gst-launch-1.0 preview is just a black video - no error messages

[andanders]

I am unable to use my camera inside the docker container. Testing with gst-launch-1.0 v4l2src ! videoconvert ! autovideosinki get a preview window with just a black screen. The same command runs just fine outside the container. So I know the camera works with v4l2src.

To start the container I run

$ docker/run.sh

Addendum

My actual purpose with this issue is to fix roslaunch ros_deep_learning video_viewer.ros1.launch, but I figured it might be related, and gst-launch-1.0 is easier to test with.
