ges-launch-1.0 command-line

[David Ing]

I am trying to run a ges-launch-1.0 command and it doesn't seem to
recognize the caps that I'm providing with my --format parameter.

I am on an Ubuntu 18.04 system where I have installed several debian
packages.

ges1.0-tools
gstreamer1.0-tools
gstreamer1.0-libav
gstreamer1.0-plugins-good
gstreamer1.0-plugins-bad
gstreamer1.0-plugins-ugly


Using gst-inspect-1.0, I can see that qtmux and voaacenc are installed.  So
there are at least some plugins which are capable of getting the job done.

I have also tried specifying more detailed caps but I get the same error.


Can I get a tip on how to get past this?
