Doesn't work with Alsa or Jack about sampledrawer HOT 5 CLOSED

I have added a new audio driver, using GStreamer instead of Qt multimedia capabilities. This should allow using ALSA, PulseAudio and Jack properly and any other audio sink supported by GStreamer.

To use ALSA:
./sampledrawer --audio-driver=gstreamer --audio-device='alsasink'

PuleAudio:
./sampledrawer --audio-driver=gstreamer --audio-device='pulsesink'

Jack:
./sampledrawer --audio-driver=gstreamer --audio-device='jackaudiosink'

Jack without automatic port connections:
./sampledrawer --audio-driver=gstreamer --audio-device='jackaudiosink connect=0'

Add an effect ('freeverb' Reverberation/room effect in this case) before sending audio to alsa:
./sampledrawer --audio-driver=gstreamer --audio-device='freeverb ! alsasink'

For this to work GStreamer with appropriate sink and affects plugin must be installed, as well as python gobject-introspection binding and GStreamer gobject-introspection data ('python3-gi' and 'gir1.2-gstreamer-1.0' packages in Ubuntu).

Doesn't it? I have used the basic Qt media player and decoder, assuming it should 'just work' everywhere. I have not tested it with anything else than PulseAudio, though.

How exactly does it not work for you? Any error message?
Do you have audio in other Qt5 based applications?

I have added '--auto-device' command-line option. A quick hack, but maybe it helps.

By default it outputs:

PulseAudioService: pa_context_connect() failed
using null output device, none available

With ./sampledrawer --audio-device default it does work with my default alsa device \o/

thnx!

Got some more feature requests, but nice project. Was looking for something like this.

Nice, will have a try soon!
