I tried to run Av1an docker image on my Ubuntu 22.04 machine with the following:

docker run --privileged -v "$(pwd):/videos" --user $(id -u):$(id -g) -it --rm masterofzen/av1an:latest -i input.mkv

However, the following error occured:

thread 'main' panicked at 'Input file "input.mkv" does not exist!', av1an-core/src/lib.rs:1206:5

The current directory in the terminal is the directory where input.mkv is stored in. So running pwd should have mounted the directory with the input.mkv to /videos. I also set mode for input.mkv to 777 just in case.
