I believe the GstVideoEncoder base class now tries to estimate its own latency.

However, I can still reproduce the issue with:

  gst-launch-1.0 -v v4l2src ! 'video/x-raw,width=640,height=480,framerate=30/1'
! queue ! theoraenc ! theoradec ! queue max-size-buffers=3 ! xvimagesink

The question is: is it actually a bug?

Arguably theoraenc is simply not fit for low latency use cases, at least not in
our default configuration. (I have a vague memory of it taking very very long
to encode some frames when there's rapid motion involved).
