Important 0.25 Dates
Event Date Changeset
Development Started 10/19/2010 [de679e4]cgitgithub
RC 1 Released TBD TBD
RC 2 Released TBD TBD
Final Release TBD TBD


Important.png Note: This page is actively updated, edited, and modified during the current development cycle (expected to become the "0.25" release). Expect it to change drastically, on a frequent basis, up until the next official release. Items may be added, changed, and removed to accurately reflect anticipated functionality and features leading up to the release date.

Below is an overview of the changes currently in unstable/development code, which will become a future release of MythTV. Some of these changes, most notably the fixes, may have been backported to the 0.24-fixes branch. This is a fairly comprehensive list of significant or noticeable changes that impact the user experience in some way. For every change listed on this changelog, there are many times more changes not listed related to the core framework and inner workings of the software which allow MythTV to do what it does - in other words, what is listed is just the tip of the iceberg.



 

Key New Features

  • Enable certain MythNetvision sources to be controlled via remote(lirc) instead of keyboard/mouse
  • MythMessage, a user messaging interface (replacement for mythtvosd)
  • Web based backend setup utility (replacement for mythtv-setup)
  • HTTP control capabilities for MythFrontend (Currently a Proof of Concept)
  • Support E-AC3, TrueHD and DTS-HD digital passthrough
  • Hardware profiler to help developers understand the user's hardware landscape (opt-in)
  • DirectX Video Acceleration 2 (DXVA2) on Windows (alpha support)
  • New, robust Microsoft Windows build script
  • Add IPv6 support to mythbackend and mythfrontend
  • Stage UPnP client capabilities within mythfrontend - (* disabled while UI is still in development)
  • Add VAAPI support

Major Changes

  • Removed XvMC Support
  • Remove libmpeg2 support for video playback
  • Re-write of API framework (MythXML)
  • Re-write of logging system
  • MythVideo is now part of core MythTV and no longer a seperate plugin

Prerequisite Changes

Minimum version changes
  • Python - Require Python v2.6 or higher (remove support for v2.5)
  • Taglib - Minimum version is now 1.6 or higher
  • Qt - Minimum version is now 4.6.0
Added support libraries/prerequisites
  • Sox - required for nuvexport
  • libxml2 - optional for blu-ray disc metadata parsing (>= v2.6)
  • libudf - optional for detection of DVD and Blu-ray discs without mounting (libudf is also a subcomponent of libcdio)
  • libass - optional for ASS/SSA subtitle support (>= v0.9.10)
  • libfftw3 - optional for new visualization support
    • existing libfftw3 support in configure appears to be a hangover from previous code, it isn't actually used for anything else
Removed support libraries/prerequisites

Special Notices & Instructions

  • Any third-party applications leveraging MythXML will need to write compatibility with the new API framework
