Constructor Detail

MediaStreamTrackDesc

public MediaStreamTrackDesc(MediaStreamTrackReceiver mediaStreamTrackReceiver,
                            RTPEncodingDesc[] rtpEncodings)

Ctor.

Parameters:

mediaStreamTrackReceiver - The MediaStreamTrackReceiver that receives this instance.

rtpEncodings - The RTPEncodingDescs that this instance possesses.

MediaStreamTrackDesc

public MediaStreamTrackDesc(MediaStreamTrackReceiver mediaStreamTrackReceiver,
                            RTPEncodingDesc[] rtpEncodings,
                            String owner)

Ctor.

Parameters:

mediaStreamTrackReceiver - The MediaStreamTrackReceiver that receives this instance.

rtpEncodings - The RTPEncodingDescs that this instance possesses.

Method Detail

getOwner

public String getOwner()

Returns:

the identifier of the owner of this track.

getMediaType

public org.jitsi.utils.MediaType getMediaType()

Returns:

the MediaType of this MediaStreamTrackDesc.

getRTPEncodings

public RTPEncodingDesc[] getRTPEncodings()

Returns an array of all the RTPEncodingDescs for this instance, in subjective quality ascending order.

Returns:

an array of all the RTPEncodingDescs for this instance, in subjective quality ascending order.

getMediaStreamTrackReceiver

public MediaStreamTrackReceiver getMediaStreamTrackReceiver()

Gets the MediaStreamTrackReceiver that receives this instance.

Returns:

The MediaStreamTrackReceiver that receives this instance.

getBps

public long getBps(int idx)

Gets the last "stable" bitrate (in bps) of the encoding of the specified index. The "stable" bitrate is measured on every new frame and with a 5000ms window.

Returns:

the last "stable" bitrate (bps) of the encoding at the specified index.

toString

public String toString()

Overrides:

toString in class Object

matches

public boolean matches(long ssrc)

FIXME: this should probably check whether the specified SSRC is part of this track (i.e. check all encodings and include secondary SSRCs).

Parameters:

ssrc - the SSRC to match.

Returns:

true if the specified ssrc is the primary SSRC for this track.
