I can't build AR 1.5-4 on Ubuntu 14.04 amd64.

make return this :

Yes, I can see the same bug here.

It cannot find GstDevice functions. Those functions were added to Gstreamer in version v1.4. I will investigate this issue (after I have a proper 14.04 running i VM).

The program could fall back to src/pulseaudio.[ch] modules when GstDevice is not available. I removed these and and libpulse-dev from the project when I started to use GstDevice in a.r 1.5-x.

GstDevice and GstDeviceMonitor came first in Gstreamer 1.4.
Ubuntu 14.04 has Gstreamer 1.2 and it does not has support for GstDevice and GstDeviceMonitor modules.

This is my advice .
0) Retrieve the old src/pulseaudio.[ch] module from audio-recorder 1.4.

1) Check in the code if GST_TYPE_DEVICE_MONITOR (or GST_DEVICE) macro has been defined. Something like this.

// Gstreamer 1.4
#include "gstdevice.h"

// Gstreamer 1.2
#include "pulseaudio.h"


2) gstdevice.c and pulseaudio.c modules must have similar call-interfaces (similar functions). This needs to be done.

My intension was to write (but it does not matter really)




Check the version of Gstreamer:
$ gst-launch-1.0 --version

gst-launch-1.0 version 1.4.3
GStreamer 1.4.3

Changed in audio-recorder:
status: New → Won't Fix
