi_path_filestat_get ⚠ Return the attributes of a file or directory.
Note: This is similar to stat in POSIX.

The buffer where the file’s attributes are stored. __wasi_path_filestat_set_times ⚠ Adjust the timestamps of a file or directory.
Note: This is similar to utimensat in POSIX. __wasi_path_link ⚠ Create a hard link.
Note: This is similar to linkat in POSIX. __wasi_path_open ⚠ Open a file or directory.
The returned file descriptor is not guaranteed to be the lowest-numbered
file descriptor not currently open; it is randomized to prevent
applications from depending on making assumptions about indexes, since this
is error-prone in multi-threaded contexts. The returned file descriptor is
guaranteed to be less than 2**31.
Note: This is similar to openat in POSIX.
@return
The file descriptor of the file that has been opened. __wasi_path_readlink ⚠ Read the contents of a symbolic link.
Note: This is similar to readlinkat in POSIX.
@return
The number of bytes placed in the buffer. __wasi_path_remove_directory ⚠ Remove a directory.
Return errno::notempty if the directory is not empty.
Note: This is similar to unlinkat(fd, path, AT_REMOVEDIR) in POSIX. __wasi_path_rename ⚠ Rename a file or directory.
Note: This is similar to renameat in POSIX. __wasi_path_symlink ⚠ Create a symbolic link.
Note: This is similar to symlinkat in POSIX. __wasi_path_unlink_file ⚠ Unlink a file.
Return errno::isdir if the path refers to a directory.
Note: This is similar to unlinkat(fd, path, 0) in POSIX. __wasi_poll_oneoff ⚠ Concurrently poll for the occurrence of a set of events.
@return
The number of events stored. __wasi_proc_exit ⚠ Terminate the process normally. An exit code of 0 indicates successful
termination of the program. The meanings of other values is dependent on
the environment. __wasi_random_get ⚠ Write high-quality random data into a buffer.
This function blocks when the implementation is unable to immediately
provide sufficient high-quality random data.
This function may execute slowly, so when large mounts of random data are
required, it’s advisable to use this function to seed a pseudo-random
number generator, rather than to provide the random data directly. __wasi_sched_yield ⚠ Temporarily yield execution of the calling thread.
Note: This is similar to sched_yield in POSIX. __wasi_sock_accept ⚠ Accept a new incoming connection.
Note: This is similar to accept in POSIX.
@return
New socket connection __wasi_sock_recv ⚠ Receive a message from a socket.
Note: This is similar to recv in POSIX, though it also supports reading
the data into multiple buffers in the manner of readv.
@return
Number of bytes stored in ri_data and message flags. __wasi_sock_send ⚠ Send a message on a socket.
Note: This is similar to send in POSIX, though it also supports writing
the data from multiple buffers in the manner of writev.
@return
Number of bytes transmitted. __wasi_sock_shutdown ⚠ Shut down socket send and receive channels.
Note: This is similar to shutdown in POSIX. a64l ⚠ abort ⚠ abs ⚠ acos ⚠ acosf ⚠ acosh ⚠ acoshf ⚠ acoshl ⚠ acosl ⚠ aligned_alloc ⚠ alloca ⚠ arc4random ⚠ arc4random_buf ⚠ arc4random_uniform ⚠ asin ⚠ asinf ⚠ asinh ⚠ asinhf ⚠ asinhl ⚠ asinl ⚠ asprintf ⚠ at_quick_exit ⚠ atan ⚠ atan2 ⚠ atan2f ⚠ atan2l ⚠ atanf ⚠ atanh ⚠ atanhf ⚠ atanhl ⚠ atanl ⚠ atexit ⚠ atof ⚠ atoi ⚠ atol ⚠ atoll ⚠ av_add_index_entry ⚠ Add an index entry into a sorted list. Update the entry if the list
already contains it. av_add_q ⚠ Add two rationals.
@param b First rational
@param c Second rational
@return b+c av_add_stable ⚠ Add a value to a timestamp. av_append_packet ⚠ Read data and append it to the current content of the AVPacket.
If pkt->size is 0 this is identical to av_get_packet.
Note that this uses av_grow_packet and thus involves a realloc
which is inefficient. Thus this function should only be used
when there is no reasonable way to know (an upper bound of)
the final size. av_bessel_i0 ⚠ 0th order modified bessel function of the first kind. av_buffer_alloc ⚠ Allocate an AVBuffer of the given size using av_malloc(). av_buffer_allocz ⚠ Same as av_buffer_alloc(), except the returned buffer will be initialized
to zero. av_buffer_create ⚠ Create an AVBuffer from an existing array. av_buffer_default_free ⚠ Default free callback, which calls av_free() on the buffer data.
This function is meant to be passed to av_buffer_create(), not called
directly. av_buffer_get_opaque ⚠ @return the opaque parameter set by av_buffer_create. av_buffer_get_ref_count ⚠ av_buffer_is_writable ⚠ @return 1 if the caller may write to the data referred to by buf (which is
true if and only if buf is the only reference to the underlying AVBuffer).
Return 0 otherwise.
A positive answer is valid until av_buffer_ref() is called on buf. av_buffer_make_writable ⚠ Create a writable reference from a given buffer reference, avoiding data copy
if possible. av_buffer_pool_buffer_get_opaque ⚠ Query the original opaque parameter of an allocated buffer in the pool. av_buffer_pool_get ⚠ Allocate a new AVBuffer, reusing an old buffer from the pool when available.
This function may be called simultaneously from multiple threads. av_buffer_pool_init ⚠ Allocate and initialize a buffer pool. av_buffer_pool_init2 ⚠ Allocate and initialize a buffer pool with a more complex allocator. av_buffer_pool_uninit ⚠ Mark the pool as being available for freeing. It will actually be freed only
once all the allocated buffers associated with the pool are released. Thus it
is safe to call this function while some of the allocated buffers are still
in use. av_buffer_realloc ⚠ Reallocate a given buffer. av_buffer_ref ⚠ Create a new reference to an AVBuffer. av_buffer_replace ⚠ Ensure dst refers to the same data as src. av_buffer_unref ⚠ Free a given reference and automatically free the buffer if there are no more
references to it. av_calloc ⚠ Allocate a memory block for an array with av_mallocz(). av_channel_description ⚠ Get a human readable string describing a given channel. av_channel_description_bprint ⚠ bprint variant of av_channel_description(). av_channel_from_string ⚠ This is the inverse function of @ref av_channel_name(). av_channel_layout_channel_from_index ⚠ Get the channel with the given index in a channel layout. av_channel_layout_channel_from_string ⚠ Get a channel described by the given string. av_channel_layout_check ⚠ Check whether a channel layout is valid, i.e. can possibly describe audio
data. av_channel_layout_compare ⚠ Check whether two channel layouts are semantically the same, i.e. the same
channels are present on the same positions in both. av_channel_layout_copy ⚠ Make a copy of a channel layout. This differs from just assigning src to dst
in that it allocates and copies the map for AV_CHANNEL_ORDER_CUSTOM. av_channel_layout_custom_init ⚠ Initialize a custom channel layout with the specified number of channels.
The channel map will be allocated and the designation of all channels will
be set to AV_CHAN_UNKNOWN. av_channel_layout_default ⚠ Get the default channel layout for a given number of channels. av_channel_layout_describe ⚠ Get a human-readable string describing the channel layout properties.
The string will be in the same format that is accepted by
@ref av_channel_layout_from_string(), allowing to rebuild the same
channel layout, except for opaque pointers. av_channel_layout_describe_bprint ⚠ bprint variant of av_channel_layout_describe(). av_channel_layout_from_mask ⚠ Initialize a native channel layout from a bitmask indicating which channels
are present. av_channel_layout_from_string ⚠ Initialize a channel layout from a given string description.
The input string can be represented by: av_channel_layout_index_from_channel ⚠ Get the index of a given channel in a channel layout. In case multiple
channels are found, only the first match will be returned. av_channel_layout_index_from_string ⚠ Get the index in a channel layout of a channel described by the given string.
In case multiple channels are found, only the first match will be returned. av_channel_layout_retype ⚠ Change the AVChannelOrder of a channel layout. av_channel_layout_standard ⚠ Iterate over all standard channel layouts. av_channel_layout_subset ⚠ Find out what channels from a given set are present in a channel layout,
without regard for their positions. av_channel_layout_uninit ⚠ Free any allocated data in the channel layout and reset the channel
count to 0. av_channel_name ⚠ Get a human readable string in an abbreviated form describing a given channel.

If no codec id is found returns AV_CODEC_ID_NONE. av_codec_get_tag ⚠ Get the codec tag for the given codec id id.
If no codec tag is found returns 0. av_codec_get_tag2 ⚠ Get the codec tag for the given codec id. av_codec_is_decoder ⚠ @return a non-zero number if codec is a decoder, zero otherwise av_codec_is_encoder ⚠ @return a non-zero number if codec is an encoder, zero otherwise av_codec_iterate ⚠ Iterate over all registered codecs. av_compare_mod ⚠ Compare the remainders of two integer operands divided by a common divisor. av_compare_ts ⚠ Compare two timestamps each in its own time base. av_cpb_properties_alloc ⚠ Allocate a CPB properties structure and initialize its fields to default
values. av_d2q ⚠ Convert a double precision floating point number to a rational. av_default_get_category ⚠ av_default_item_name ⚠ Return the context name av_demuxer_iterate ⚠ Iterate over all registered demuxers. av_dict_copy ⚠ Copy entries from one AVDictionary struct into another. av_dict_count ⚠ Get number of entries in dictionary. av_dict_free ⚠ Free all the memory allocated for an AVDictionary struct
