6001 - Shaka Error Drm.requested_key_system_config_unavailable () |verified| -

player.getNetworkingEngine().registerRequestFilter((type, request) => { if (type === shaka.net.NetworkingEngine.RequestType.LICENSE) { // Ensure the correct license server is used per key system if (request.uris[0].includes('widevine') && !window.navigator.requestMediaKeySystemAccess) { request.uris[0] = request.uris[0].replace('widevine', 'playready'); } } }); Finally, she added a user-friendly message for when all DRM systems fail:

Maya opened her browser's developer console and replicated the error. She saw the player trying to initialize a DRM system called "com.widevine.alpha" (the standard for Chrome and Firefox) but failing because the video file was actually encrypted for a different system: "com.microsoft.playready" (common in older Edge browsers). "Our biggest subscriber, a film critic named Dr

Maya opened her laptop and pulled up the logs. The error was specific: 6001 - shaka error drm.requested_key_system_config_unavailable She knew Shaka Player—it was the heart of their video system, a powerful JavaScript library for adaptive streaming.
