	)

Allocate and initialize an AVIOContext for buffered I/O.

It must be later freed with av_free().

Parameters

buffer	Memory block for input/output operations via AVIOContext. The buffer must be allocated with av_malloc() and friends.
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.
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.

Returns: Allocated AVIOContext or NULL on failure.

int ff_get_line	(	AVIOContext *	s,
		char *	buf,
		int	maxlen
	)

Read a whole line of text from AVIOContext.

Stop reading after reaching either a \n, a \0 or EOF. The returned string is always \0-terminated, and may be truncated if the buffer is too small.

Parameters

s	the read-only AVIOContext
buf	buffer to store the read line
maxlen	size of the buffer

Returns: the length of the string written in the buffer, not including the final \0

int avio_get_str	(	AVIOContext *	pb,
		int	maxlen,
		char *	buf,
		int	buflen
	)

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.

Returns: number of bytes read (is always <= maxlen). If reading ends on EOF or error, the return value will be one more than bytes actually read.

int ffio_fdopen	(	AVIOContext **	s,

Create and initialize a AVIOContext for accessing the resource referenced by the URLContext h.

Note: When the URLContext h has been opened in read+write mode, the AVIOContext can be used only for writing.

Parameters

s	Used to return the pointer to the created AVIOContext. In case of failure the pointed to value is set to NULL.

Returns: 0 in case of success, a negative value corresponding to an AVERROR code in case of failure

int ffio_rewind_with_probe_data	(	AVIOContext *	s,

	)

Rewind the AVIOContext using the specified buffer containing the first buf_size bytes of the file.

Used after probing to avoid seeking. Joins buf and s->buffer, taking any overlap into consideration.

Note: s->buffer must overlap with buf or they can't be joined and the function fails

Parameters

s	The read-only AVIOContext to rewind
buf	The probe buffer containing the first buf_size bytes of the file
buf_size	The size of buf

Returns: 0 in case of success, a negative value corresponding to an AVERROR code in case of failure

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.

Parameters

s	Used to return the pointer to the created AVIOContext. In case of failure the pointed to value is set to NULL.
flags	flags which control how the resource indicated by url is to be opened

Returns: 0 in case of success, a negative value corresponding to an AVERROR code in case of failure

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.

Parameters

s	Used to return the pointer to the created AVIOContext. In case of failure the pointed to value is set to NULL.
flags	flags which control how the resource indicated by url is to be opened
int_cb	an interrupt callback to be used at the protocols level
options	A dictionary filled with protocol-private options. On return this parameter will be destroyed and replaced with a dict containing options that were not found. May be NULL.

int avio_close ( AVIOContext * s )

Close the resource accessed by the AVIOContext s and free it.

This function can only be used if s was opened by avio_open().

The internal buffer is automatically flushed before closing the resource.

Returns: 0 on success, an AVERROR < 0 on error.

int avio_pause	(	AVIOContext *	h,

int64_t avio_seek_time	(	AVIOContext *	h,
		int	stream_index,
		int64_t	timestamp,
		int	flags
	)

Seek to a given timestamp relative to some component stream.

Only meaningful if using a network streaming protocol (e.g. MMS.).

Parameters

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.

Returns: >= 0 on success
