Don't compare booleans for equality to TRUE and FALSE
...
TRUE is 1, but every other non-zero value is also considered true. Comparing
for equality with TRUE would only consider 1 but not the others.

video-frame: Mapping a frame with inconsistent values between GstVideoMeta and GstVideoInfo is a bug

It will cause the frame to be initialized with inconsistent values that then
later can cause crashes or any other kind of interesting and hard to debug
bugs.
