Playing videos might be easy at first, but this can get tricky when you have to support multiple video/audio formats or offline medias. ExoPlayer2 is here for you! In this session, Julien Salvi will cover the basics of the ExoPlayer, such as how to play a video thanks to the library and its core features. You'll also learn about its architecture, how to set it up, and what video format ExoPlayer supports from classic MP4 to adaptive streams, like HLS or DASH with protected content. A large overview of its capabilities will be highlighted. Then, you will take a look at interesting extensions and features, such as the download manager or the ffmpeg extension for additional audio format support, building playlists, or managing you own DataSource for playing content on SMB servers.
