Scanner failing to run

Hi,

Scanner is failing to run for some reason - running it from cmd gives the following:

pkg/prelude/bootstrap.js:1872
throw error;

This is on all versions (I have tried 2.4.3, 2.5.0 and the latest build of 2.6.0). It appears to have been starting fairly recently - possibly with a windows update?

I am also seeing some weirdness with the BMD card in this system - I can loop a video for a decent while, but after a few hours the embedded audio stops. The only way to fix this is to quit the server and restart it. The card is a Decklink Duo, with Desktop Video 16.1 running. Machine is Windows 11 25H2. There is nothing noted in the logs when the audio disappears.

Anyone else seen anything like this?

I think the scanner config parser is a bit particular about line endings or spacing or something like that.

For the audio disappearing, I think I had this happen earlier today while debugging another issue. I think windows 11 has gotten a lot more aggressive with limiting timers of ‘non foreground’ processes, which casparcg appears to it as most of the time. I suggest try adding a screen consumer and keeping that in focus/visible. If that resolves it then I have a fix in the works that will likely resolve this properly.

Thanks for the hint on the config parser - I’d commented something out, which was causing this.

Regarding the audio - even with a screen consumer visible & focused, still seeing the audio stop after a number of hours (not consistent - can be anywhere between 4 and 10). I do suspect it is a Windows thing, as we started seeing it earlier this year.

Regards,

Mark
