I’m writing a packages that needs to be able to

```julia
run(`ffmpeg ...`)

```

on all three architectures. I looked into [VideoIO’s deps/build.jl](https://github.com/kmsquire/VideoIO.jl/blob/master/deps/build.jl) file and cowered in fear.

Is there any simple way to include a build-dependency on `ffmpeg` so that my package could simply run `ffmpeg`?

Thanks!

what are you trying to do?, according to the ffmpeg self-description it’s

> A complete, cross-platform solution to record, convert and stream audio and video.

and VideoIO seems to be an adaptation of the ffmpeg lib

I need to extract a section from a video file (`.MTS`, `.avi`, `mpeg`, etc), so something along the lines of:

```bash
ffmpeg -i $in -c copy -ss $start -to $stop $out

```

and extract and concatenate parts into one file, so something like this:

```bash
ffmpeg -f concat -safe 0 -i $list_with_video_files -c copy -ss $start -to $stop $out

```

in any case you need to spend some effort:

1. Invent a method for command-line command dependencies OR
2. Learn to do your job with library calls to libavXXX (maybe in a c program) and contribute this to VideoIO.jl

OK, I see. Boo.

So number 2 maybe…

Thanks for the info!
