Decrypting AES/CTR video while watching

Question

It is possible to decrypt an encrypted video in AES/CTR and and watching as it was being decrypted?

I want to decrypt Video hosted on MEGA.co.nz and go watching as that goes down without waiting for the download to complete.

I already know how to decrypt, just need to know how to do this gradually in a video

Yes, it's possible. Most video formats and codecs can be decoded in a streaming fashion. For example: MPEG4. AES in CTR mode can be decrypted as a stream.
