Instant panic on init

[n1ght-hunter]

When calling ffmpeg-next::init a panic is called if the dll aren't available. This seems counter intuitive since a result is returned but ignored. This is a simple example.

fn main() {
    if let Err(e) = ffmpeg_next::init() {
        panic!("Error initializing ffmpeg: {}", e);
    }
}

this would panic with error: process didn't exit successfully: 'target\debug\ffmpeg-testing.exe' (exit code: 0xc0000139, STATUS_ENTRYPOINT_NOT_FOUND)

Ffmpeg version: Version: 6.0-full_build

ffmpeg-next: "6.0.0"
