I don't think this is a bug of vorbis-tools, but either a bug of parec (or some underlying library) or a user error.
Both the content of the error message and the moment in which it appears suggest that the message actually comes from parec instead of oggenc. I grepped the source code of oggenc and neither the string "Invalid argument" nor "Stream error" appear anywhere. However, a web search revealed that parec does produce that message on occasion [1] [2] [3]. However, I'm not sure, if it is parec directly. Some results suggest that the message comes from pulseaudio. Have you tried piping to something different than oggenc? Or reading from a different device? Piping from parec to oggenc works flawlessly on my Ubuntu 14.04 system for reading from both a real input device and a monitor: parec -d alsa_output.usb-Sennheiser_Sennheiser_USB_Headset_0000000000-00-Headset.analog-stereo.monitor | oggenc --raw -q 8 -o test.ogg - parec -d alsa_input.usb-Sennheiser_Sennheiser_USB_Headset_0000000000-00-Headset.analog-stereo | oggenc --raw -q 8 -o test.ogg - Cheers, Martin [1] http://lists.freedesktop.org/archives/pulseaudio-discuss/2010-February/006585.html [2] https://groups.google.com/forum/#!msg/sdr-widget/RPn147OX9ak/BxlrTuNLQj4J [3] https://github.com/mumble-voip/mumble/issues/1297 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1099873 Title: oggenc raw recording: Stream error: Invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vorbis-tools/+bug/1099873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
