Description
The current Cineform codec in FFMPEG (version 3.4 at time of submitting this ticket) is not correctly playing back all footage. e.g. https://trac.ffmpeg.org/ticket/6675
Is it possible to use the recently open sourced official Cineform codec (Oct 2017). The goal would be to improve replay quality and to add the ability to encode to this format?

Why set it to wontfix ?
Is it a legal, technical or other reason ?

Could you please explain the won't fix status? It would be very helpful to understand the challenges of adopting the codec.

I'm happy to provide test footage if anyone needs it. This is a very useful intermediate codec for post-production work, rivalling the almost-ubiquitous prores for speed and quality. But unlike proRes it has been open-sourced—something I can't see apple doing any time soon.

Cineform decoder is being improved as part of GSoC.
Cineform encoder can't be incorporated into FFmpeg because it is specific to x86 processors, FFmpeg supports a much wider range of processors than x86.

I don't know if the original suggestion was a good idea or not but it was certainly not fixed.
By 'use' I mean it possible to either assess suitability of directly integrating the codec, or to use information from the repo to improve the existing codec within FFMPEG?
