oggenc raw recording: Stream error: Invalid argument

[Tong Sun]

Hi,

Seem to me it is impossible to record raw audio of 16 bit signed little endian, 2 channel 44100kHz with oggenc, under precise at least.

According to
http://unix.stackexchange.com/questions/45837/pipe-the-output-of-parec-to-sox
http://thisisabore.net/tag/CLI

it should be as simple as

oggenc --raw -o test.ogg -

However, that always gives me the following error:

Encoding standard input to
         "test.ogg"
at quality 3.00
Stream error: Invalid argument

Done encoding file "test.ogg"

        File length: 0m 00.0s
        Elapsed time: 0m 00.0s
        Rate: 0.0000
        Average bitrate: inf kb/s

It's been working before according to the listed sources, could it be a bug of oggenc in precise?

can you try it with your release please?

BTW, to get the correct MONITOR device, use this

MONITOR=$(pactl list | egrep -A2 '^(\*\*\* )?Source #' | \
Name: .*\.monitor$' | awk '{print $NF}' | tail -n1)

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
