Method Detail

getTimestamp

public static long getTimestamp(byte[] buf,
                                int off,
                                int len)

Gets the RTP timestamp from an SR.

Parameters:

buf - the byte buffer that contains the RTCP sender report.

off - the offset in the byte buffer where the RTCP sender report starts.

len - the number of bytes in buffer which constitute the actual data.

Returns:

the RTP timestamp, or -1 in case of an error.

setTimestamp

public static int setTimestamp(byte[] buf,
                               int off,
                               int len,
                               int ts)

Sets the RTP timestamp in an SR.

Parameters:

buf - the byte buffer that contains the RTCP sender report.

off - the offset in the byte buffer where the RTCP sender report starts.

len - the number of bytes in buffer which constitute the actual data.

ts - the new timestamp to be set.

Returns:

the number of bytes written.

isValid

public static boolean isValid(byte[] buf,
                              int off,
                              int len)

Parameters:

buf - the byte buffer that contains the RTCP sender info.

off - the offset in the byte buffer where the RTCP sender info starts.

len - the number of bytes in buffer which constitute the actual data.

Returns:

true if the RTCP sender info is valid, false otherwise.

setTimestamp

public static int setTimestamp(org.jitsi.utils.ByteArrayBuffer baf,
                               int ts)

Sets the RTP timestamp in an SR.

Parameters:

baf - the ByteArrayBuffer that holds the SR.

ts - the new timestamp to be set.

Returns:

the number of bytes written.

getTimestamp

public static long getTimestamp(org.jitsi.utils.ByteArrayBuffer baf)

Gets the RTP timestamp from an SR.

Parameters:

baf - the ByteArrayBuffer that holds the SR.

Returns:

the RTP timestamp, or -1 in case of an error.

setOctetCount

public static int setOctetCount(org.jitsi.utils.ByteArrayBuffer baf,
                                int octetCount)

Sets the octet count in the SR that is specified in the arguments.

Parameters:

baf - the ByteArrayBuffer that holds the SR.

octetCount - the octet count ot set.

Returns:

the number of bytes that were written, otherwise -1.

setPacketCount

public static int setPacketCount(org.jitsi.utils.ByteArrayBuffer baf,
                                 int packetCount)

Sets the packet count in the SR that is specified in the arguments.

Parameters:

packetCount - the packet count to set.

baf - the ByteArrayBuffer that holds the SR.

Returns:

the number of bytes that were written, otherwise -1.
