commit fe1505549280fe1b7e4b7a4c5907a71b66a8c809
Author: guidou <guidou@chromium.org>
Date: Thu Apr 13 17:31:05 2017

Count usage of mediastream audio and video constraints.

This will help ascertain which nonstandard constraints are good
candidates for standardization.

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.

For more details see here: https://docs.google.com/document/d/1JA6RohjtZQc26bTrGoIE_bSXGXUDQz8vc6G0n_sZJ2o/edit

Status: WontFix (was: Assigned)
We will not implement nonstandard constraints with standard syntax.
If necessary, we will request standardization of some of the old goog constraints.
