[Beta testers wanted] MediaCheck — read-only Windows media health and duplicate checker

[guy_incognito19 0]

I am looking for a few Windows users to test MediaCheck 0.15 Beta. It checks the media files themselves rather than connecting to an Emby database, so it can be used with an existing Emby library without changing Emby or the media files.

Current features include quick FFprobe checks, optional full video decoding, plain-language issue explanations, multiple library locations, cached refreshes, focused rechecks, scan history, and read-only duplicate comparison. It never renames, moves, repairs, or deletes media.

The package contains the installer, a 25–40 minute testing checklist, feedback form, privacy/support explanation, SmartScreen instructions, and checksums. I am particularly looking for feedback from users with large collections, multiple drives, NAS folders, or known problem files.

Download and details:
https://github.com/stewlowe/MediaCheck/releases/tag/v0.15.0-beta

Please reply in this thread with feedback. If a problem needs more detail, MediaCheck can export a privacy-conscious support bundle from its Diagnostics window.

The beta is free. The installer is not yet code-signed, and the application may eventually have a paid edition; both points are disclosed before download.

Development disclosure: the project was built with substantial AI coding assistance under my direction and has 73 automated tests plus hands-on Windows testing.

Update: MediaCheck 0.15.2 Beta is now available. It adds clear in-app instructions for submitting feedback and optional diagnostic information. Nothing is uploaded automatically.

Download and details:
https://github.com/stewlowe/MediaCheck/releases/tag/v0.15.2-beta

Please use this version for testing rather than the original 0.15.0 release linked above.

Update: MediaCheck 0.16.0 Beta is now available.

It adds Check new files, a temporary preflight workspace for checking downloads, copies, recordings, or encodes before adding them to an Emby library. The quick check examines file structure and stream metadata; the optional full decode reads the entire primary video stream. These temporary results are not added to the permanent library cache or scan history.

This build also improves the preflight window on shorter or display-scaled Windows desktops.

Download and release notes:
https://github.com/stewlowe/MediaCheck/releases/tag/v0.16.0-beta

MediaCheck remains read-only and does not connect to or change the Emby database or media files. Feedback is welcome in this thread.

No source code, only compiled binary. 
If you really want feedback on the program you should disclose the source, otherwise this just looks like an attempt to spread malware. 
Especially from someone who doesn't disclose his real name, has zero reputation and even wants to make business that way (hello tax authorities). 
In my humble opinion this thread shouldn't even exist in this forum.

I understand the hesitation about running an unsigned application from a new developer. The repository currently contains documentation and releases; the application source isn’t published, and that is disclosed.

The beta is optional, and I respect anyone choosing not to install it. I’ve disclosed the unsigned installer, AI coding assistance, and the possibility of a future paid edition. Checksums are provided to verify the download, although they don’t establish that software is safe.

I’m here to gather feedback and improve the utility. If the moderators consider the thread unsuitable for this section, I’ll respect their decision.
