Well... if you're going to use TS anyway and you're happy with the short
key size, that might do.

But IMHO, best thing to do is to create a dedicated stream_filter. Then
the crypto is independent of both demuxers and codecs. Alternatively, write
a codec that only decrypts and then proxies the decoding through a normal
