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. |

void avio_flush | ( | AVIOContext * | s | ) |
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.

int avio_handshake | ( | AVIOContext * | c | ) |
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.
