Buffered I/O operations
Definition in file avio.h.
| #define AVIO_SEEKABLE_NORMAL (1 << 0) |
| #define AVIO_SEEKABLE_TIME (1 << 1) |
Seeking by timestamp with avio_seek_time() is possible.
| #define AVSEEK_SIZE 0x10000 |
| #define AVSEEK_FORCE 0x20000 |
| #define avio_print | ( | s, | |
| ... | |||
| ) | avio_print_string_array(s, (const char*[]){__VA_ARGS__, NULL}) |
Write strings (const char *) to the context.
This is a convenience macro around avio_print_string_array and it automatically creates the string array from the variable argument list. For simple string concatenations this function is more performant than using avio_printf since it does not need a temporary buffer.
| #define AVIO_FLAG_READ 1 |
| #define AVIO_FLAG_WRITE 2 |
write-only
| #define AVIO_FLAG_READ_WRITE (AVIO_FLAG_READ|AVIO_FLAG_WRITE) |
| #define AVIO_FLAG_NONBLOCK 8 |
Use non-blocking mode.
If this flag is set, operations on the context will return AVERROR(EAGAIN) if they can not be performed immediately. If this flag is not set, operations on the context will never return AVERROR(EAGAIN). Note that this flag does not affect the opening/connecting of the context. Connecting a protocol will always block if necessary (e.g. on network protocols) but never hang (e.g. on busy devices). Warning: non-blocking protocols is work-in-progress; this flag may be silently ignored.
| #define AVIO_FLAG_DIRECT 0x8000 |
| enum AVIODirEntryType |
| enum AVIODataMarkerType |
Different data types that can be returned via the AVIO write_data_type callback.
| Enumerator | |
|---|---|
| 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, should give decodeable results. |
| AVIO_DATA_MARKER_BOUNDARY_POINT | A point in the output bytestream where a demuxer can start parsing (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 any positions at all, it can be an actual boundary/sync point that the muxer chooses not to mark, or a later part of a packet/fragment that is cut into multiple write callbacks due to limited IO buffer size. |
| AVIO_DATA_MARKER_TRAILER | Trailer data, which doesn't contain actual content, but only for finalizing the output file. |
| AVIO_DATA_MARKER_FLUSH_POINT | A point in the output bytestream where the underlying AVIOContext might flush the buffer depending on latency or buffering requirements. Typically means the end of a packet. |
| const char* avio_find_protocol_name | ( | const char * | url | ) |
Return the name of the protocol that will handle the passed URL.
NULL is returned if no protocol could be found for the given URL.

Return AVIO_FLAG_* access flags corresponding to the access permissions of the resource in url, or a negative value corresponding to an AVERROR code in case of failure.
The returned access flags are masked by the value in flags.

| int avio_open_dir | ( | AVIODirContext ** | s, |

Open directory for reading.

Allocate and initialize an AVIOContext for buffered I/O.
It must be later freed with avio_context_free().
| buffer | Memory block for input/output operations via AVIOContext. The buffer must be allocated with av_malloc() and friends. It may be freed and replaced with a new buffer by libavformat. AVIOContext.buffer holds the buffer currently in use, which must be later freed with av_free(). |
| buffer_size | The buffer size is very important for performance. For protocols with fixed blocksize it should be set to this blocksize. For others a typical size is a cache page, e.g. 4kb. |
| write_flag | Set to 1 if the buffer should be writable, 0 otherwise. |
| opaque | An opaque pointer to user-specific data. |
| read_packet | A function for refilling the buffer, may be NULL. For stream protocols, must never return 0 but rather a proper AVERROR code. |
| write_packet | A function for writing the buffer contents, may be NULL. The function may not change the input buffers content. |
| seek | A function for seeking to specified byte position, may be NULL. |

Force flushing of buffered data.
For write streams, force the buffered data to be immediately written to the output, without to wait to fill the internal buffer.
For read streams, discard all currently buffered data, and advance the reported file position to that of the underlying stream. This does not read new data, and does not perform any seeks.

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.

Read a string from pb into buf.
The reading will terminate when either a NULL character was encountered, maxlen bytes have been read, or nothing 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.

Seek to a given timestamp relative to some component stream.
Only meaningful if using a network streaming protocol (e.g. MMS.).
| h | IO context from which to call the seek function pointers |
| stream_index | The stream index that the timestamp is relative to. If stream_index is (-1) the timestamp should be in AV_TIME_BASE units from the beginning of the presentation. If a stream_index >= 0 is used and the protocol does not support seeking based on component streams, the call will fail. |
| timestamp | timestamp in AVStream.time_base units or if there is no stream specified then in AV_TIME_BASE units. |
| flags | Optional combination of AVSEEK_FLAG_BACKWARD, AVSEEK_FLAG_BYTE and AVSEEK_FLAG_ANY. The protocol may silently ignore AVSEEK_FLAG_BACKWARD and AVSEEK_FLAG_ANY, but AVSEEK_FLAG_BYTE will fail if used and not supported. |

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.
| c | the client context to perform the handshake on |
