Test Player Config Output


DRM solutions are available for both HLS and MPEG-DASH adaptive streaming technologies and are configurable via the JW Player Javascript API.

Note that JW Player's DRM support is constrained by what the DRM makers themselves support. For example, Apple supports FPS in Safari on Mac OS, but not in Safari on iOS.
