useInputTimestamps()

void ts::DurationAnalyzer::useInputTimestamps ( bool  prefer_timestamps )

inline

Select the prefered method for duration evaluation.

Parameters

[in]

prefer_timestamps

If true, use input timestamps when possible. Fallback to PCR analysis if the input timestamps are not valid or not monotonic. If false, always use PCR analysis, ignore timestamps.

		const TSPacketMetadata &	mdata
	)

The following method feeds the analyzer with a TS packet.

Parameters

[in]	pkt	A new transport stream packet.
[in]	mdata	Associated metadata, including the input timestamp.

duration()

PCR ts::DurationAnalyzer::duration ( ) const

inline
