I’ve added travis config to this repository: [https://github.com/AndreaCatania/video\_ludo](https://github.com/AndreaCatania/video_ludo) which uses FFmpeg.

I would need to install ffmpeg in order to compile it and so check it. The problem is that I keep getting this error:

```auto
Caused by:

  process didn't exit successfully: `/home/travis/build/AndreaCatania/video_ludo/target/debug/build/ffmpeg-sys-9f435d1442fb53e3/build-script-build` (exit code: 101)

--- stderr

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

```

The ffmpeg installation seems to go fine, but the compiler complain about `PKG_CONFIG_PATH` beeing not set.

If it’s possible to install ffmpeg, how am I supposed to do? or how can I correctly set `PKG_CONFIG_PATH` ?

```auto
sudo: false
language: rust
rust:
- stable
before_script:
- sudo apt-get update
- sudo apt-get install ffmpeg
- rustup component add rustfmt --toolchain stable-x86_64-unknown-linux-gnu
- rustup component add clippy
script:
- cargo fmt -- --check
- cargo build
- cargo test --all
- cargo clippy --all
cache: cargo
env:
  global:
  - TRAVIS_CARGO_NIGHTLY_FEATURE="

Bottom line: install `multimedia-devel`.

I was able to solve my problem using:

```auto
sudo apt-get install libavformat-dev libavfilter-dev libavdevice-dev ffmpeg

```

Thanks!

Thank you for posting this. Solved my problem with an error missing all the lib dependecies while trying to run stable-diffusion-videos github repo. Was getting a pkg-config not found error on Ubuntu 22.04  
running:  
`sudo apt install multimedia-devel`  
fixed it.
