IAMTimecodeDisplay::GetTCDisplayEnable method (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The GetTCDisplayEnable method determines whether an external device's timecode character generator output is enabled or disabled.
Syntax

[out] long *pState
);
Parameters
[out] pState
Pointer to a value indicating whether timecode character generator output is enabled. OATRUE indicates enabled; OAFALSE indicates disabled.
Return value

Remarks
This method is not intended for character rendering inside a filter graph, it is purely intended for hardware displays. Ensure that your external timecode reader or generator has display capability before trying to use this method.
