gstreamer-net/CHANGELOG.md

+# Changelog
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
+and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html),
+specifically the [variant used by Rust](http://doc.crates.io/manifest.html#the-version-field).
+
+## [0.9.1] - 2017-11-26
+### Fixed
+- Export `FlowError`/`FlowSuccess`, `ClockError`/`ClockSuccess`,
+  `PadLinkError`/`PadLinkSuccess` too
+
+## [0.9.0] - 2017-11-26
+### Added
+- Bindings for (outputting to) the GStreamer logging system
+- Bindings for the GStreamer base library
+- Bindings for all the `Pad` functions to override pad behaviour, and pad task
+  functions
+- Bindings for `StaticCaps` and `StaticPadTemplate`
+- Bindings for `deep-notify` signal on `Object`
+- Support for directly creating `Error`/`Warning`/`Info` `Messages` and posting them
+  from an element with context information (file, line, module, etc.) similar
+  to the C `GST_ELEMENT_ERROR` macro
+- Support for setting custom fields in `Messages`/`Events` during construction
+- Support for creating Buffers out of anything that is `AsRef<[u8]>` or
+  `AsMut<[u8]>`
+- Support for using the `Read` trait on `Adapter`
+- Functions for getting all sink/src/all pads of an `Element`, and all children
+  of a `Bin`
+- Builder for `Caps` and `Structures` in addition to the existing functions
+- `AppSrc`/`AppSink` implement `BaseSrc`/`BaseSink` and `URIHandler`
+- Rust ports of the basic tutorials 1 to 8 from
+  https://gstreamer.freedesktop.org/documentation/tutorials/
+- "Getting started" and "Installation" sections to the README.md
+- "dox" feature for generating documentation for all available configurations
+
+### Fixed
+- `StackTraceFlags` are only available since 1.12
+- Worked around macOS requiring a `NSRunLoop` running on the main thread in all
+  examples and tutorials, to be able to show a window or anything else
+
+### Changed
+- `ClockTime` is now a wrapper around `Option<u64>` to handle the
+  `CLOCK_TIME_NONE` case better. This wrapper implements all the arithmetic
+  and other traits as needed and ensures that no accidential calculations with
+  `CLOCK_TIME_NONE` can happen
+- "Values with format", like in `Duration`/`Position`/`Convert` queries or
+  `Seek` events now return a `FormatValue` type. This contains the actual
+  `Format` together with the value and does any required conversions. This
+  also makes it harder to accidentially mix e.g. values in bytes and time
+- `PadProbeId` does not implement `Clone`/`Copy` anymore
+- Property notify watches return a custom type instead of ulong
+- `Error`/`Warning`/`Info` `Messages` can only be created with specific kinds of
+  `glib::Error` now. Using arbitrary ones does not work
+- `Iterator` bindings were completely rewritten and provide the item type as a
+  generic type parameter now, greatly simplifying its usage
+- All `glib::Values` are now `glib::SendValue` instead, e.g. in `Caps` and
+  `Structures`, as their content must be possible to send to different threads
+  safely
+- `Message::get_src()` can return `None`
+- Allow `None` as `Caps` in `AppSrc`/`AppSink`
+- Allow everything implementing `Into<Option<&str>>` to be used as a pad name
+- Moved `copy()` from `GstRc` directly to `MiniObject`
+- Success/Error enums (like `FlowReturn`, `PadLinkReturn`, `StateChangeReturn`) now
+  implement an `into_result()` function that splits them into a `Result` with
+  the good and bad cases. Also mark them as `#[must_use]` to make it harder to
+  accidentially ignore errors.
+- Error enums implement the `Error` trait
+
+- Many examples use the `failure` crate for error handling now, cleaning up the
+  error handling code quite a bit
+- Lots of other code cleanup, compiler/clippy warning cleanup, etc.
+
+## [0.8.2] - 2017-11-11
+### Fixed
+- Implement StaticType of BufferRef instead of Buffer. Buffer aka
+  GstRc<BufferRef> already implements StaticType if BufferRef does, and
+  without this it was not possible to use Buffers in GValues.
+- Free memory of the appsink/appsrc callbacks with the correct type. It was
+  crashing because of using the wrong type before.
+- Fix documentation URLs in Cargo.toml.
+
+### Added
+- Installation instructions and links to documentation for getting started to
+  README.md.
+
+## [0.8.1] - 2017-09-15
+### Added
+- Implement Send+Sync for Query, Message and Event, and their corresponding
+  Ref types.
+
+### Fixed
+- Constructor for gst_player::Player now works properly with GStreamer 1.12
+  when passing a video renderer or signal dispatcher. There was a reference
+  counting bug.
+- Instead of returning &'static references from functions, return references
+  with a generic, unbound lifetime instead.
+  See https://github.com/rust-lang/rust/pull/42417#issue-233404573
+- Various "unused external crate" warnings and clippy warnings everywhere.
+
+### Changed
+- Remove Cargo.lock from GIT, it's not very useful for library crates.
+- Run everything through latest rustfmt-nightly.
+- Use while-let (instead of loop and if-let) and CLOCK_TIME_NONE (instead of
+  u64::MAX) in the examples.
+
+## [0.8.0] - 2017-08-31
+
+- Initial release of the autogenerated GStreamer bindings. Older versions
+  (< 0.8.0) of the bindings can be found [here](https://github.com/arturoc/gstreamer1.0-rs).
+  The API of the two is incompatible.

+# gstreamer-rs [![crates.io](https://img.shields.io/crates/v/gstreamer-app.svg)](https://crates.io/crates/gstreamer-app) [![Build Status](https://travis-ci.org/sdroege/gstreamer-rs.svg?branch=master)](https://travis-ci.org/sdroege/gstreamer-rs)
+
+[GStreamer](https://gstreamer.freedesktop.org/) (Net library) bindings for Rust.
+Documentation can be found [here](https://sdroege.github.io/rustdoc/gstreamer/gstreamer/).
+
+These bindings are providing a safe API that can be used to interface with
+GStreamer, e.g. for writing GStreamer-based applications.
+
+For background and motivation, see the [announcement blogpost](https://coaxion.net/blog/2017/07/writing-gstreamer-applications-in-rust/).
+
+The bindings (since 0.8.0) are autogenerated with [gir](https://github.com/gtk-rs/gir/)
+based on the [GObject-Introspection](https://wiki.gnome.org/Projects/GObjectIntrospection/)
+API metadata provided by the GStreamer project. Older versions before 0.8.0 were manually
+written and the repository can be found [here](https://github.com/arturoc/gstreamer1.0-rs).
+The API of the two is incompatible.
+
+A crate for writing GStreamer plugins in Rust can be found here: https://github.com/sdroege/gst-plugin-rs

+
+## Installation
+
+To build the GStreamer bindings or anything depending on them, you need to
+have at least GStreamer 1.8 and gst-plugins-base 1.8 installed. In addition,
+some of the examples/tutorials require various GStreamer plugins to be
+available, which can be found in gst-plugins-base, gst-plugins-good,
+gst-plugins-bad, gst-plugins-ugly and/or gst-libav.
+
+<a name="installation-linux"/>
+
+### Linux/BSDs
+
+You need to install the above mentioned packages with your distributions
+package manager, or build them from source.
+
+On Debian/Ubuntu they can be installed with
+
+```
+$ apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev \
+      gstreamer1.0-plugins-base gstreamer1.0-plugins-good \
+      gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly \
+      gstreamer1.0-libav
+```
+
+Package names on other distributions should be similar.
+Please submit a pull request with instructions for yours.
+
+<a name="installation-macos"/>
+
+### macOS
+
+You can install GStreamer and the plugins via [Homebrew](https://brew.sh/) or
+by installing the [binaries](https://gstreamer.freedesktop.org/data/pkg/osx/)
+provided by the GStreamer project.
+
+#### Homebrew
+
+```
+$ brew install gstreamer gst-plugins-base gst-plugins-good \
+      gst-plugins-bad gst-plugins-ugly gst-libav
+```
+
+#### GStreamer Binaries
+
+You need to download the *two* `.pkg` files from the GStreamer website and
+install them, e.g. `gstreamer-1.0-1.12.3-x86_64.pkg` and
+`gstreamer-1.0-devel-1.12.3-x86_64.pkg`.
+
+After installation, you also need to install `pkg-config` (e.g. via Homebrew)
+and set the `PKG_CONFIG_PATH` environment variable
+
+```
+$ export PKG_CONFIG_PATH="/Frameworks/GStreamer.framework/Versions/Current/lib/pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"
+```
+
+<a name="installation-windows"/>
+
+### Windows
+
+You can install GStreamer and the plugins via [MSYS2](http://www.msys2.org/)
+with `pacman` or by installing the
+[binaries](https://gstreamer.freedesktop.org/data/pkg/windows/) provided by
+the GStreamer project.
+
+#### MSYS2 / pacman
+
+```
+$ pacman -S pkg-config mingw-w64-x86_64-gstreamer mingw-w64-x86_64-gst-plugins-base \
+      mingw-w64-x86_64-gst-plugins-good mingw-w64-x86_64-gst-plugins-bad \
+      mingw-w64-x86_64-gst-plugins-ugly mingw-w64-x86_64-gst-libav
+```
+
+#### GStreamer Binaries
+
+You need to download the *two* `.msi` files for your platform from the
+GStreamer website and install them, e.g. `gstreamer-1.0-x86_64-1.12.3.msi` and
+`gstreamer-1.0-devel-x86_64-1.12.3.msi`.
+
+After installation, you also need to install `pkg-config` (e.g. via MSYS2 or
+from [here](https://sourceforge.net/projects/pkgconfiglite/))
+and set the `PKG_CONFIG_PATH` environment variable
+
+```
+$ export PKG_CONFIG_PATH="c:\\gstreamer\\1.0\\x86_64\\lib\\pkgconfig${PKG_CONFIG_PATH:+:$PKG_CONFIG_PATH}"
+```
+
+<a name="getting-started"/>
+
+## Getting Started
+
+The API reference can be found
+[here](https://sdroege.github.io/rustdoc/gstreamer/gstreamer/), however it is
+only the Rust API reference and does not explain any of the concepts.
+
+For getting started with GStreamer development, the best would be to follow
+the [documentation](https://gstreamer.freedesktop.org/documentation/) on the
+GStreamer website, especially the [Application Development
+Manual](https://gstreamer.freedesktop.org/documentation/application-development/).
+While being C-centric, it explains all the fundamental concepts of GStreamer
+and the code examples should be relatively easily translatable to Rust. The
+API is basically the same, function/struct names are the same and everything
+is only more convenient (hopefully) and safer.
+
+In addition there are
+[tutorials](https://gstreamer.freedesktop.org/documentation/tutorials/) on the
+GStreamer website. Many of them were ported to Rust already and the code can
+be found in the
+[tutorials](https://github.com/sdroege/gstreamer-rs/tree/master/tutorials)
+directory.
+
+Some further examples for various aspects of GStreamer and how to use it from
+Rust can be found in the
+[examples](https://github.com/sdroege/gstreamer-rs/tree/master/examples)
+directory.
