Video scrubber controls hang jAlbum
Posted:

Mac OS 11.6, jAlbum 21 through to current version, ffmpeg versions (current jAlbum version) N-99463-g3a035a8cd2-tessus and ffmpeg version (latest ffmpeg version) N-104775-g228b25ad9b-tessus.
Moving any of the scrubber controls, or clicking on a new location on the bars, causes jAlbum to hang. There is no report in the config folder and no printout to the system console. I can sometimes move the thumbnail selector without a hang, but it is rare. The start/stop points always cause a hang.
It would appear to be the OS, Java or my machine. Can other Mac users confirm if they get the same result or not?

No problem on macOS 11.6.1, jAlbum 25.1.1, ffmpeg N-99463-g3a035a8cd2-tessus.
I'm very proud of myself for having figured out how to check the ffmpeg version on a Mac, at this hour of the morning, without even finishing the first cup of coffee. I should quit while I'm ahead, and go back to bed.

Good new for jAlbum, bad news for me. Thanks.

I just drag ffmpeg to a terminal window and hit enter

That's what I did. But to a Windows person, a "terminal window" is where you buy train tickets.
ETA: macOS is still peppered with these kinds of weird anachronisms. "Terminal window" goes back to the days of using a terminal connected to a mainframe somewhere. I also enjoy "ejecting" a DMG, as if there were a floppy disk involved.

A DMG is. Disc Mounting Image, so having opened the ‘disc’ ejecting it is appropriate.

I have a new bit to this puzzle. Created a brand new config folder and opened a video (double clicked it) then set it to play. at a point during playback clicked the camera icon to make a thumbnail. Fine it created the thumbnail, did not hang but gives this info in the system console Dec 07, 2021 3:16:25 PM net.javainthebox.caraibe.svg.SVGContentBuilder eventLoop
INFO: Non Support Element: <title>

Just set logging to All, entered edit mode for the video and then opened system console and cleared its contents. Clicked and drag the start video point and it hangs, with nothing printed to the console. Weird.

I have run a thread dump script new Thread(() -> {
window.statusBar.setText("Prepare to change video start point...");
Thread.sleep(5000);
window.statusBar.setText("Do it now!");
Thread.sleep(5000);
window.statusBar.setText("Dumping threads");
JAlbum.dumpThreads();
Thread.sleep(5000);
JAlbum.dumpThreads();
}).start();
Results attached.
The really strange thing is with the script running jAlbum doesn't hang. I'm at a complete loss as to what to try next, a new Mac sounds good!

I get the same error on my Macbook, and with no hanging afterwards - the sliders still behave themselves.
In Windows, I get a different, more serious error when doing that. I need to get back on there and grab that one - I'll post back in a few minutes.
ETA: Got the more serious error only once in Windows, and I can't reproduce it. I do get the same seemingly harmless console error lines, however.

Seems to be a very rare error, one that I can avoid.
