| Language | Syntax |
|---|---|
| C | HRESULT IltmmAnalogVideoDecoder_put_VCRHorizontalLocking(pAnVidDec, pVal) |
| C++ | HRESULT put_VCRHorizontalLocking(newVal) |
Pointer to an IltmmAnalogVideoDecoder interface.
Value that indicates the source of the video. Possible values are:
| Value | Meaning |
|---|---|
| VARIANT_FALSE | The video is from a broadcast source. |
| VARIANT_TRUE | The video is from a tape source. |
| Value | Meaning |
|---|---|
| S_OK | The function was successful. |
| <> S_OK | An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation. |
Call IltmmAnalogVideoDecoder::get_VCRHorizontalLocking to retrieve the current video source type.
The timing accuracy of synchronization pulses is typically poorer from a tape source than from a broadcast source. Setting the value to VARIANT_TRUE tells the decoder to relax its standards, which provides a better chance of maintaining sync.
For more detailed information, refer to the Microsoft documentation for IAMAnalogVideoDecoder::put_VCRHorizontalLocking.
Win32, x64.
