[Request] Add support for HTTP Basic Auth credentials to Classic Webcam snapshot camera

[mikeb9x]

The problem

OctoPrint can't access snapshot URL from IP camera. Test shows "Snapshot test failed / Could not retrieve snapshot URL, please double check the URL". Stream works well.

Config:
Stream URL: http://user:password@X.X.X.X/mjpg/video.mjpg [accessible through browser]
Snapshot URL: http://user:password@X.X.X.X/jpg/1/image.jpg [accessible through browser]

'Validate SSL' option makes no difference.

Did the issue persist even in safe mode?

Yes, it did persist

If you could not test in safe mode, please state why ("currently printing" is NOT an excuse!)

You haven't provided a system info bundle, which includes logs which are really crucial here. But based on the URLs you shared, I'm going to assume the problem here is that your username@password syntax simply is deprecated and not supported by the underlying Python library used for fetching the snapshot. Tbh, I'm kinda surprised the Stream URL works in your browser in 2024.

See also the corresponding section in RFC3986.

However, that means that we need some way to provide Basic Authentication credentials for the snapshot URL, so this just turned into a Feature Request.

I can't provide logs because my SD card died and I'm waiting for a new one (32GB). For some reason I can't use my 64/128GB cards because I'm having partitioning issue at the first boot.
Stream in OctoPrint was working well despite having the same basic authentication. Problem was only with the snapshots.
In Firefox I need to confirm login (You are about to log in to the site “X.X.X.X” with the username “user”.), Chrome just starts the stream/shows snapshot.

Basic, Digest and Bearer auth will be supported from 1.11.0 onward via new options in the Classic Webcam settings.

Additionally, if you configure a snapshot URL with the deprecated in-URL credentials, OctoPrint will warn you about that and refer you to the advanced options containing the authentication settings.
