Constructor Detail

MixerTrack

public MixerTrack(NativeObject.Initializer init)

For internal gstreamer-java use only

Parameters:

init - initialization data

Method Detail

getChannelCount

public int getChannelCount()

Gets the number of channels in this track

Returns:

the number of channels

hasFlag

public final boolean hasFlag(int flag)

Checks if a flag is set on this track.

Returns:

true if the flag is set

isInput

public boolean isInput()

Checks if this track is an input track.

Returns:

true if this track is an input track

isOutput

public boolean isOutput()

Checks if this track is an output track.

Returns:

true if this track is an output track

isMuted

public boolean isMuted()

Checks if this track is currently muted.

Returns:

true if this track is muted

isRecording

public boolean isRecording()

Checks if this track is currently recording.

Returns:

true if this track is recording

setVolume

public void setVolume(int[] volumes)

Sets the volume on each channel in a track.

Short note about naming: a track is defined as one separate stream owned by the mixer/element, such as 'Line-in' or 'Microphone'. A channel is said to be a mono-stream inside this track. A stereo track thus contains two channels.

Parameters:

volumes - an array of integers (of size track.getChannelCount()) that gives the wanted volume for each channel in this track.

getVolume

public int[] getVolume()

Gets the current volume(s) on the given track.

Returns:

an array of int values containing the current volume for each channel

setMuted

public void setMuted(boolean mute)

Mutes or unmutes the given channel.

Parameters:

mute - true to mute, false to unmute the track

setRecording

public void setRecording(boolean record)

Enables or disables recording on the given track. Note that this is only possible on input tracks,

Parameters:

record - true to record, false to stop recording
