• Fixed sequence of images detection when there was an image with the same
  basename, directory and prefix but no number.
• Fixed the RAW image reader to handle images that are smaller once decoded.
• Fixed RAW reader not supporting LCMS2 nor jasper. Now they are supported on
  all platforms.
• Added Sigma .X3F RAW support to RAW Reader.
• The RAW Reader properly reads all files but two from:
  https://www.rawsamples.ch
• Fixed an OpenGL refresh/redraw issue when going to the Preferences
  Window and returning with new settings. It could also provoke a crash on
  Windows.
• Made the Log Panel not save its visibility upon program exit. This prevents
  the Log Panel Window from opening on a new start up of mrv2 as it is usually
  not wanted, but happens once there had been an error in the previous instance.
• Linux uninstall with DEB and RPM has been improved. Now, instead of just
  removing the symlink of /usr/bin/mrv2, the symlink is changed to point to the
  latest version installed if any.
• You can now open only one instance of the viewer and new images opened will
  be sent to the already opened viewer, instead of opening multiple instances
  of the viewer. You set the behavior in:

Preferences->User Interface->Single Instance.

• Removed all warnings and errors from the Sphinx documentation generation.
• Fixed positioning of text editing when re-editing a text annotaion.
  Previously, it could be offset quite a bit if the zoom was not 1.
• A lot of source code clean up from mrViewer's bad and old source code.
• Windows installer now will remove the file association first before replacing
  it with the one of mrv2.
• Made executable smaller on all platforms by using dead-code elimination.
• Added pyFLTK bindings to the distribution. It is now possible to create
  FLTK windows with Python and control and access mrv2's windows with it.
• Added Find and Replace to Python Editor in the Python Panel.
• Added Comment and Uncomment region to Python Editor in the Python Panel.
• Made focus selection on the main view window not work upon just entering.
  This solves the issues with losing focus on the Frame, Start Frame and End
  Frame widgets. It also fixes problems when showing a Python window which
  would otherwise not stay on top.
• Added Save/OTIO EDL Timeline to the menus.
• Allowed Saving OTIO Timelines of single clips and other .otio files.
• Build system changes and fixes:

  • Renamed runme.sh script to runme_nolog.sh.

  • Added a new runme.sh script that calls runme_nolog.sh but saves the compile log into BUILD-KERNEL-ARCH/CMAKE_BUILD_TYPE/compile.log.

  • Updated windows build script to work with MSVC 2022, not just 2019.

  • The Windows compilation takes advantage of Msys to install the dependencies of libintl, libiconv and gettext.

  • Added --help flag to runme.sh to list all the possible settings.

  • All bash commands are run with run_cmd which prints them and times them.

  • Added optional build support for all the optional TLRENDER_* settings and for the MRV2_* settings. It is now possible to build a light version of mrv2 or one with all the features.

  • Fixed a problem with the embedded python (pybind11) locating the system Python installation instead of the local one instead. This created havok on my Ubuntu 22.04 when there was an upgrade.

  • Made parsing of -D options like -D TLRENDER_USD=OFF work with or without a space.

  • Got rid of the default compilation of Gettext on macOS, replacing it with a pre-compiled libintl.dylib.

  • Made the build system automatically release beta versions of the software after each successful compilation on the beta branch. You can now download the latest beta binaries from:

    https://sourceforge.net/projects/mrv2/files/beta/

mrv2 v0.7.8

v0.7.8

• Added a hotkey selection to switch pen colors.
• Fixed hotkey search highlight redraw showing the wrong hotkey.
• Made pen size be adjusted to match the resolution of the image.
• Made eraser pen size be twice and a half the pen size by default for easier
  drawing and erasing without having to bring the annotation panel.
• Made saved color presets in the color picker be sorted from top to bottom,
  where the top color is the last one used.
• Added saving the old color to the preferences.
• Fixed saving current EDL through Python API.
• Added a command-line switch (-resetHotkeys) to reset hotkeys to their default.
• Added a button in Settings to reset hotkeys to their defaults.
• Python API now supports Playlists again with a new API.
  You can add new clips to an EDL playlist, list all playlists,
  select a playlist based on its index, its name or its item
  and save the selected playlist.
• Made FileItem paths read-only in the Python API.
• Fixed the beginning of English playback documentation which was in Spanish.
• Improved the User Documentation.
• Fixed name of some hotkeys in Spanish locale.

  compile all the GNU-like dependencies (FFmpeg, libx264, libvpx and liblcms2).
• Added x264 to the Linux and macOS builds but it is turned OFF by default.
• Made right mouse button text size match that of the main menu bar.
• Fixed Preferences->Playback->FPS not doing anything. Removed
  Preferences->Playback->Override FPS.
• Added a way to edit baked Text Annotations from a frame.
  If you click with the Right Mouse Button on the Text tool, a pop up Window
  will appear displaying a pull down with all your text shapes for the
  current frame. Selecting one, and clicking on Edit Text will take you to
  the Text widget where you will be able to reposition it, re-edit it, etc.
  This also works in network connections.
• Made text widget font size be dependant on the render size of the image.
• Improved scripts in bin/ directory with help messages.
• Moved python scripts in bin/ directory to bin/python.
• Improved runme.sh script to accept a -gpl flag to compile FFmpeg with libx264
  support in GPL mode on all platforms. The default is still to build a LGPL
  FFmpeg without libx264 saving support as that complies with the BSD license
  of mrv2's source code.
• Improved README.md build instructions to document the optional building of
  FFmpeg.
• Fixed saving movies when saving without annotations leading to bad redraws
  later on in the timeline.
• Fixed resizing of window when an image is loaded or the Fit Window to Image
  button is pressed. Now it will correctly zoom to 1 if it fits it.
• Made tiling slider of Timeline Viewport darker so it is more visible.
• Fixed order of clips loaded from the command-line being in reverse order.

• Fixed drag and drop on Windows only allowing to load 4 clips before not
  allowing drag and drop to work anymore.
• Fixed file requester hanging when reading .py files in a directory.
• Updated to OpenEXR 3.2, OpenColorIO 2.3.0, etc.

  easily choose from them.
• Added two colors to drawing tooldock. You can switch between them with the
  arrows that point to them.
• Wipe Comparison is now fixed which had gotten broken in v0.7.5. Thanks to
  Darby Johnston.

mrv2 v0.7.6

v0.7.6

This is mainly a bug fix release to Edit features and general issues found
with v0.7.5.

  the Preferences->Errors->Do Nothing was set.
• Fixed copying frames from one video to another even when they have different
  frame rates.
• Added an option in Preferences->Timeline to remove the EDLs from the
  temporary directory once the application exits.

mrv2 v0.7.5

v0.7.5

Playlist and Editing

This is the first version that supports some basic editing and improves upon
the playlist panel by making it interactive.

• The Playlist panel's functionality has been simplified. It is there only to
  create an empty track or start a new EDL with one clip from the Files Panel.
  The in and out points are respected when the clip is added.
• Added an Edit/Frame/Cut, Edit/Frame/Copy, Edit/Frame/Paste and
  Edit/Frame/Insert to cut, copy, paste and insert one frame (video and audio)
  of any media. Currently, it does not support transitions, that are removed.
  As soon as one of these commands is used, a new EDL is created.
• Added an Edit/Slice to cut a clip in half at the current time location.
• Added an Edit/Remove to remove the clips that intersect the current time
  location.
• Added Drag and Drop functionality to the Files Panel into the Timeline
  Window as well as to the Playlist panel to add clips and create an EDL.

mrv2 - part 11 - v0.7.0 new features

mrv2 v0.6.4

v0.6.4

• Improved Python plug-in API. Now plug-ins are defined with a base class,
  and menus with a dict (without tuples) like:

  Help->Documentation. The environment variable used to look up plug-ins is:

  MRV2_PYTHON_PLUGINS

  It is a list of colon (Linux or macOS) or semi-colon (Windows) paths.
  Plug-ins are defined, like:

  class Plugin:
      def hello(self):
          print("Hello from plug-in!")
  
      def menus(self):
          menus = { ("New Menu/Hello", self.hello) }
