Dear all,
I am trying to open two differernt audio lines simultaneously.
Unfortunately the runtime throws this exception:
javax.sound.sampled.LineUnavailableException: Another capture device is
already open
at com.sun.media.sound.SimpleInputDevice.nOpen(Native Method)
at
com.sun.media.sound.SimpleInputDevice.implOpen(SimpleInputDevice.java:275)
at com.sun.media.sound.AbstractMixer.open(AbstractMixer.java:286)
at com.sun.media.sound.AbstractMixer.open(AbstractMixer.java:334)
at com.sun.media.sound.AbstractDataLine.open(AbstractDataLine.java:103)
at
com.sun.media.sound.SimpleInputDevice$InputDeviceDataLine.open(SimpleInputDevice.java:632)
at com.sun.media.sound.AbstractDataLine.open(AbstractDataLine.java:139)
at com.fasttvr.audio.CaptureTool$CaptureThread.run(CaptureTool.java:240)
Both audio lines I have tried can be opened successfully when the other
one has been closed before. It is even possible to open a single line
more that one time. But it is not possible to open the two lines
simultaneously. Why not? Same code is running under XP/Linux without any
problem!
I have been trying the OS X 10.5 default (build 1.5.0_13-b05-237) and
the 1.6 developer preview (build 1.6.0_04-b12-45-optimized) both are faulty.
I highly appreciate any comment on this.
regards
spachner
