April 2020 • Macworld 23standard-definition AVI movie began streaming
in under 20 seconds, while a 4K MKV of similar
length required several minutes of preparation
before playback commenced, including extra time
to process embedded subtitles, which can be
bypassed when not needed.
To be fair, JustStream has a maximum output
resolution of 1080p HD, so anything higher is
redundant anyway. Finally, while the app is free to
download, you’ll be interrupted every 40 minutes
unless you decide to purchase a licence code.
Verdict
Mirroring offers few advantages over built-in
AirPlay, but JustStream redeems itself when it
comes to streaming video files to any screen in
the house. J.R. Bookwalter
