No, it means that filesrc is not providing the size of buffer that
compositor/glvideomixer/'any other video element' wants.  Which is what
videoparse is fixing up for you.  The convention with GStreamer is one buffer
== one video frame which may have not been true by the buffers output by
filesrc.  Marking as invalid for this reason.
