Detailed Description

Buffered I/O operations.

Definition in file avio.h.

Macro Definition Documentation

#define AVIO_FLAG_DIRECT 0x8000

Use direct mode.

avio_read and avio_write should if possible be satisfied directly instead of going through a buffer, and avio_seek will always call the underlying seek function directly.

Definition at line 359 of file avio.h.

Referenced by ffio_fdopen().

#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.

Seeking works like for a local file.

Definition at line 38 of file avio.h.

Referenced by ffio_fdopen(), and ffio_init_context().

#define AVSEEK_FORCE 0x20000

Oring this flag as into the "whence" parameter to a seek function causes it to seek by any means (like reopening and linear reading) or other normally unreasonable means that can be extremely slow.

This may be ignored by the seek code.

Definition at line 230 of file avio.h.

Referenced by avio_seek(), and ffurl_seek().

#define AVSEEK_SIZE 0x10000

Passing this as the "whence" parameter to a seek function causes it to return the filesize without seeking anywhere.

Supporting this is optional. If it is not supported then the seek function will return <0.

Typedef Documentation

typedef struct AVIOContext AVIOContext

Bytestream IO Context.

New fields can be added to the end with minor version bumps. Removal, reordering and changes to existing fields require a major version bump. sizeof(AVIOContext) must not be used outside libav*.

Note: None of the function pointers in AVIOContext should be called directly, they should only be set by the client application when implementing custom I/O. Normally these are set to the function pointers specified in avio_alloc_context()

typedef struct AVIOInterruptCB AVIOInterruptCB

Callback for checking whether to abort blocking functions.

AVERROR_EXIT is returned in this case by the interrupted function. During blocking operations, callback is called with opaque as parameter. If the callback returns 1, the blocking operation will be aborted.

No members can be added to this struct without a major bump, if new elements have been added after this struct in AVFormatContext or AVIOContext.

Function Documentation

AVIOContext* avio_alloc_context	(	unsigned char *	buffer,
		int	buffer_size,
		int	write_flag,
		void *	opaque,
		int()(void opaque, uint8_t *buf, int buf_size)	read_packet,
		int()(void opaque, uint8_t *buf, int buf_size)	write_packet,
		int64_t()(void opaque, int64_t offset, int whence)	seek
	)

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 avio_check	(	const char *	url,
		int	flags
	)

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.

Note: This function is intrinsically unsafe, in the sense that the checked resource may change its existence or permission status from one call to another. Thus you should not trust the returned value, unless you are sure that no other processes are accessing the checked resource.

Referenced by assert_file_overwrite(), build_feed_streams(), and find_image_range().

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_close_dyn_buf	(	AVIOContext *	s,
		uint8_t **	pbuffer
	)

Return the written size and a pointer to the buffer.

The buffer must be freed with av_free(). Padding of FF_INPUT_BUFFER_PADDING_SIZE is added to the buffer.

Parameters

s	IO context
pbuffer	pointer to a byte buffer

Returns: the length of the byte buffer

int avio_closep ( AVIOContext ** s )

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().

The internal buffer is automatically flushed before closing the resource.

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

const char* avio_enum_protocols	(	void **	opaque,
		int	output
	)

Iterate through names of available protocols.

Parameters

opaque	A private pointer representing current protocol. It must be a pointer to NULL on first iteration and will be updated by successive calls to avio_enum_protocols.
output	If set to 1, iterate over output protocols, otherwise over input protocols.

Returns: A static string containing the name of current protocol or NULL

int void avio_flush ( AVIOContext * s )

Force flushing of buffered data to the output s.

Force the buffered data to be immediately written to the output, without to wait to fill the internal buffer.

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.

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
