AM_RATE_ResetOnTimeDisc Property
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
Applies to Windows Vista and later.
This property queries whether the decoder resynchronizes the output time stamps to the input time stamps when the decoder receives a sample with the discontinuity flag.
This property is read/write.

| Property Set GUID | AM_KSPROPSETID_TSRateChange |
| Property ID | AM_RATE_ResetOnTimeDisc |
| Data Type | DWORD |
Remarks
This property supports smooth rate changes. If the value of this property is TRUE and the decoder receives an input sample with the AM_SAMPLE_TIMEDISCONTINUITY flag, the decoded frame should have the same time stamp as the input frame.
To retrieve the AM_SAMPLE_TIMEDISCONTINUITY flag, call IMediaSample2::GetProperties on the sample. The flag is set in the dwSampleFlags member of the AM_SAMPLE2_PROPERTIES structure.
