Trying to use ExoPlayer in Compose Previews currently results in a Render Error, because classes from android.media (e.g. MediaCryptoException) are not loaded in layoutlib.

Marked as fixed.

Fixed on the layoutlib side. The preview in the example provided now works assuming resizeMode and useController are not used (limitations of the ExoPlayer library)
