Takes the user-supplied byte range and scans for transport fragment boundaries.

Language | Syntax |
---|---|
C | HRESULT ILMDVRSource_GetTimedFragmentAlignment(pILMDVRSource, startOffset, endOffset, timeThreshold, pAlignedStartOffset, pAlignedEndOffset, pAlignedDuration) |
C++ | HRESULT GetTimedFragmentAlignment(startOffset, endOffset, timeThreshold, pAlignedStartOffset, pAlignedEndOffset, pAlignedDuration) |
Pointer to an ILMDVRSource interface.
(input) Specifies the byte offset at which to begin scanning for transport fragments.
(input) Specifies the byte offset at which to stop scanning for transport fragments.
(input) Specifies the byte offset at which to stop scanning for transport fragments.
(output) A pointer to a double variable, storing the offset of the start of the first transport fragment found.
(output) A pointer to a double variable, storing the offset of the end of the last transport fragment.
(output) A pointer to a double variable, storing the time (in seconds), of the transport fragments found.
Value | Meaning |
---|---|
S_OK | No error. |
S_FALSE | No transport fragment found: pAlignedStartOffset and pAlignedEndOffset are equal to startOffset, and indicate an empty search. |
Use this function along with ILMDVRSource::CopyBufferToFile to save a completely intact MPEG transport fragment.
Set up the MPEG multiplexer used for recording to DVR by calling put_OutputType(Mpg2MxT_OutputType_HLS). Doing so guarantees that fragment boundaries start with synchronization frames. Specify the boundary time interval by calling put_ResyncInterval(intervalTime).
Win32, x64.
