Seek to a given timestamp relative to some component stream.
Only meaningful if using a network streaming protocol (e.g. MMS.).
@param h IO context from which to call the seek function pointers
@param 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.
@param timestamp timestamp in AVStream.time_base units
or if there is no stream specified then in AV_TIME_BASE units.
@param 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.
@return >= 0 on success
