[LOGGED] Warning about pjlink

zedociel

It took me a while, but i finally nailed it.

With two panasonic PT-MZ880, a windows 10

(Édition Windows 10 Famille
Version 20H2
Installé le ‎24.‎09.‎2021
Build du système d’exploitation 19042.1526
Expérience Windows Feature Experience Pack 120.2212.4170.0)

and the latest version of isadora, the pjlink actor make isadora crashes.

Some colleagues in Geneva also had trouble with it.

I don't know who change what (panasonic, microsoft, etc..) , but as it took me a while to get it and i lost quite some time on it, i thought a warning here could be useful to someone.

As i have a premiere today, i don't really have time to dig it more, but i'm 98% about what caused my isadora file to crash constantly.animalvidy7.izz

When I work with your file I get the pinwheel of death after trying to go from Scene 2 to Scene 3 and I have to force quit. Is the behavior you are experiencing too, or are you seeing something different?

Best wishes,

I don't have the pinwheel of death. Isadora simply quit. When i delete the enter scene trigger on the pjlink actor, everything just goes smoothly.

Try putting a Trigger Delay actor set to 0.05 seconds between the Enter Scene Trigger and the Send PJLink actors. Maybe this has to do with the speed with which you're asking the Send PJLink to execute commands immediately after it has become active in a Scene.

If that doesn't work and you're trying to send commands to two devices (I seem to remember you are), maybe put a delay between sending a command to the first one and sending a command to the second one so that Isadora has time to send the first command (instead of trying to send it at the exact same time as the second command).

Best wishes,

Thanks Woland,

I'm effectively triggering two projector at the same time. I tried the different delays in all senses but didn't get a stable enough result.

It's really weird because it's something i used a lot before and never had trouble with it before.

Right now, i'm on another show and they had the exact same problem. Isadora quitting every time they activate the pjlink. They ended outsourcing the shutters.

We both used the pjlink actor a lot before and hadn't that kind of troubles before.

Something changed. I don't know if it is in the panasonic firmware, or windows updates but it's really weird.

I don't have any issue stepping through our file (latest build of Windows 10).
However, I have no media connected, and no projectors at the moment.
I will plan to run some pjlink tests with my Panasonic projectors when I have a free period.

When Isadora quits, are you presented a crash reporting dialog?
If so, DM me your email entered to submit these reports, so I can look into the report data.

If something changed recently, it couldn't have been on our end, since the last time we released an update to the Send PJLink plugin was October of 2021.

I know. I had a show in december with the latest izzy version and shutter control and hadn't any issue with it (same computer, older panasonic projectors). That's why it took me so long to find out what was wrong.

Did you get any resolution to this issue? I tried to implement video mute and AV mute (both on and off) commands last night with two Epson ProL1405 projectors and have the same issue. I tried delaying the command to one projector so that the responses wouldn't overlap to no avail. (To be clear, the commands "work" the projectors will mute (or unmute) but then Isadora crashes to desktop.)

I'm happy to share my file if it's of any use...

I can confirm that I've experienced similar behavior in during the past several months. I first encountered it while using Isadora on Windows 10 computers, but then found it would also occur on some but not all Mac OS computers (using similar OS versions). It would only happen when I would jump to a new scene and had an enter scene trigger into the PJ link actor. I went about a couple different methods of resolving this including creating a second instance of Isadora that would sit in one scene and just send shutter commands when necessary, and also similar to what @Woland suggested--introducing a very short delay between the enter scene trigger and the PJ Link actor.

I'd submitted crash logs and created a topic and found a couple other folks on the forum having trouble with this, so I thought I'd chime in here to add a plus one and hope this can be addressed. It's been okay with the work-arounds, but it had been working very well previously, so I'd love to help find a solution for this.
