#9255: DNX120 Decoding is broken in FFMpeg and FFPlay (fine in AVID and Adobe
Premiere)

Summary of the bug:
DNX120 decoding/indexing is broken in:
- LWLibavVideoSource
- FFVideoSource
- DirectShowSource (LAV)
- FFMpeg
- Davinci Resolve
The following players also fail to decode it properly:
- MPV
- MPC-HC (LAV)
- PotPlayer
The following software decode it correctly:
- AVID Media Composer
- AVID Media Director
- Adobe Premiere
Here's the mediainfo:

This is how it's decoded in FFMpeg / FFplay:

And this is how it should be instead (decoded by AVID):

Unfortunately, I cannot share the footage of the game (for obvious
reasons, it's a copyrighted event), however I asked them to send me a non-
sensitive content and they put a blue cloth on the camera and recorded a
sample...
I know it kind of sucks as a sample, but here we go:
