mrv2 v1.1.0

v1.1.0

• Build fixes.
• Made mrv2's custom file requester list presumed sequences of a single frame
  as a file instead of a custom sequence name display.
• Matched NDI colors.
• Made NDI streams not display thumbnails in any of the panels, as it would
  look like mrv2 had hanged.
• Made installed size and installer smaller, by removing some unneeded python
  libraries used for documenting mrv2.
• Made installed size and installer smaller, by removing Python's unittests.
• Made default Windows' installer not install Python's Tk libraries by default.
• Made default Windows' installer not install IDLE nor turtledemo.
• Overall, the Windows installed size is now almost 150Mb smaller, now at 325Mb.
• Made Windows installer create a registry entry backup for the file
  associations, instead of using an .ini file which was worse. On uninstall,
  the original file association is restored or the registry entry is deleted.
• Added a friendlier name to Windows' Open With RMB menu. Now the version is
  listed, instead of just "mrv2.exe". Also the name in English is provided.
• Added a latest version to Windows' Open With RMB menu. If used, it will
  associate the latest version installed with the file. Upgrading won't
  require you to reset file associations like before.
• Fixed rotations not framing the image even when View->Auto Frame was on.
• Added symbolic links on Windows .exe installer, so that it works more like
  Unix.
  You can use mrv2-v1.1.0.exe to call a specific version of the viewer for
  example.
• Split Timeline into "Timeline" and "Edit" Preferences in Preferences Window.
• Added Default View to "Edit" to select what gets displayed when you hit the
  Edit button ("Video Only" or "Video and Audio").
• Fixed Edit Viewport size when transitions were present.
• Fixed a potential crash when switching to nuke's ocio config.
• Made Python's setOcioConfig accept ocio::// configurations.
• Fixed colors on Python commands being orange instead of dark yellow as before.
• Fixed Python's Panel output, which was not redrawing or scrolling when in Window mode.
• Made View pull-down menu display the full name of the display / view.
• Made UI topbar resize a tad nicer.
• Fixed Python Output in Python Panel which was not refreshing at all due to
  my misuse of the FLTK API since v0.9.3.
• Fixed a stray menu bar on Python Panel on closing it.
• Improved performance of package creation using multithreading when possible
  with cpack's generators.
• Added support for NDI's BT601 and BT2020.
• Added support for NDI's alpha channel.
• Added support for saving PNG and TIFF with alpha channel when saving a half
  or float OpenEXR image. TIFFs will get saved in float. PNG in 16-bits.
• Eliminated duplicated error and warning messages from the logs.
• Improved start up time and sync issues with NDI streams.
• Simplified all parameters in NDI stream to just selecting the source.
• Allowed NDI streams to change size, pixel aspect or color space.
• You currently cannot mix two NDI streams, one with audio and one without.
  Only the first one information will be used.
• You also cannot stream two clips through NDI with different audio
  frequencies or channels.
• Streaming two clips through the same connection after stopping for a while
  can lead to audio stuttering. Either stream them one after the other or
  open a new connection.
• Fixed duplicated FLTK libraries on Linux distribution.
• Fixed framing view while playing (quick re-release of v1.1.0).
• Fixed auto frame view when switching clips of different resolutions (second re-release of v1.1.0)

mrv2 v1.0.9

v1.0.9

• Added a preference setting on Preferences->Errors to control what to do on FFmpeg errors.
• Made the panel drag bar a tad more grey, for a nicer look and more clear distinction when several panels are stacked on the dockbar.
• Fixed a thumbnail refresh issue on mrv2's custom file requester which would show when we save over a previous file. tlRender would cache the file and would display the previous thumbnail before saving. Now it is fixed.

• Added Global USD Render Option parameters which were missing.
• Fixed overlapping of audio labels in Edit window.
• Fixed rotation inverting the coordinates of the annotations.

• Made circle's center also be drawn with float coordinates.
• Added back .wmv/a decoders and asf demuxer in TLRENDER_FFMPEG_MINIMAL.
• Added Video Color Primaries, Color TRC and Color Space FFmpeg information to Media Info Panel's video.
• Fixed FFmpeg reader to take color coefficients. Now the gray ramp of Sam Richards is the same.
• Fixed a bug in session loading when there was no Input Color Space specified
  in the image, which got introduced in v1.0.8.
• Made pen size be able to be 1 pixel making the cursor one line only.
• Made prores_ks (FFmpeg's native encoder) match Apple's ProRes one at 4444p10le. It is now possible to take ProRes4444 encoded files to video editors. THIS IS A BIG IMPROVEMENT!!!
• Upgraded to FFmpeg v6.1.1.
• Improved rotation speed of movies from cell phones, by doing it in OpenGL with metadata instead of with a C++ function.
• Added Creation, Modified Date and Disk Space to Media Info Panel.
• Removed Frame information from Start/End Time in Image Tab of Media Info Panel.

• It is now possible to use OpenColorIO's built-in configs. That is, those stating with ocio://.
• Added a Choice menu in Preferences->OCIO to select any of the three built-in OCIO configs.
• Set ocio default config to the built-in:
  ocio://default
• Fixed a focus issue on Linux when using a draw tool, then typing into one input widget in the toolbar and going back to the view window not ending the draw tool, but continue its trace.
• Fixed Text annotations when image was rotated jumping to the wrong location on confirmation.
• Entering a Text annotation on the viewport can be confirmed by doing SHIFT + Enter.
• Added FFmpeg's actual version information, not just each library.
• Fixed listing of codecs in the About Window.
• Added missing .gif decoder and encoder.
• Added mrv::TextBrowser to allow copying the text in them with a RMB context menu. This is useful, for example, in the About Window for the GPU or codec information, as the full lines get copied, unlike a Fl_Text_Display in which a line can be cut in half.
• Fixed gcc version information in mrv2's About Window. It was showing the GLIBCXX instead.
• Darby simplified and fixed the A/B comparison sometimes getting out of sync.
• Improved the look of HorSlider widget. Now the X to reset to defaults is a tad to the right.
• Fixed selection of Wipe mode which would not work after scrolling in the dock (FLTK bug?).
• Made Compare options automatically frame the view if View->Auto Frame is on.
• Improved the playback performance of the viewer a tad.
• Fixed an OpenGL flickering of the timeline and sometimes of the main viewport
  when the secondary window was opened and then closed.

• Made H264 entry in Save Movie Options panel not show when FFmpeg was built as LGPL.
• Updated OpenUSD to v24.03.
• Fixed <| (go to start) and |> (go to end) buttons not refreshing the button status on playback.
• Added -ics (-ocioInput), -od (ocioDisplay), -ov (-ocioView) and
  -ol (-ocioLook) command-line flags to override the default settings.
  Note that -ocioDisplay and -ocioView must be used together.
• Made OCIO Input Color Space be stored with the image, except when doing
  comparisons in which the first image's Input Color Space is used.
• Made OCIO Input Color Space for each image be stored in session files.
• Made FFmpeg's repeated warnings and errors only show up once in the status
  bar and the logs.

  as I was using an NTFS drive which sets umask 0022 by default.

• Made reading session more robust to handle missing files or wrong settings.

• Made checking for readable files faster.

• Fixed saving large images/movies with annotations on work properly.

• Added a "View/Auto Frame" to turn off auto framing of the view when changing
  from one clip to another.

• Added User Interface->View->Auto Frame to preferences.

• Made saving a VP9 or AV1 with the wrong extension not fail. Instead, they
  are renamed to .mp4.

• Made mrv2's file requester favorites listing automatically remove
  non-existent directories.

• Added GoPro Cineform codec to the list of profiles you can use to encode.
  The biggest benefit is that it can encode at GBRP_12LE and GBRAP_12LE (ie.
  RGB and RGBA at 12 bits with alpha) for a replacement to Apple's proprietary
  ProRes4444 codec.
  It is supported by Adobe Suite (Premiere, After Effects, Media Encoder),

• Improved drawing of Data and Display Window at high resolutions.
• Fixed zooming when Media Information was active on an image sequence.
• Fixed a refresh of mrv2's custom file requester when saving a single image over a previous image file. The icon would not get refreshed previously.
