Member Function Documentation

void cPatPmtGenerator::GeneratePat ( void  )
protected

Generates a PAT section for later use with GetPat().

Definition at line 527 of file remux.c.

References P_TSID, PATPID, TS_PAYLOAD_START, and TS_SYNC_BYTE.

void cPatPmtGenerator::GeneratePmt ( const cChannel Channel)
protected
void cPatPmtGenerator::GeneratePmtPid ( const cChannel Channel)
protected

Generates a PMT pid that doesn't collide with any of the actual pids of the Channel.

References cChannel::Apids(), cChannel::Dpids(), MAXPID, P_PMT_PID, cChannel::Ppid(), SETPID, SETPIDS, cChannel::Spids(), cChannel::Tpid(), and cChannel::Vpid().

uchar * cPatPmtGenerator::GetPat ( void  )

Returns a pointer to the PAT section, which consists of exactly one TS packet.

Definition at line 645 of file remux.c.

Referenced by cRecorder::Action(), and cTransfer::Activate().

uchar * cPatPmtGenerator::GetPmt ( int &  Index)

Returns a pointer to the Index'th TS packet of the PMT section.

Index must be initialized to 0 and will be incremented by each call to GetPmt(). Returns NULL is all packets of the PMT section have been fetched..

void cPatPmtGenerator::SetChannel ( const cChannel Channel)

Sets the Channel for which the PAT/PMT shall be generated.

Definition at line 636 of file remux.c.

Referenced by cRecorder::cRecorder(), and cTransfer::cTransfer().

void cPatPmtGenerator::SetVersions ( int  PatVersion,
int  PmtVersion 
)

Sets the version numbers for the generated PAT and PMT, in case this generator is used to, e.g., continue a previously interrupted recording (in which case the numbers given should be derived from the PAT/PMT versions last used in the existing recording, incremented by 1.

If the given numbers exceed the allowed range of 0..31, the higher bits will automatically be cleared. SetVersions() needs to be called before SetChannel() in order to have an effect from the very start.
