Constructor Detail

RetransmissionRequesterImpl

public RetransmissionRequesterImpl(MediaStream stream)

Method Detail

reverseTransform

public RawPacket reverseTransform(RawPacket pkt)

Reverse-transforms a specific packet. Implements SinglePacketTransformer.reverseTransform(RawPacket).

Overrides:

reverseTransform in class SinglePacketTransformerAdapter

Parameters:

pkt - the transformed packet to be restored.

Returns:

the restored packet.

close

public void close()

Closes this PacketTransformer i.e. releases the resources allocated by it and prepares it for garbage collection. The (default) implementation of SinglePacketTransformer does nothing.

Specified by:

close in interface PacketTransformer

Overrides:

close in class SinglePacketTransformer

getRTPTransformer

public PacketTransformer getRTPTransformer()

Gets the PacketTransformer for RTP packets.

Specified by:

getRTPTransformer in interface TransformEngine

Returns:

the PacketTransformer for RTP packets

getRTCPTransformer

public PacketTransformer getRTCPTransformer()

Gets the PacketTransformer for RTCP packets.

Specified by:

getRTCPTransformer in interface TransformEngine

Returns:

the PacketTransformer for RTCP packets

enable

public void enable(boolean enable)

Enables or disables this RetransmissionRequester.

Specified by:

enable in interface RetransmissionRequester

Parameters:

enable - true to enable, false to disable.

setSenderSsrc

public void setSenderSsrc(long ssrc)

Sets the SSRC to be used by this RetransmissionRequester as "packet sender SSRC" in outgoing NACK packets.

Specified by:

setSenderSsrc in interface RetransmissionRequester

Parameters:

ssrc - the SSRC to use as "packet sender SSRC".
