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 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 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. The API of the two is incompatible.
