What configuration are you using? What is the output of player.getNonDefaultConfiguration()?

{
"drm": {
"servers": {
"com.apple.fps": "https://license-global.pallycon.com/ri/licenseManager.do"
},
"advanced": {
"com.apple.fps": {
"distinctiveIdentifierRequired": false,
"persistentStateRequired": false,
"videoRobustness": "",
"audioRobustness": "",
"sessionType": "",
"serverCertificateUri": "https://license.pallycon.com/ri/fpsKeyManager.do?siteId=DEMO",
"individualizationServer": ""
}
}
}
}

What did you do?

Try to play this video on Safari.

What did you expect to happen?
Throw error: Shaka Error DRM.REQUESTED_KEY_SYSTEM_CONFIG_UNAVAILABLE ()
Because this stream uses Widevine KeySystem and Safari doesn't support it.

What actually happened?

• If I use com.apple.fps or com.apple.fps.1_0 as the key for DRM-related configurations, the stream plays without video or audio rendering, but the video progress bar is available and displays a duration.
  config like:

{
        "servers": {
            "com.apple.fps": "https://license-global.pallycon.com/ri/licenseManager.do"
        },
}

• If I use fairplay as the key instead, the player throws an error of Shaka Error DRM.REQUESTED_KEY_SYSTEM_CONFIG_UNAVAILABLE (), which is expected.
  config like:

        "servers": {
            "fairplay": "https://license-global.pallycon.com/ri/licenseManager.do"
        },

So my question is:

• When I use com.apple.fps, I think it should throw an error?
• What is the difference between the keys of com.apple.fps and fairplay? I see shaka-player-demo use fairplay but this is not documented if I haven't missed any.
  

Are you planning to send a PR to fix it?
No

If we set useNativeHlsForFairPlay = false the problem does not occur, I'm afraid that Safari when using the native player does not throw any error when the manifest includes a drm that it does not support :( I don't think we can do anything to solve this when using useNativeHlsForFairPlay = true, sorry!

@tykus160 any idea?

We should report it Webkit if that's the case, I'd say video element should throw an error...
