#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.

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.
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().

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

const char* avio_enum_protocols ( void **  opaque,

)

Iterate through names of available protocols.

Note:
it is recommanded to use av_protocol_next() instead of this
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.

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 avio_get_str16le ( AVIOContext *  pb,

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

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

attribute_deprecated void avio_set_interrupt_cb ( int(*)(void)  interrupt_cb  ) 

The callback is called in blocking functions to test regulary if asynchronous interruption is needed.

AVERROR_EXIT is returned in this case by the interrupted function. 'NULL' means no interrupt callback is given.

Deprecated:
Use interrupt_callback in AVFormatContext/avio_open2 instead.
