v1.1.4

This is a major release with big speed improvements and fixes to the color pipeline.

  • On the second re-release of v1.1.4 annotations with blit viewports are possible.
  • On a re-release of v1.1.4 improved OpenGL performance as soon as a clip is loaded and starts playing, when: Window->Preferences->Playback->Auto Playback and Window->Preferences->Playback->Auto Hide Pixel Bar are active.
  • Simplified build scripts.
  • Fixed macOS build issues (fixed in v1.1.3 re-release actually).
  • Prevented a macOS python plug-in issue with Python 3.11.
  • Fixed Wayland support on Ubuntu 22.04.3 LTS and later.
  • Improved performance of OpenGL drawing between 20% and 150%. macOS has seen the most benefit going from playing videos at 4K at 15FPS to 60FPS.
  • Added Preferences->OpenGL->Color Buffer Accuracy to select between automatic, float or 8-bit buffers for speeding up movies or getting more accurate color precision.
  • Added option to select blitting of main viewports for potentially faster OpenGL drawing.
  • Added Windows' stack traces with line numbers for easy debugging.
  • Added Windows' stack traces to be saved into tmppath(). That is: %TMP%/mrv2.crash.log.
  • Allowed pyFLTK be able to compile in Debug.
  • Fixed floating values not respecting float values below 0 or higher than 1.
  • Improved the performance of OpenGL by avoiding OpenGL context switching when not needed (you don't have a text input widget, nor a text annotations showing).
  • Added Linux's stack traces with line numbers by relying on libbacktrace.
  • Improved performance of OpenGL dramatically, particularly on macOS.
  • Improved performance of drawing OpenGL annotations (drawings).
  • Renamed skipped frames as drop frames.
  • Fixed Preview thumbnails above the Timeline crashing the viewer on all platforms.
  • Hide Preview thumbnails when going fullscreen or presentation.
  • Fixed Playlist creation showing an empty view for the first clip loaded. (regression of v1.1.2).
  • Several fixes to Presentation Mode.
