Member Function Documentation

init()

void Demuxer::init ( double  position, double  duration, bool  trickmode, bool  resetBasePTS  )

inline

Initialize demux.

Parameters

[in]	position	start position
[in]	duration	duration
[in]	trickmode	true if trickmode
[in]	resetBasePTS	true to reset base pts used for restamping

Definition at line 351 of file tsprocessor.cpp.

setBasePTS()

void Demuxer::setBasePTS ( unsigned long long  basePTS, bool  isFinal  )

inline

Set base PTS used for re-stamping.

Parameters

[in]	basePTS	new base PTS
[in]	final	true if base PTS is finalized

Definition at line 406 of file tsprocessor.cpp.

getBasePTS()

inline

Get base PTS used for re-stamping.

Return values

base	PTS used for re-stamping

Definition at line 420 of file tsprocessor.cpp.

processPacket()

void Demuxer::processPacket ( unsigned char *  packetStart, bool &  basePtsUpdated, bool &  ptsError, bool &  isPacketIgnored, bool  applyOffset  )

inline

Process a TS packet.

Parameters

[in]	packetStart	start of buffer containing packet
[out]	basePtsUpdated	true if base PTS is updated
[in]	ptsError	true if encountered PTS error.
