Video only playing one frame with JACK

When trying to play back video it only plays one frame and then stops. Is this a known issue? It doesn’t seem to depend on the type of media I’m importing.

Shotcut 20.02.17, Jack audio

Operating System: Kubuntu 19.10 64-bit
KDE Plasma: 5.16.5 KDE Frameworks: 5.62.0
Qt Version: 5.12.4
Kernel Version: 5.3.18-050318-lowlatency
Processors: 8 × Intel® Core™ i7-4702MQ CPU @ 2.20GHz

JACK transport integration broke in this version. I fixed this for the next version 20.04.

Ah, great. Thanks Dan!
