• Fixed libvpx compilation on Windows which had broken due to an upgrade in
  MSys2's yasm assembler.
• Made compiling FFmpeg on Windows be done in tlRender with MSys2, instead
  of the pre-flight script, so that we can use --enable-zlib and share all
  flags.

mrv2 v1.1.9

v1.1.9

• Made undocking of panels with the dragbar always position them close to the
  panel.

• Added a visual indicator when a panel would dock if released.

  due to incomplete menu items (Windows compiler issue?).

• Fixed Background->Solid Color not getting read properly from the preferences.

• mrv2's custom file requester can now toggle between image previews with the
  preview button (Monalisa).

• Made building FFmpeg on Windows more solid by relying on any of its two
  repositories and if that fails, read it from a tar.gz file.

• Updated About->Update mrv2 to list the changes from the version in a text
  display.

• Improved -pythonScript functionality. It is now possible to change OCIO
  settings, load clips and save out a new movie file with baked OCIO, all
  from a Python script.

• Fixed building mrv2 without TLRENDER_NET and with BUILD_PYTHON ON on macOS.

• Consolidated Python commands to all use "fileName" instead of "file" or
  "filename".

• Added bakeOCIO.py demo script with arguments.

• Added -pythonArgs command-line string to pass a string of separated arguments
  with spaces, like:

  mrv2 -pythonScript mrv2/python/demos/bakeOCIO.py -pythonArgs "/D/pictures/Mantaflow_v09/Fluid.0001.exr 'ACEScg' 'ACES 1.0 - SDR Video' test.mov"

• Fixed drag and drop to work with URIs coming from Google's Chrome when they
  don't have https:// prefixed into them under X11.

• It is now possible to update a single frame of a sequence instead of the
  full cache, by pressing SHIFT+u (Default hotkey).

• Fixed refreshing of thumbnails when cache refresh was requested.

• Fixed Text annotation rendering disappearing after it was entered.

mrv2 v1.1.8

v1.1.8

• Added the ability to load single images from File->Open->Single Image. You can select multiple images but they won't be loaded as a sequence, only as stills.
• Added a command-line setting (--single or -s) to also load single images.
• Removed the 1 pixel padding that was added when first loading a clip full screen.
• Fixed cursor disappearing when going to the action tool dock while a drawing tool was active.
• Fixed libglib-2.0 being bundled in the distribution.
• Added step to check Wayland compatibility for the binary (.deb or .rpm) installers compiled under Rocky Linux 8.9 and fix configuration file if needed.
• Made CMake documentation target (-t doc) not fail if no Python is found.
• Fixed a potential crash when mrv2 was compiled without Python support and a python file was passed as a parameter to the viewer.
• Fixed a potential misdetection of Linux flavor when updating version with:
  Help->Update mrv2 on a system that had both rpm and dpkg installed.
• Added displaying of the icon on the Taskbar under Wayland.
• Made both Python and Log Window start in Windowed mode as defaults.
• Added missing RtAudio's information to About window which was missing.
• Added Preferences->Audio to allow selecting the Audio API to use as well as the Output Device to use.
• Fixed a minor redraw issue on the right side of the pixel bar.

• Fixed X and Y coordinates displaying large negative numbers when no image was loaded.
• Made Preferences->Playback->Auto Playback not activate playback when a clip is dragged for the first time to an EDL playlist.
• Color accuracy for YUV420P movies introduced a minor speed penalty which can make some movies with "Color Space" set to "unknown" performance playback stall, so a new boolean check box setting was added to Panel->Settings->Performance->FFmpeg Color Accuracy to toggle that setting. The default is to have it on as modern movies with Color Space correctly set to "bt709" do not exhibit the problem.
• Fixed an additional bug in resizing window code when loading movies without fixed size.
• Improved resizing window code to try to use the less space possible based on panel bars open and size of image.

mrv2 v1.1.7

v1.1.7

• Made mrv2's custom file requester create thumbnails on demand when they are
  on view. This helps for large files like many big USD files on disk or with
  RAW files which are also slow to load.
• Fixed mrv2's custom file requester thumbnails being too high.
• Added custom RAW and several image missing formats to mrv2's custom file
  requester.
• Started cleaning up FLU's code (mrv2 custom file requester).
• mrv2's v1.1.6 was not respecting the hidden pixel bar on the Preferences
  Window, always showing it stopping.
• Fixed session files starting playback automatically even when the original
  timeline was stopped.
• Fixed a color discrepancy on YUV420 movies being too saturated.
• Rewrote the algorithm for the scaling of the window when the first image is
  loaded (or run from the command-line).
• Fixed a terrible bug on Linux X11 which would sometimes would make the X11
  server reboot on some Linux distros like Rocky Linux 8.9.
• Added OpenRV's license to mrv2 as I took inspiration for their reverse
  playback. I was doing the same on mrViewer, but I had forgotten about it.
• Update tlRender to use OTIO v0.16.0.
• Added what each contributor did so far for the mrv2 project.
  If you don't want to be listed as contributor, not list your email address,
  or something else, please let me know.
• Updated update_mrv2.py script. Tested on macOS, Windows, Rocky Linux 8.9
  and Ubuntu 22.04.4 LTS. From now on, you can rely on automatic upgrades
  if you go to Window->Preferences->Behavior->Upgrades and set them at Startup.
  When you start mrv2, it will check to see if there is an upgrade after 5 days
  of the actual release (so any portential early bugs are squashed).
• Improved translation CMake scripts.
• Added documentation on how to get Wayland working almost flawlessly on Ubuntu
  22.04.4 LTS.
• Added 120 FPS, which drops frames but it is still nice to quickly browse a
  movie.
• Darby's Rec709 coefficients and YUV shader were incorrect leading to subtle
  color shifts. Now they are fixed.
• Fixed shifting clips with annotations when transitions were present.

mrv2 v1.1.6

v1.1.6

This is a release full of goodies and bug fixes.

mrv2 v1.1.6 vs OpenRV 2.0 Speed Comparison:

Life Of Pi 4K 24 FPS Video and Audio Forwards and Backwards

Netflix Sparks 4K 60FPS with Audio except on RV

• ATTENTION:
  This version introduces a change in the way Cache Settings are used for
  movie files.
  The Settings->Gigabytes and the pair of "Settings->Read Ahead" and
  "Settings->Read Behind" are now decoupled.
  In the case of sequences, the Read Ahea and Read Behind will be automatically
  calculated from the Gigabytes settings as before.
  However, for movie files the timeline will only display the settings for
  Read Ahead/Behind, not the actual Gigabytes cache (which can be bigger than
  the read ahead/behind setting). The small Read Ahead and Read Behind is to
  allow playing 4K movies backwards.
  The Gigabytes setting of 0 is NO LONGER USED and will revert to
  4 Gb if set to 0.

• Fixed slow seeking on 4K movies. Now we beat OpenRV on all movies,
  seeking and reverse playback too.

• Improved performance of dragging Tile like the main divider between the
  view and timeline viewport, particularly on macOS.

• Made switching languages keep the UI preferences.

• Fixed cross cursor when entering the view area and coming from the draw
  tools or the drag bar.

• Made drag bar change color besides changing cursor to indicate you can
  drag it.

• Fixed NDI playback with audio which had gotten broken on v1.1.1.

• Improved .githook to run dos2unix to avoid dummy commits due to Windows'
  CR returns.

• Fixed window resizing calculation that had two ugly bugs in it (thanks
  to ManoloFLTK for having dealt with my ugly code!!!). Now resizing of
  the main window takes the dock properly into account.

• Fixed auto hiding of the pixel bar from the preferences switched is changed
  and okay'ed while the movie is still playing.

• Fixed seeking on the timeline on Linux sometimes getting the event
  incorrectly on X.

• Fixed starting a movie with loop on and playing stopped and then start
  playing it backwards.

• Refactored playback code and fixed playback buttons sometimes getting out of
  sync compared to the command-line flags passed.

• Created Preferences->User Interface/Thumbnails to select the places
  where thumbnails appear. Currently can be above the Timeline and in the
  Panels.

• Changing languages now stores and re-loads a session on a temporary location,
  so the interface does not reset to 0.

• Made the timeline thumbnail a tad smaller and more polished.

• Fixed a potentially nullptr pointer de-referencing when OpenGL accuracy was
  set to Automatic.

• Worked around an UI redraw issue on Wayland.

• Fixed timeline interaction (dragging clips in .otio timeline) in 1.1.5
  re-release.

• Fixed macOS issues when showing and hiding the timeline bar.

• Made View Window / Timeline Viewport divider highlight in a grayish color
  when it can be dragged.

• Made Panel divider highlight in a grayish color when it can be dragged.

• Fixed cursor when dragging on the Panel divider bar.

• Fixed cursor sometimes switching to the Arrow instead of the Cross cursor.
  This was maily a Linux issue.

• Fixed background transparent color being lighter on Wayland.

• Added Cache Use and Cache Percentage to HUD's Cache display.

• Made Edit button turn on/off automatically according to the size of the
  timeline viewport.

• Added default sensible Window settings for UI panels when in window mode.

• Made Window settings for UI panels get saved even if they were in panel mode.

• Fixed .otio markers display in timeline viewport.

• Fixed size of Timeline Viewport when in Edit mode on macOS. Now it resizes
  properly.

• v1.1.6 on Linux was re-released on May 16th, 22:00 Argentinian time (-3 GMT)
  to fix an X11 rebooting bug when going to Presentation Mode.

mrv2 v1.1.5

This is a critical update for Windows, Linux and macOS users.

It was re-released on May 6, 16:20 PM Argentina time.

It is a bug fix release for the regressions in v1.1.4 and early versions of v1.1.5 which were rushed:

• Added a FAQ on the documentation about Linux XWayland and Wayland on
  why it could make playback slow if your OS was not configured properly.
• This is the first version that supports Wayland and XWayland.
  For instructions on how to set XWayland and Wayland on Ubuntu 22.04.4 LTS
  with NVidia drivers, please see Help->Documentation the FAQ section.
• Fixed annotations not showing when Blit Viewports was on.
• Fixed hiding of pixel bar sometimes failing even when:

  which would crash Wayland.
• mrv2 can now be built with the pre-installed python, without having to
  build python itself. Of course, in that case, mrv2 cannot be re-distributed.
  Tested on Linux and macOS only for now.
• Added a python translating system for plug-ins.
• Translated all update-mrv2.py strings into Spanish.
• If using blit for the viewports, automatically switches to shaders if
  Background is transparent and image has transparency, as glBlitFrameBuffers

  .svg icons.
• Fixed Edit Viewport Clip Info and Device Info not respecting the device
  pixel ratio when the Edit button was pressed.
• Fixed macOS crashes with preview thumbnail.
• Fixed timeline redraw issues.
• Respect last configuration of Timeline/ClipInfo and Timeline/TrackInfo.
• Removed debugging statements from Linux packages on a re-relase.

• Fixed a compilation issue between FLTK's JPEG libraries and those of
  libjpeg-turbo on Linux.
• Fixed Right Mouse Button toggling off the audio when there had been a drag
  action with some other button before.
• Fixed a precision problem when shifting annotations at the beginning of a
  clip due to a following clip being dragged to the same place as the
  annotation.
• Improved performance of timeline drawing when annotations are present.
• Fixed refreshing of image sequences
  (ie. Files Panel->Select Image->RMB->File/Refresh Cache) when there were
  missing frames and later they were added. It used to work in v1.0.0 but a
  change in tlRender broke it.
• Updated mrv2 to Python 3.11 to conform to the VFX 2024 Platform.
• Python 3.11 on Windows is now built with optimizations on.
• Updated mrv2's glfw3 to 3.4.

  (needs v0.2.2 at least).

mrv2 v1.1.1

v1.1.1

• Added keyboard shortcuts for Render/Video Levels and Render/Alpha Blend.
• Added support for multiple audio tracks. You can switch from one to the
  other by selecting the Audio button (the speaker icon) with the
  Right Mouse Button and selecting a track.
• Fixed audio metadata in audio section of Media Info Panel for each audio
  stream.
• Added missing video metadata in video section of Media Info Panel.
• Improved speed of refreshing of a clip (when switching audio tracks or using
  View->Ignore Display Window).
• Made movies longer than 30 minutes with multiple audio tracks, use a short
  read ahead / read behind or switching audio would be too slow.
• Fixed saving movies with annotations and with an alpha channel.
• Fixed saving movies with annotations at half or quarter resolution.
• Fixed an ugly bug on Linux when saving movies with annotations repeating
  every other frame (ie. saving on two's).
• Fixed line error reporting in Python's Output (pybind11 bug).
• Added Editor/Jump to Error to Python Panel. You can select the line of the
  error in the Python output and the Editor will jump to the offending line.
  If you don't select anything in the Python output, it will jump to the last
  error counting from the bottom.
  It will skip errors from files that are <frozen ...>, like importlib.
  If the error is on a file and not from the Python Editor, mrv2 will try to
  open an external editor and jump to the line of it.
  The editor to use is taken from the EDITOR environment variable first.
  If not set, mrv2 will try to use one of the popular editors. Its defaults
  supports the syntax for emacs, gvim, vim, VS Code, notepad++ and nano.
  The preferred editor is checked at start up based on what you have installed
  on your PATH and whether you are running interactively or also have a
  terminal.
  Visual editors are given preference over terminal editors.
  Of course, you can edit the editor with Python Panel->Editor/External Editor.
• Fixed Python error reporting in the Python Output of the Python Panel for
  mrv2 python plug-ins.
• Fixed message that said it was saving a movie without audio when saving
  a sequence of frames.
• Fixed reading of FPS from OpenEXR images as they are now rational instead of
  a double.

  sequence did not start at 0.
• Fixed a minor bug using snprintf of int64_t with an int specifier.
• Improved the main web page for mrv2.
• Fixed translation of "Color" in Panels. Of course, since English and
  Spanish use the same word, this still makes no difference :D!
• Fixed the name of the video stream in the Media Info Panel to be like the
  layer name listed in the Panels and in the Color Channel pull down.
• Added back truehd decoder and encoder which were removed from
  TLRENDER_FFMPEG_MINIMAL compilations.
• Sped up redrawing when the Media Info Panel was open, as we know refresh
  only the tabs that change.
• Fixed changing the first and last frames from the Media Info Panel.
• Modified int sliders to use HorSlider instead to make it consistant.
• Fixed (very slow) changing speed from the Media Info Panel.
• Fixed HorSlider resizing improperly when values were bigger than 10000 or
  smaller than -10000.
• Improved precision when accepting or editing text with a zoom factor or
  pixels_per_unit different than 1.
