Just wanted to chime in. I needed to convert some music today and your
tool worked almost perfectly for me. :+1:

Regarding this issue: I'm using `soundconverter`
3.0.0~alpha1+git20151209-1 with GStreamer 1.0 from Debian Multimedia and
tried to convert some 320 MP3s into Opus. However I got an error message
when I tried to do so:

    GStreamer error when creating pipeline
    gst_parse_error: no property "cbr" in element "opusenc3" (2)

After finding this issue, I did a short investigation and it turns out
that the `cbr` option does not exist in GStreamer 1.0; instead the
`bitrate-type` option was introduced:

    bitrate-type        : Bitrate type
                         flags: readable, writable, changeable in NULL, READY, 
PAUSED or PLAYING state
                          Enum "GstOpusEncBitrateType" Default: 0, "cbr"
                             (0): cbr              - CBR
                             (1): vbr              - VBR
                             (2): constrained-vbr  - Constrained VBR

Replacing `cbr=false` with `bitrate-type=vbr` resulted in a proper VBR
Opus being generated:
