mrv2 v1.3.0

v1.3.0

One major new feature and one important bug fix.

• Added tone-mapping of HDR videos. Note that FFmpeg seems to be buggy when reading the frame metadata, so we must rely on the stream metadata only.
  Note that to compile this on Windows, you must install MSVC's shipped clang compiler.

• Fixed tiling behavior (dragging of timeline bar not making view window smaller) which got broken in v1.2.9.

mrv2 v1.2.9

v1.2.9

• Handle AV_DISPOSITION_ATTACHED_PIC properly, instead of skipping it.
• Added PNG decoder so attached png pictures in .wav files are decoded properly.
• Added a File->Save Annotations Only. This allows you to export the annotations as a movie or file sequence.
• Added a File->Save Annotations as JSON. This allows you to export the annotations as a .json file.
• Fixed a crashing bug when drawing freehand.
• Fixed disappearing cursor when selecting a drawing tool.
• Added polygon drawing to the drawing tools.
• Polygon, Circle and Rectangle have two modes (outline or filled now). You select the mode by clicking on each triangle edge of the button.
• Fixed Float on Top on start up on Linux X11.
• Added pip.sh for Unix systems to easily install pip libraries inside mrv2's
  python library directory.
• Moved mrv2's ComfyUI directory to its own repository at:
  https://github.com/ggarra13/ComfyUI-mrv2
  so that it can be listed more easily in ComfyUI's Node Manager AND we
  make it more clear that that project is GPL compatible, not BSD one.
• Fixed selecting montior's Display/View to None from the Menus.
• Updated to OpenUSD 0.24.8 (re-release of mrv2 v1.2.9)
• Updated OpenColorIO to v2.3.4.

mrv2 v1.2.8

v1.2.8

• Automated sourceforge OS automatic file selection for a release (default, the last git release).
• Gain, Saturation and Gamma now effect all videos in a comparison when in Compare Mode.
• A/B Wipe Comparison now properly follows the cursor when zoomed in.
• A/B Wipe Comparison now properly follows the cursor on Y (it was reversed previously).
• Fixed and simplified bakeOCIO.py demo script. Now, you can bake OCIO from the command-line by just doing something like:

  mrv2 <INPUT_FILE> -ics ACEScg -od 'sRGB - Display' -pythonScript bakeOCIO.py -pythonArgs <BAKED.mov>
  

  Note that this script bakes without annotations support so if saving a float EXR to an 8 or 16-bit image, you will get banding.

• Fixed Python Output showing icorrectly in panels when loading a session from the command-line.

• Made UI at start up wider to account for new menus and new language translations.
• Added HDR metadata to Media Information Panel.
• Very minor playback improvement for non HDR videos.

  topbar in OCIO menu.
• THIRD RE-RELEASE: Fixed macOS Intel (amd64) distribution looking for mesa/X11 OpenGL

• Added -otio or -edl command-line option to automatically create an .otio
  timeline from a list of clips (movies or sequences) provided in the
  command-line. Note that FPS is taken to be that of the one with highest
  FPS, so sequences may leave gaps if video clips bigger than their FPS are
  used.

v1.2.1 has been RE-RELEASED on 7/12/2024 to fix a crash when saving movies.

• Fixed codec support (libvpx, dav1d and Svt-Av1) which had gotten broken due
