Allocate and initialize an AVIOContext for buffered I/O.
It must be later freed with av_free().
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. |

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.

int64_t avio_seek_time | ( | AVIOContext * | h, | |
int | stream_index, | |||
int64_t | timestamp, | |||

) |
Seek to a given timestamp relative to some component stream.
Only meaningful if using a network streaming protocol (e.g. MMS.).
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 with ENOTSUP. | |
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 with ENOTSUP if used and not supported. |
