Method Detail

findSyncBytePosition

public static int findSyncBytePosition(byte[] data,
                                       int startPosition,
                                       int limitPosition)

Returns the position of the first TS_SYNC_BYTE within the range [startPosition, limitPosition) from the provided data array, or returns limitPosition if sync byte could not be found.

readPcrFromPacket

public static long readPcrFromPacket(ParsableByteArray packetBuffer,
                                     int startOfPacket,
                                     int pcrPid)

Returns the PCR value read from a given TS packet.

Parameters:

packetBuffer - The buffer that holds the packet.

startOfPacket - The starting position of the packet in the buffer.

pcrPid - The PID for valid packets that contain PCR values.

Returns:

The PCR value read from the packet, if its PID is equal to pcrPid and it contains a valid PCR value. Returns C.TIME_UNSET otherwise.
