   - w3c/media-wg#13 TPAC F2F 2020
   <https://github.com/w3c/media-wg/issues/13> - mounirlamouri

*Should we meet at the TPAC F2F if it happens? For how long? Should we host
a WebCodecs discussion?*

   - w3c/picture-in-picture#172 Rename CSS pseudo-class :picture-in-picture
   <https://github.com/w3c/picture-in-picture/issues/172> - beaufortfrancois

*One way of thinking about the future of the Picture-in-Picture Web API is
the ability to actually move an HTML element from a web page to a
Picture-in-Picture window. In that case, the `:picture-in-picture` CSS
pseudo-class name would be confusing for web developers as it would be hard
to differentiate the web page element and the one in the Picture-in-Picture
window.*

   - Autoplay API: update on API shape and editors


   - w3c/media-capabilities#152 Discuss how to reconcile colorGamut &
   transferFunction with ISO 23001-8:2016
   <https://github.com/w3c/media-capabilities/issues/152> - vi-dot-cpp

*Hi everyone. chcunningham@ and I would like to (re)open up discussion with
respect to how MediaCapabilities.decodingInfo() should handle discrepancies
between colorGamut & transferFunction input and and the color information
implicit in mime types like VP9 and AV1. *

   - TextTrackCue: add optional event synchronisation
   https://github.com/whatwg/html/issues/5306

*A proposal to add recommended timing accuracy for TextTrackCue event
synchronization (either as note or a 'should'):
https://github.com/whatwg/html/issues/5306
<https://github.com/whatwg/html/issues/5306>. With implementation changes
to Chromium currently in progress, I think all major browser engines now
achieve the recommended timing accuracy in practice.*

   - TextTrackCue: add unbounded duration
   https://github.com/whatwg/html/issues/5297


*A proposed change to allow TextTrackCues with unbounded duration:
