Function try_parse_version

pub fn try_parse_version(string: &str) -> Option<String>

Parses the ffmpeg version string from the stderr stream, typically the very first line of output:

use async_ffmpeg_sidecar::log_parser::try_parse_version;

let line = "[info] ffmpeg version 2023-01-18-git-ba36e6ed52-full_build-www.gyan.dev Copyright (c) 2000-2023 the FFmpeg developers\n";

let version = try_parse_version(line).unwrap();

assert_eq!(version, "2023-01-18-git-ba36e6ed52-full_build-www.gyan.dev");
