Important 30 Dates
Event Date Changeset
Development Started 26 Jul 2017 [eb70b88]
30.0 Released 14 Jan 2019 [b26c727]
Final Release TBD N/A

The 30 release encompasses development revisions from [eb70b88] though [b26c727].
The Current Release is 32.0.

Key New Features

Support for mythfrontend running on certain Android devices, including Nvidia Shield and Amazon Fire TV 4K. The application must be side loaded as it is not available in the Play Store or Amazon app store.

Major Changes

Over 500 commits made significant improvements to the infrastructure. For the most part, these are invisible to end users.

Prerequisite Changes

Added support libraries/prerequisites

Use the system provided versions of the following:

libbluray (when >= 0.9.3), libXNVCtrl, libsamplerate, libminizip, liblzo, libhdhomerun

Removed support libraries/prerequisites

Qt4, zeromq, nzmqt

Special Notices & Instructions

  • Data Migration: 30 will only support direct upgrades from 0.22 or higher. If you are running an older version, you will need to upgrade to 0.22, 0.23 or 0.24 then upgrade to 30
  • As always, backup your database before upgrading, see this.
  • Hardware accelerated H.265/HEVC decoding with VDPAU is not available any more for Nvidia users. (This feature may come back in MythTV 31 with the NVDEC extension. In the meantime OpenGL playback is recommended for H.265/HEVC playback. Another option is to stay with MythTV 29, perhaps with the patch in #13211, if surround sound is used, e.g. for German DVB T2 HD.)
  • Python bindings users, note that work-arounds for incorrect times (e.g. off by 1 hour or need to specify time zone) have been fixed. See: [ea500ae]/#13299. It may be necessary to remove those work-arounds.
  • Users that weren't running on the master branch (v30-Pre tag) will need to add a new keybinding. Context=TV Playback, Descriptoin=Toggle Bookmark, Keylist=Return,Enter,Space (this has been fixed as of 2019-04-06. Builds before this still must take manual action.)
  • HDHomeRun tunners are configured differently now, see: Channel Scanning#Scanning with HDHomeRun tuners for details [57a0ad8].
