Can't run minimal example : panics immediately #2

Can't run minimal example : panics immediately

I tried running the example provided but it panics immediately with thread 'main' panicked at 'called "Result::unwrap()" on an "Err" value: StateChange(StateChangeError)', examples/minimal.rs:41:18

This error is very cryptic, but I figured it comes from gstreamer directly (gstreamer-0.16.5/src/enums.rs). Does anybody else have the same issue or is it just me ?

Here are the backtraces with RUST_BACKTRACE=1 and RUST_BACKTRACE=full, if it helps :

Nevermind, apparently I hadn't properly installed all of the gstreamer dependencies for gstreamer.rs (I really thought I did though...)!

BTW, thanks for this nice work ! :+1:
