BuzzFeed's Video App - Exoplayer and Adaptive Video
summary
BuzzFeed builds an Android video app using ExoPlayer and serves videos as HLS over DASH for business reasons, implements MVP with a presenter and Kotlin, ships a GitHub sample, and powers an autoplay recycler feed with texture views and a retained-player fragment so rotation stays seamless. Engineering focuses on adaptive streams, validator tools for bad encodes, Gradle/Hugo timing, OpenSTF device farms, and a viral clip that reaches about 4 million views.
