I just built the latest on the 1.14 branch. (I can see your commits in the
What is happening now is that the video in the lower-right corner plays
smoothly until just before the first slide transition. When I say "slide
transition" I mean the point in time when the background image gets changed.
At the point of the first slide transition, the foreground video freezes on
a single frame. It stays frozen until the next slide transition, at which
time it switches to a new frame, but the video is remains frozen. The
video never un-freezes. On each slide transition, it simply displays a new
frame but there is never any motion to the video ... it is always frozen on
a single frame.
