allow all cli args to be passed via a json input

[ycmjason]

Hello,

Thank you for this amazing project again!

Currently -metaJSON works great, but it only support meta data. More specifically, I believe -filename can not be specified via it.

In my use case, these metadata and the video is generated via a script. So it would be slightly more ergonomic to be able to specify the filename in the "meta.json" (or maybe we can rename it to config.json?)

Keen to hear what you think!! ❤️

currently i am making a wrapper script that would pass things correctly based on a json that looks something like this:

{
  "filename": "...",
  "thumbnail": "...",
  "meta": {
    "madeForKids": false
  }
}

It's a good suggestion. The internal data structure currently keeps config separate from video meta data, and filename is a bit of a grey area - it's both config & video meta data. One solution would be to introduce a new -config flag which takes a JSON file (config.json like you suggested) containing a videoMeta field

{
  "filename": "....",
  "videoMeta": {
    "(contents of metaJSON)": "..."
  }
}
