IAMTimecodeDisplay::SetTCDisplayEnable 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetTCDisplayEnable method enables or disables an external device's timecode character output generator.
Syntax

[in] long State
);
Parameters
[in] State
Value specifying whether to enable or disable the timecode character output generator. Specify OATRUE to enable or OAFALSE to disable.
Return value
Returns an HRESULT value that depends on the implementation of the interface.
Remarks
This method is not intended for rendering characters 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.
