AVIO_DATA_MARKER_HEADER Header data; this needs to be present for the stream to be decodeable. AVIO_DATA_MARKER_SYNC_POINT A point in the output bytestream where a decoder can start decoding
(i.e. a keyframe). A demuxer/decoder given the data flagged with
AVIO_DATA_MARKER_HEADER, followed by any AVIO_DATA_MARKER_SYNC_POINT,

(for non self synchronizing bytestream formats). That is, any
non-keyframe packet start point. AVIO_DATA_MARKER_UNKNOWN This is any, unlabelled data. It can either be a muxer not marking

avio_print. avio_flush ⚠ Force flushing of buffered data. avio_read ⚠ Read size bytes from AVIOContext into buf.
@return number of bytes read or AVERROR avio_read_partial ⚠ Read size bytes from AVIOContext into buf. Unlike avio_read(), this is allowed
to read fewer bytes than requested. The missing bytes can be read in the next
call. This always tries to read at least 1 byte.
Useful to reduce latency in certain cases.

more can be read from pb. The result is guaranteed to be NULL-terminated, it
will be truncated if buf is too small.
Note that the string is not interpreted or validated in any way, it
might get truncated in the middle of a sequence for multi-byte encodings. avio_get_str16le ⚠ Read a UTF-16 string from pb and convert it to UTF-8.
The reading will terminate when either a null or invalid character was
encountered or maxlen bytes have been read.
@return number of bytes read (is always <= maxlen) avio_get_str16be ⚠ avio_open ⚠ Create and initialize a AVIOContext for accessing the
resource indicated by url.
@note When the resource indicated by url has been opened in
read+write mode, the AVIOContext can be used only for writing. avio_open2 ⚠ Create and initialize a AVIOContext for accessing the
resource indicated by url.
@note When the resource indicated by url has been opened in
read+write mode, the AVIOContext can be used only for writing. avio_close ⚠ Close the resource accessed by the AVIOContext s and free it.
This function can only be used if s was opened by avio_open(). avio_closep ⚠ Close the resource accessed by the AVIOContext *s, free it
and set the pointer pointing to it to NULL.
This function can only be used if s was opened by avio_open(). avio_open_dyn_buf ⚠ Open a write only memory stream. avio_get_dyn_buf ⚠ Return the written size and a pointer to the buffer.
The AVIOContext stream is left intact.
The buffer must NOT be freed.
No padding is added to the buffer. avio_close_dyn_buf ⚠ Return the written size and a pointer to the buffer. The buffer
must be freed with av_free().
Padding of AV_INPUT_BUFFER_PADDING_SIZE is added to the buffer. avio_enum_protocols ⚠ Iterate through names of available protocols. avio_protocol_get_class ⚠ Get AVClass by names of available protocols. avio_pause ⚠ Pause and resume playing - only meaningful if using a network streaming
protocol (e.g. MMS). avio_seek_time ⚠ Seek to a given timestamp relative to some component stream.
Only meaningful if using a network streaming protocol (e.g. MMS.). avio_read_to_bprint ⚠ Read contents of h into print buffer, up to max_size bytes, or up to EOF. avio_accept ⚠ Accept and allocate a client context on a server context.
@param s the server context
@param c the client context, must be unallocated
@return >= 0 on success or a negative value corresponding
to an AVERROR on failure avio_handshake ⚠ Perform one step of the protocol handshake to accept a new client.
This function must be called on a client returned by avio_accept() before
using it as a read/write context.
It is separate from avio_accept() because it may block.
A step of the handshake is defined by places where the application may
decide to change the proceedings.
For example, on a protocol with a request header and a reply header, each
one can constitute a step because the application may use the parameters
from the request to change parameters in the reply; or each individual
chunk of the request can constitute a step.
If the handshake is already finished, avio_handshake() does nothing and
returns 0 immediately. av_get_packet ⚠ Allocate and read the payload of a packet and initialize its
fields with default values. 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. AVSTREAM_PARSE_NONE AVSTREAM_PARSE_FULL < full parsing and repack AVSTREAM_PARSE_HEADERS < Only parse headers, do not repack. AVSTREAM_PARSE_TIMESTAMPS < full parsing and interpolation of timestamps for frames not starting on a packet boundary AVSTREAM_PARSE_FULL_ONCE < full parsing and repack of the first frame only, only implemented for H.264 currently AVSTREAM_PARSE_FULL_RAW < full parsing and repack with timestamp and position generation by parser for raw

Each time a probe returns
with a score that is too low, the probe buffer size is increased and another
attempt is made. When the maximum probe size is reached, the input format
with the highest score is returned. av_probe_input_buffer ⚠ Like av_probe_input_buffer2() but returns 0 on success avformat_open_input ⚠ Open an input stream and read the header. The codecs are not opened.
The stream must be closed with avformat_close_input(). avformat_find_stream_info ⚠ Read packets of a media file to get stream information. This
is useful for file formats with no headers such as MPEG. This
function also computes the real framerate in case of MPEG-2 repeat
frame mode.
The logical file position is not changed by this function;
examined packets may be buffered for later processing. av_find_program_from_stream ⚠ Find the programs which belong to a given stream. av_program_add_stream_index ⚠ av_find_best_stream ⚠ Find the “best” stream in the file.
The best stream is determined according to various heuristics as the most
likely to be what the user expects.
If the decoder parameter is non-NULL, av_find_best_stream will find the
default decoder for the stream’s codec; streams for which no decoder can
be found are ignored. av_read_frame ⚠ Return the next frame of a stream.
This function returns what is stored in the file, and does not validate
that what is there are valid frames for the decoder. It will split what is
stored in the file into frames and return one for each call. It will not
omit invalid data between valid frames so as to give the decoder the maximum
information possible for decoding. av_seek_frame ⚠ Seek to the keyframe at timestamp.
‘timestamp’ in ‘stream_index’. avformat_seek_file ⚠ Seek to timestamp ts.
Seeking will be done so that the point from which all active streams
can be presented successfully will be closest to ts and within min/max_ts.
Active streams are all streams that have AVStream.discard < AVDISCARD_ALL. avformat_flush ⚠ Discard all internally buffered data. This can be useful when dealing with
discontinuities in the byte stream. Generally works only with formats that
can resync. This includes headerless formats like MPEG-TS/TS but should also
work with NUT, Ogg and in a limited way AVI for example. av_read_play ⚠ Start playing a network-based stream (e.g. RTSP stream) at the
current position. av_read_pause ⚠ Pause a network-based stream (e.g. RTSP stream). avformat_close_input ⚠ Close an opened input AVFormatContext. Free it and all its contents
and set *s to NULL. avformat_write_header ⚠ Allocate the stream private data and write the stream header to
an output media file. avformat_init_output ⚠ Allocate the stream private data and initialize the codec, but do not write the header.
May optionally be used before avformat_write_header() to initialize stream parameters
before actually writing the header.
If using this function, do not pass the same options to avformat_write_header(). av_write_frame ⚠ Write a packet to an output media file. av_interleaved_write_frame ⚠ Write a packet to an output media file ensuring correct interleaving. av_write_uncoded_frame ⚠ Write an uncoded frame to an output media file. av_interleaved_write_uncoded_frame ⚠ Write an uncoded frame to an output media file. av_write_uncoded_frame_query ⚠ Test whether a muxer supports uncoded frame. av_write_trailer ⚠ Write the stream trailer to an output media file and free the
file private data. av_guess_format ⚠ Return the output format in the list of registered output formats
which best matches the provided parameters, or return NULL if
there is no match. av_guess_codec ⚠ Guess the codec ID based upon muxer and filename. av_get_output_timestamp ⚠ Get timing information for the data currently output.
The exact meaning of “currently output” depends on the format.
It is mostly relevant for devices that have an internal buffer and/or
work in real time.

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). 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 AVCodecDescriptor This struct describes the properties of a single codec described by an
AVCodecID.
