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.

void cTsPayload::SetByte | ( | uchar | Byte, |

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 | 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.
