IAMTimecodeReader::put_VITCLine 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 put_VITCLine method specifies the vertical interval line that the timecode reader will use to read timecode.
This method is not implemented.
Syntax
HRESULT put_VITCLine(
[in] long Line
);
Parameters
[in] Line
Vertical line containing timecode information (valid lines are 11-20; 0 means autoselect).
Return value
Returns E_NOTIMPL.
Remarks
If VITC mode is specified in the IAMTimecodeReader::SetTCRMode method, you must specify which line or lines will contain timecode information. To read VITC on specific multiple lines, the caller would make successive calls to IAMTimecodeReader::put_VITCLine, once for each line desired.
Set the high bit to add to the list of lines for readers that test across multiple lines.
