# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](
and this project adheres to [Semantic Versioning](,
specifically the [variant used by Rust](
## [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
- 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
- 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
- "Getting started" and "Installation" sections to the
- "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
- `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
## [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.
- 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](
The API of the two is incompatible.

# gstreamer-rs [![](]( [![Build Status](](
[GStreamer]( (Net library) bindings for Rust.
Documentation can be found [here](
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](
The bindings (since 0.8.0) are autogenerated with [gir](
based on the [GObject-Introspection](
API metadata provided by the GStreamer project. Older versions before 0.8.0 were manually
written and the repository can be found [here](
The API of the two is incompatible.
A crate for writing GStreamer plugins in Rust can be found here:

<a name="installation"/>
## 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 \
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]( or
by installing the [binaries](
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
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](
with `pacman` or by installing the
[binaries]( 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
After installation, you also need to install `pkg-config` (e.g. via MSYS2 or
from [here](
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](, 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]( on the
GStreamer website, especially the [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]( on the
GStreamer website. Many of them were ported to Rust already and the code can
be found in the
Some further examples for various aspects of GStreamer and how to use it from
Rust can be found in the
