| #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.

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. |
