[FFmpeg-devel] [PATCH] Detect FairPlay DRM protected files and display warning

[Daniel G. Taylor]

Hey,

Attached patch detects FairPlay DRM in mov/mp4/m4a/m4v/m4p files and
displays a warning that the stream decoding will likely fail.

Currently no information is given that a stream is encrypted and the
decoder will just spit out hundreds of errors that don't describe the
actual problem. With this patch it is much easier to see what the actual
problem is.

Take care,
