Based on is just released on Chrome 57 stable "Behind a flag". Where can I find it in  chrome://flags? It seems not having it.
#11: either "the flag" that enables all interesting stuff:

or the individual 

#12: then status is wrong. None of tests works even on Chrome Canary 59.0.3038.0 chrome://flags/#enable-experimental-web-platform-features enables.

#13: I just tried some on Mac 59.0.3037.0 and most of
them work; plz make sure that you access via https:// 
Also, the code is wired on Mac and Android only ATM, plus:
- Mac QR detection doesn't detect slanted QR codes, not
- Mac Text detection detects "bubbles" of text, but 
 doesn't decode the text inside.
@mcasas, tested over HTTPS on Win10 64-bit build, all test-cases fails with warnings like "Boo, Text Detection failed: NotSupportedError: Text Detection not implemented.",
#15: only the Mac and Android implementations are wired 
so far. Win10 will be coming soon.
#16: @mcasas, I suggest you update the status in, currently shown "Chrome for desktop release 57" what's understood as supported on Windows desktop.

This is great. Just tried the API and it works like charm.
Labels: migrated-launch-owp Type-Task
This issue has been automatically relabelled type=task because type=launch-owp issues are now officially deprecated. The deprecation is because they were creating confusion about how to get launch approvals, which should be instead done via type=launch issues.

We recommend this issue be used for implementation tracking (for public visibility), but if you already have an issue for that, you may mark this as duplicate.
