cTsPayload::cTsPayload ( uchar Data,
int  Length,

)

Creates a new TS payload handler and calls Setup() with the given Data.

bool cTsPayload::AtPayloadStart ( void  )
inline

Returns true if this payload handler is currently pointing to the first byte of a TS packet that starts a new payload.

bool cTsPayload::AtTsStart ( void  )
inline

Returns true if this payload handler is currently pointing to first byte of a TS packet.

int cTsPayload::Available ( void  )
inline

Returns the number of raw bytes (including any TS headers) still available in the TS payload handler.

bool cTsPayload::Eof ( void  ) const
inline

Returns true if all available bytes of the TS payload have been processed.

bool cTsPayload::Find ( uint32_t  Code)

Searches for the four byte sequence given in Code and returns true if it was found within the payload data.

The next call to GetByte() will return the value immediately following the Code. If the code was not found, the read index will remain the same as before this call, so that several calls to Find() can be performed starting at the same index.. The special code 0xFFFFFFFF can not be searched, because this value is used to initialize the scanner.

uchar cTsPayload::GetByte ( void  )
int cTsPayload::GetLastIndex ( void  )

Returns the index into the TS data of the payload byte that has most recently been read.

If no byte has been read yet, -1 will be returned.

void cTsPayload::SetByte ( uchar  Byte,
int  Index 
)

Sets the TS data byte at the given Index to the value Byte.

Index should be one that has been retrieved by a previous call to GetIndex(), otherwise the behaviour is undefined. The current read index will not be altered by a call to this function.

void cTsPayload::Setup ( uchar Data,
int  Length,
int  Pid = -1 
)

Sets up this TS payload handler with the given Data, which points to a sequence of Length bytes of complete TS packets.

Any incomplete TS packet at the end will be ignored. If Pid is given, only TS packets with data for that PID will be processed. Otherwise the PID of the first TS packet defines which payload will be delivered. Any intermediate TS packets with different PIDs will be skipped.

bool cTsPayload::SkipBytes ( int  Bytes)

Skips the given number of bytes in the payload and returns true if there is still data left to read.

bool cTsPayload::SkipPesHeader ( void  )

Skips all bytes belonging to the PES header of the payload.

int cTsPayload::Used ( void  )
inline

Returns the number of raw bytes that have already been used (e.g.

by calling GetByte()). Any TS packet of which at least a single byte has been delivered is counted with its full size.
