I am currently streaming a set of mp4 (Video) files using AWS S3 Buckets, which is working successfully within the RAB software. It plays correctly when I am in the specific books “Viewer” section as well as when I hit “View in Browser” the video plays.
However, whenever I try to install this APK into an emulator or on a physical device to test, the mp4 does not play at all. The thumbnail shows with a play button on top of it, but pressing the play button does not do anything. Any help or advice would be appreciated. Thanks!
