# nu-ffmpeg
Utility commands for working with ffmpeg in nushell.
## Capabilities
- Return tables from `ffprobe`
- `ffprobe` multiple files at once
- Use `streams`, `streams video`, and `streams audio` to filter `ffprobe` output
- get the `dimensions` of a video stream as a record
- Apply and parse complex filters to a video (Work In Progress)
## Setup
The `ffmpeg` and `ffprobe` commands are required to be installed and available
in your path; they are not installed for you.
Currently only nushell version 0.89.0 is supported.
After that, clone this repository and add the following code to your scripts,
or to your `config.nu` file:
```nu
use <path-to-repository>/ffprobe
use <path-to-repository>/filters *
```
