Note that audio/video synchronisation will be broken. You system is
probably not fast enough to reach full frame rate, and then combine
with another plausible bug (multiqueue higher limit might be too low
for 4K with slower then real-time decoder).

Another option would be to increase processing-deadline property on
your display sink.
