== Goals ==
== Goals ==
Build a cupcake-sized proof of concept of the larger "Project to second screen" project. This should include the ability to cast a video from a smaller device (phone/tablet) to a larger device (TV).
Develop initial multi-screen capabilities within Firefox, where video content from one device (ie: phone or tablet) can be "projected" in a lightweight (possibly chromeless) browser window (or app?) on a second device.


== Use cases & user stories ==
== MVP feature set ==
TBD
=== Roku player app ===
''Firefox on Roku - final app name TBD''
* The ability to download app from Roku "Channel Store"
* Initial interface on TV
** Introduction page allowing users to discover and learn how to use the feature
** Recent history list
*** Need to figure how which pre-defined Roku screen type to use
*** Also which title to use (video title, page title, URL?)
** Loading screen with title: "streaming XXX" on TV
** Indication of pausing on TV app (overlay a pause indicator on the TV so there is some visual indication that the screen is paused, not just frozen) - pause can be initiated from either mobile device or the Roku remote control
** Go back to Firefox on Roku after finished streaming
*** ie: to the "recent history" list so the user has something to actually to back to (or another screen)
** Show general error messages
*** Failed to download
*** Failed to play


== Technical details ==
=== Android UI ===
TBD
* Fix current bugs
** {{Bug|921924}}, {{Bug|921948}}
* Visual polishing
** visual, micro-copy, icon, size, etc.
* Be able to initiate screencasting from mobile (currently: long-press on video element & item in context menu)
* Be able to pause / play from mobile
 
== Technical specifications ==
* Client app support (first-screen app: Firefox)
** Discover player-ready devices on local network
** Start a new session using video in web content
** Discover an in-progress player session (?)
** Present UI to control player session (play/pause/volume)
* Player app support (second-screen app)
** Launch video from a specified starting position (timeline)
** Play video
