Summary0002656: Make DCP verification in player configurable
Description

The full RDD52 verification added with 2.16.x takes a lot of time - most of which is unnecessary if the content has already been created with DCP-o-matic 2.16+. Sometimes, all you need is a hash check, and if possible, multithreaded for all components of the DCP (SSDs are now fast enough to read multiple reels of video and audio simultaneously).
Whereas, when you want to check just data integrity of an external USB connected DCP transport drive after copying or conversion, the full verification can take ages.

Maybe add two separate verification options, or bring up a small dialog which let's you choose between hash check and full verification?

Why not just offer two exclusive radio buttons - 'Perform data integrity check' vs. 'Perform full DCP verification'. And it would speed up verification a lot if it was performed multithreaded. Or maybe offer another checkbox? Because multithreading my actually become slower when performed on e.g. external USB devices.

It's probably not fully solved, but, my main concern with a choice of hash vs. picture asset details checking is solved in recent versions, so, this feature request may be closed. I would probably open another one towards performance optimisation (e.g. multithreading).

Great, thanks.
