[gst-devel] simultaneous OSS playback/record

[Wilson, Diego]

Edgard,

None of them work. I'm getting the following error on all of them:

ERROR: from element /pipeline0/osssrc0: Unable to open device /dev/dsp
for recording: Device or resource busy

Again, each individually works fine.

Regards,

The three below seems to work for me, what of them doesn't work for you?

1-

gst-launch-0.10 osssrc ! osssink

2-

gst-launch-0.10 osssrc ! fakesink audiotestsrc ! osssink

3-

gst-launch-0.10 osssrc ! fakesink
gst-launch-0.10 audiotestsrc ! osssink

BR,
Edgard
