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, returning a pointer.
Note that the data pointed at by the returned pointer is only valid until the next call that references the same IO context.
s | IO context |
buf | pointer to buffer into which to assemble the requested data if it is not available in contiguous addresses in the underlying buffer |
size | number of bytes requested |
data | address at which to store pointer: this will be a a direct pointer into the underlying buffer if the requested number of bytes are available at contiguous addresses, otherwise will be a copy of buf |

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.
