Unable to build [no variant or associated item named / no field `time_base`]

[mailhost]

Cool project and would like to give this a try, just having a build failure.

podman run -ti --entrypoint=/bin/bash docker.io/library/rust:1.66.1
apt install libavutil-dev libavformat-dev libavfilter-dev libavdevice-dev libclang-dev
cargo install --git https://github.com/russelltg/wl-screenrec

as well as...

git clone https://github.com/russelltg/wl-screenrec.git
cd wl-screenrec
rustup toolchain install stable-x86_64-unknown-linux-gnu
rustup run stable cargo build --release

Yields

Compiling wl-screenrec v0.1.0 (/build/wl-screenrec)

Interesting, what ffmpeg version is this?

[russelltg]

Can repro in that container

[russelltg]

The first one is fixable, and I should be able to fix it in the next few days. But I think I require libavutil >= 57, and that container has 56.

Very good, I have it built and working now with ffmpeg-5.1.2 (libvutil 57). Looks I was building with ffmpeg-4.4.3 previously.

Excellent!
