Chris Cunningham of Google, author of the Media Capabilities specification, has been invited to join the meeting remotely to discuss “Intended capability additions to the Media Capability API around codec switching and smooth transitions”. I am waiting for confirmation from him as to day and time.

W3C Privacy Interest Group have an interest in reducing API surface to reduce fingerprinting. How does this affect Media Capabilities as well as our general architecture of a web-based platform with capability discovery at its core?

DPC Version 2 - what is in and what is out?

Pick and discuss HATF https://github.com/w3c/webmediaapi/issues/199

On Media Source Extensions, we do not limit this to the ISO BMFF byte stream format. Is this intentional? Or said differently, should it not mandate the support of ISO BMFF byte stream format On Web Audio API: o Has anyone checked how the Web Audio API interacts with our audio profiles? o Does W3C has tests for the Web Audio API that may be combined reused for DPCTF tests?

Upgrading the AWS instance that https://webapitests2018.ctawave.org/ runs on to reduce timeouts

HATF https://github.com/w3c/webmediaapi/issues/211

During our initial discussion on this topic, I believe we left this as we should either add some technical details around handling a Cue or explicitly agree to not include any details.

HATF w3c/webmediaapi#219

Discuss standing up https://webapitests2019.ctawave.org/ server to prepare for the updated test set. Initially can be stood up with the 2018 tests as placeholder.

Title: Type 1 Playback & W3C Standards TF: DPCTF

When I gave an update on CTA WAVE during the W3C Media & Entertainment Interest Group meeting at TPAC, Type 1 Playback (https://github.com/cta-wave/device-playback-task-force/issues/31) caught the attention of the group. Those present stated if there is anything from a W3C standards perspective that could help with that, they'd be happy to discuss.

This may be more of a "for awareness" type item than an actual issue to address, but either way I feel it is worth mentioning at the F2F.

Review proposals for UI for Test Suite interface

Title: Web Media API Test Suite updates to support Web Platform Tests TF: HATF

There is an open PR on the web-platform-tests RFCs repo to work through how we could upstream the WMAS2018 test suite changes back to the web-platform-tests project. The comments in that PR explain the initial set of asks from the WPT team. I'd like to understand our plan to address those comments and also explore how we can best build the WMAS tests in a way so that they can easily upstream back to WPT what is useful, keep separate what is not useful to WPT, and ease the ability to pull in the latest from WPT as we make future updates.

Title: Shorten lead time between Web Media API Snapshot updates and subsequent Test Suite updates TF: HATF

Ideally, WMAS test suite changes would be made at the same time updates to the WMAS spec are committed to GitHub (before the annual Snapshot is even officially published). In reality the time gap between the two is months. How can we bring those closer together?
