New position, in seconds.

Returns

S_OK

The function was successful.

<> S_OK

An error occurred. Refer to the Error Codes or the HRESULT error codes in the MediaFoundation documentation.

Comments

The position specified by the Position parameter is relative to the total duration, ignoring playback rate. For example, if a source file is 10 seconds long, setting the position to 5.0 causes the object seek to the middle of the file, regardless of playback rate.

Users should call IltmfPlay::CheckSeekingCapabilities to determine if ltmfPlay_Seeking_Backward and ltmfPlay_Seeking_Forward are enabled.
