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 unreasonble means that can be extreemly slow.
This may be ignored by the seek code.

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.

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. |
