You can also use a third-party utility like https://scanapp.org/ to extract the TOTP authentication key from a QR code.

Yet another package extending zxing. The implementation was a bit easier to follow although this seemed to also use an old version of zxing, so I was a bit cautious about using it.

I've been working on a web application that has a bar code code scanning component and I will say that while the apparent performance of this library is impressive, I am not a fan of this pricing model, and that alone pushes me to use alternative libraries [1]. As an aside, the library I'm thinking has zero issues with scanning any of the examples in your OSS comparison [2] using the demo implementation [3] (it scans bar codes despite the name being "html5-qrcode").

For a library like this, the only really appealing pricing model is a flat fee that buys unlimited use of the version I buy in perpetuity (even if that fee is several thousand dollars). I'm not, however, going to pay monthly forever for code that (1) you wrote once and is now static, (2) that you aren't hosting, and (3) that I need to integrate into my application myself. If I need support I will happily pay you a support fee. Moreover, I cannot take on the liability of my app's bar code scanner ceasing working because you decide to close your doors and then the license won't reactivate.

I recently spent quite a while researching different js barcode scanning libraries for work, so I’ll share my experience. The best free library I found was html5-qrcode. It uses zxing under the hood and it’s pretty adequate for most use cases. For any personal project it’s probably the best you’re gonna get. Like you, we found that it had trouble when barcodes were obscured, and since ours were really long code128 barcodes, it really struggled with those. Unfortunately this meant we had to pivot to one of the paid options. Dynamsoft, Scanbot, and Scandit all seem to do a really good job of picking up barcodes, so for professional use any of those 3 will probably meet your needs. From my experience Scandit seemed the best at picking up tough to read codes, so that’s the option we went with. Hopefully this is enough to get you started!
