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

 {
    drm: {
        clearKeys: "2b9f95f1b74e4103abf139404d6dc262": "8b0895fe9b8129d1e618a80ab03d3804",
    },
    streaming: {
        startAtSegmentBoundary: false,
    },
    manifest: {
        dash: {
            ignoreSuggestedPresentationDelay: true,
            ignoreMinBufferTime: true,
        },
        defaultPresentationDelay: 8,
    },
}

What did you do?

1. Specify clearKeys for a DASH manifest in the DRM config
2. Load the MPD and attempt playback

Playback succeeds on 4.6.18 but fails on any newer version.

What did you expect to happen?
Normal video playback

What actually happened?

The manifest loads but the video does not play.

Are you planning to send a PR to fix it?
Honestly not sure where to start here to fix it, so no.

If I use disableAudio everything works fine, if I use disableVideo the problem occurs.
