Thank you for your responses, Mr. Achstetter.
Sorry about the delay in my response.

"gst-inspect-1.0" is a very useful utility. Thank you for
introducing it to me.  I was hoping to use Jack, but "jackaudiosrc
does not show up in my "gst-inspect-1.0" output.  Among other things,
I found:

alsa:  alsasrc: Audio source (ALSA)
pulseaudio:  pulsesink: PulseAudio Audio Sink

when using either of these, I get the message:

WARNING: erroneous pipeline: could not link opusenc0 to queue1

I will continue to work with gst-launch-1.0, though
it seems that there is a bit of a learning curve.

To others who may be reading this thread:  how are people
recording the audio to their video at live events?  Keep in mind
that I am recording chamber music, not rock or electronic music.
I am thinking that my best bet may be to use my Nikon camera for
the video, and at the same time use qtractor for the audio, and
then sync up the two in a video editor.

My Nikon camera takes excellent video, probably better than
my webcam anyways.
