Blue Iris and CodeProject.AI ALPR

[AlwaysSomething]

2nd topic... Memory leaks.

I definitely had memory leaks with Python when using CPAI 2.6.5. I had to create a scheduled job to stop/start CPAI every night.

With 2.9.5 I think I am too but I created the scheduled job again and I'm also rebooting the PC often so not 100% sure.

I usually don't post until I see someone else has the issue since I just assume it's only me. However, since I'm on a roll here... I have also noticed that when stopping the CPAI service, the Processes can continue to run after the service is stopped.

First, thank you for all the work here.

I'm trying to get this working, but many of the blue iris macros are not populated and I cannot figure out why. With my current setup, I do see the CodeProject.AI reported plate number logged in the memo of the alert image, but &JSON and other variables are simply empty.

If I remove "ai_dump":&JSON from the http post, I see this populated...

{"Image":"&ALERT_JPEG", "camera":"Cam1", "ALERT_PATH": "temp_Cam1_1.jpg", "ALERT_CLIP": "@-1", "timestamp":"2025-05-15T03:08:18.643Z" }

BlueIris 5.9.9.52 on Win11 host
CodeProject.AI 2.9.5 (License plate reader 3.3.4, Object Detection YOLOv5 6.2) on Win11 host (same host as BI)

Anything I can try to get the &JSON macro populated for the alert? I appreciate any help.

From the .dat file saved on the event...

Looks like you have an extra comma behind JSON, it should be:

{"ai_dump":&JSON, "Image":"&ALERT_JPEG", "camera":"&CAM", "ALERT_PATH":"&ALERT_PATH", "ALERT_CLIP":"&ALERT_CLIP", "timestamp":"&ALERT_TIME"}

Yea, sorry, that was a copy/paste error for the screenshot. Without the double comma, I get failures. Logging to a file show me that &JSON is empty, which causes a trainwreck for the ALPR tool. Any other ideas?
