Did you check the sample? https://reference.dashif.org/dash.js/nightly/samples/drm/clearkey.html

@dsilhavy Yes I have checked with your samples. But our mpd file different from your mpd file. But our mpd file working fine with shaka. Dash player support any specific type of clear key encryption Can you provide any encryption steps with clear key. I struggled more than two days. Please help to rectify this issue

If you host your content (MPD and segments) we might be able to look into this.

Please also keep in mind that you need to host the player on an https server if you are testing outside of localhost. Otherwise EME is disabled

@dsilhavy Issue happened due to clearkey encoding method. I converted key into base64url encode. Then issue automatically fixed Thanks for your response @dsilhavy

const key = a4eb03f8e0928d2e55e37c2fa6afb1ce
const keyId = 12fa7db6feed6dc1c301fc0e66e35fb3
const keyEncoded = Buffer.from(key, 'hex').toString('base64').replace(/\+/g, '-').replace(/\//g, '_').replace(/[==]+$/, '');
const keyIdEncoded = Buffer.from(keyId, 'hex').toString('base64').replace(/\+/g, '-').replace(/\//g, '_').replace(/[==]+$/, '');
