Video File Data Point/Variable Access - What do you need to be able to control?

[CraigWatt]

Okay, so we are currently circling around MP4 Video Container Data Points to see what we can control/dictate what we want either when controlling what a alias 'bucket' CRITERIA should consist of AND what SCENARIO specification we can specify!

Firstly I want to make absolutely clear, what these data points are tied to as far as what 'ffprobe' calls them:

vfo custom names ffprobe data point names
Duration
Size
Video Bitrate
Width
Height
Aspect Ratio
Video Resolution
Container
Video Frame Rate
Web Optimised
Has 64bit Offset
Video Profile
Indexes
Video Codec
Bit Depth
Chroma Location
Chroma Subsampling
Video Codec ID
Video Codec Height
Video Codec Width
Color Primaries
Color Range
Color Space
Color Trc
Frame Rate
Video Level
Ref Frames
Stream Identifier video
Display Title video
Extended Display Title video

Audio Codec
Channels
Audio Bitrate
Language
Language Tag
Audio Channel Layout
Audio Bit Depth
Sampling Rate
Stream Identifier audio
Display Title audio
Extended Display Title audio

Once the above is known, this will help development.

Establishing what this data is (or if this data is unobtainable/empty) improves the control of criteria's and scenario's.
