BuildCast Video Player UWP Sample

BuildCast is an end-to-end sample built to showcase the Microsoft Fluent Design System as well as other capabilities of the Universal Windows Platform. It permits browsing, downloading and playback of select video podcasts including a sampling of the most popular ones from Channel 9 as well as some popular Windows tech enthusiast feeds. It has other features such as ink notes, bookmarks and remote playback. This sample was initially shown and discussed at the 2017 Build conference during the Build Amazing Apps with Fluent Design talk.

Features

At a high level this sample demonstrates usage of:

• Fluent design system (Acrylic material, Reveal highlight, Connected animations, ParallaxView, an Adobe XD UX Prototype etc)
• XAML controls and features (NavigationView, swipe commanding, context menu with icons and SVG assets, LoadedImageService, conditional XAML etc)
• Media playback including picture-in-picture and fullscreen views
• Inking and smart ink
• Project Rome and AppServices
• Background download service, Entity Framework and SQLite
• Windows composition APIs (InteractionTracker, implicit animations, scene lighting)
• Notifications with progress bar
• Share contract

• Known issues where there will be code changes have all been moved to issues on github
• Bug fixes

Known Issues

• Download progress reported via toasts / action center will not update when the app quits, even though the download will proceed using background transfer service. This is due to a known platform gap
• Deploying / running BuildCast on a XBOX will result in the app crashing due to a platform bug that is being investigated. More details here.
• A number of warnings have not been addressed
• Things that didn't make it from the Build talk:
  • TreeView control: did not ship in the final Fall Creator's update
  • 360 video playback: this will come in a future update to the app
