Could you elaborate on how to use that:?

The end result needs to be:
ffplay <file>

that needs to translate to:
ffplay crypto://encrypted_file -decryption_key $AES_KEY -decryption_iv
$AES_IV

I briefly looked at the concat demuxer but couldn't see how to get this
desired result.
If you know how, please let me know!
