In this form, it can be played by Chrome with Widevine / Edge with PlayReady etc. The nginx module we maintain (https://github.com/kaltura/nginx-vod-module/) can perform this repackaging on the fly. If the file is encrypted on disk with the same key that should be used for playback, it will skip the encryption / decryption and serve the data as is (if the keys are different, it has to decrypt + re-encrypt) > thanks! > > -compn Thanks !
