use my own ffmpeg crate This significantly improves safety of the ffmpeg interface. The complex ABIs aren't accessed directly from Rust. Instead, I have a small C wrapper which uses the ffmpeg C API and the C headers at compile-time to determine the proper ABI in the same way any C program using ffmpeg would, so that the ABI doesn't have to be duplicated in Rust code. I've tested with ffmpeg 2.x and ffmpeg 3.x; it seems to work properly with both where before ffmpeg 3.x caused segfaults. It still depends on ABI compatibility between the compiled and running versions. C programs need this, too, and normal shared library versioning practices provide this guarantee. But log both versions on startup for diagnosing problems with this. Fixes #7 2017-09-21 00:06:06 -04:00			`[package]`

upgrade to 2018 Rust edition This is mostly just "cargo fix --edition" + Cargo.toml changes. There's one fix for upgrading to NLL in db/writer.rs: Writer::previously_opened wouldn't build with NLL because of a double-borrow the previous borrow checker somehow didn't catch. Restructure to avoid it. I'll put elective NLL changes in a following commit. 2018-12-28 13:21:49 -05:00			`edition = "2018"`

use parking_lot::Once in ffmpeg I'm getting deprecation warnings for std::sync::ONCE_INIT, and I'm not sure when std::sync::Once::new() became a const fn. Just as easy to switch to parking_lot. 2019-12-28 09:03:05 -05:00			`parking_lot = { version = "0.9", features = [] }`

minor cleanups to ffmpeg build setup * the "lib: {}" print didn't do anything. It turns out that the pkg-config crate emits the necessary metadata for linking automatically. I had the wrong format and didn't notice because something else did it correctly. * gcc::Config is deprecated; the new name is Build. * and the crate is now called cc, version 1.0. Stuff found while looking at #11. Still haven't figured that issue out. 2017-10-24 00:07:07 -04:00			`cc = "1.0"`
