Crash opening webcam scan on MacOS Intel

[Thats77]

creating a new wallet in sparrow 1.8.1 on a mac intel and selecting scan airgapped keeps crashing sparrow. all wallets selected to scan are crashing the sparrow wallet

[craigraw]

Please take a look for a crash dump file. It will be named hs_err_pid<pid>.log (the <pid> will be some number) and will either be in the root folder (/) of your Mac, or in a temporary folder under /var/folders/ (for example, /var/folders/7y/cvqm9r6n0cgddhm921cm1zwc0000gn/T/). You can use Go > Go To Folder in Finder to see these locations.

If you find it, please attach it here. Alternatively you can email it to craig at sparrowwallet.com

[craigraw]

Please try the following:

1. Close Sparrow
2. In Finder, click Go > Go To Folder... and enter ~/.sparrow in the textbox
3. Look for the config file when the folder opens and open it in a text editor like TextEdit
4. Look for the value "hdCapture" and set it from true to false. So

  "hdCapture": false,

Save the file, close it, open Sparrow and try scanning again.

Thanks for the quick feedback. Your two recent posts are contradictory though - was it false and you set it to true, or the other way around?

[Thats77]

I did exactly the opposite of what you suggested.

[Thats77]

"hdCapture": true, - this is working

false wasn't working

[craigraw]

It appears that your system does not support the lower 640x480 scanning resolution for some reason.

Notes for further debugging:

This issue appears to exist only on some Macbook Pro 14" Intel systems. Both reported incidents were running macOS Ventura.

I appreciate everything. Onward and upward ✌️

Hi guys,

i have a similar issue, although the logs may be different. I am running Sparrow 1.8.1 under Win 10 Pro x64 22H2 on IMac Intel(R) Core(TM) i7-10700K CPU @ 3.80GHz 3.70 GHz (Bootcamp native install). I am using the buit-in FaceTime HD-Camera that works in all other apps i have (Kamera, Zoom, Browser ...)

After opening the scan-option under Airgapped Hardware Wallet, Sparrow behaves unresponsive in both modes using HD or non HD option, whil only in HD option i get a black preview in the window.

Log says:

2024-01-12 10:00:15,017 ERROR [atomic-processor-1] c.s.s.c.WebcamScanDevice [null:-1] Timeout when requesting image!
2024-01-12 10:00:20,589 ERROR [frames-refresher-[0]] c.s.s.c.WebcamScanDevice [null:-1] Timeout when requesting image!

Don't find any config file in C:\Users\User\AppData\Local\Sparrow\runtime

any suggestions how i could proceed? Thanks!

@schmonet This is a different problem. Please open a separate Github issue.

I had the same issue as the OP, except with v1.9.1, and setting hdCapture to false fixed it.
