What is the correct syntax to do CENC encryption with ffmpeg?
The ffmpeg 3.0 release notes include "Common Encryption (CENC) MP4 encoding and decoding support", and the files libavformat/movenccenc.h and libavformat/movenccenc.c seem to include everything needed to encrypt MP4 files according to the Common Encryption standard.
However, I can't find any documentation on this topic in the ffmpeg manual pages.
