mrViewer 4.1.2

Bug fixed setting image as background when it was done through the menu in the view or reel window.
Previously, the reel would not get stored and this would lead to a crash.
Bug fixed channel selection on network connections.
Bug fixed gamma setting on network connections, when switching images.
Added cube2ctl.py and 3dl2ctl.py. These are Python ports of the Ruby versions (cube2ctl.rb and 3dl2ctl.rb). They both work practically the same and produce identical output.
Fixed movie files with 3 periods in them being recognized as image sequences when the extension was unknown.
Fixed loading many movies and reaching the maximum of audio file descriptors.
Added optionally saving the metadata for movies.

Bug fixed 3D stereo playback to sync the two tracks on loops.
Bug fixed a sequence detection when files were called 1234.psd or 12345.psd. Now they are treated as single images, regardless. Previously, you had to turn off Preferences/Loading/Load Sequence on File Association & CommandLine.
Bug fixed a nasty crash in audio playback, which would appear when switching images, usually in the background.
Improved looping with audio. No longer audio continues in the background once the last frame is reached.
Bug fixed file requester on multi selections. Previously, using CTRL or SHIFT to multiselect would, in some cases, not load the files once Okay.

Removed the difference between IPTC and EXIF data, as it was never clear. Now they are all called Metadata.
Made int attributes' slider in Media Info Window update when changed instead of when released, except for ripmap/mipmap attribute which remains when released.
Added the missing attribute types (matrices, boxes, etc) to RMB->Add->Attributes panel in the Media Info Window.
Bug fixed timecode parsing of drop frame time code. Valid Examples: 00;01;00;02, 00.01.00.02 or 00:01:00.02.
Added support for multiple video tracks, switching them as you do with subtitles (RMB->Video->Track #).
Added stereo from multiple video tracks in a movie file, when they are the same resolution and have the same frames per second (fps) and duration. You still need to go to the 3D Stereo Window and select the stereo output type.
Bug fixed video/audio/subtitle selection when the codec could not be located.
Added support for OpenEXR's opaque attributes. They are attributes which cannot be modified.

Added saving OpenEXRs with deep data. Note that this mainly copies the file and changes the metadata only.
MrViewer now retrieves all metadata from an OpenEXR file. Note that except for capDate, all attributes are loaded from the first image in the sequence.
Fixed Preferences->Loading->Auto loading of images when changed on disk. Previously, it was a no-op. Now it properly updates the changed image(s).
Added an Update Frame in Cache (shortcut 'u') to update only a single frame in the cache. It reloads the image from disk.
Bug fixed saving of all layers when OpenEXR image had Z and ZBack channels. Previously, this would crash.
Fixed saving of metadata on OpenEXR images with no layers. Previously, no metadata would get saved.
Fixed a regression which was making loading of multichannel OpenEXR images be too slow to update the display.
Added the ability to create/remove/modify the metadata of a movie or OpenEXR image. Use the right mouse button on the Media Info Window to get a menu of options.
Removed the saving of dpx:television gamma in dpx saving as it was gamma'ing twice the image.
Made the OpenEXR attribute 'capDate' be stored and update on every frame.
Improved wandImage saving to save all types of attributes in PNG and MIFF formats only. PSD, TIFF and DPX do not keep the additional attributes.
Note that the current fast PNG reader does not read attributes.
Bug fixed saving of Video attributes in movie files. Note that ffmpeg saves its own set of attributes which cannot be changed (encoder, handler, language).

Made timecode start editable in the Media Info Window. Just type a new timecode and press TAB.
Added creation and removal of IPTC metadata. In the Media Info Window, use the right mouse button and select Add->IPTC->Metadata or Remove->IPTC->Metadata. Allowed to load images which have only a number in them, like: 2304.exr. They are treated as single images, not as sequences.
Bug fixed loading of images that are like: t09.exr, when the image loaded is full content, like: t10.exr. Now they are both properly recognized as t%02d.exr.
Added an option to Preferences->Loading to allow controlling how file asocciations behave when loading a single image or loading it command line. The option is to load the whole sequence or just the image. This is similar to the Drag&Drop option in the same Preferences->Loading.
Bug fixed HUD Timecode display. Previously, the values were wrong.
Bug fixed some memory trashing on the Media Info Window's tooltips.
Bug fixed reading of timecode in OpenEXR pictures.

Made timecode be a separate variable, instead of modifying frame directly. This means:
Frames, Seconds and Time do not take the timecode start into account.
Timecode Drop Frame and Timecode Non-Drop Frame take timecode start into account.
Bug fixed OpenEXR timecode ( "timeCode" attribute ) to work as said in v3.6.6.
Made playback not start at the point of a preloading cache, but from the cursor location (start of sequence usually).
Bug fixed timecode being incorrect.
Bug fixed Opus audio decoding, which would previously raise tons of errors.

Added support for timecode in movies. When a movie with a header entry of "timecode", or a video stream header entry of "timecode" is found, the timecode is interpreted as an offset of the current frame.
Added support for timecode in OpenEXR pictures. When the tag "Timecode" is found, the timecode is interpreted.
Added support for m2ts (AVCHD) [Blu Ray] movies.
Added support for saving OpenEXRs with both Z and ZBack channels in a layer. Previously, the saving would fail.

Added an Override FPS option to preferences. With it, you override the FPS of the sequences to that value set in the preferences. If not active, FPS is tried to be extracted from the image sequence when possible or from the resolution and aspect ratio when not. Finally, if it all fails, it uses the preferences' FPS setting.
Made framesPerSecond attribute in OpenEXRs be read as a string also, to support Nuke saving it as a string instead of a rational number. This setting controls FPS when reading OpenEXRs.
Made film.frame_rate and television.frame_rate in DPX files act correctly as a FPS setting.
Made television.gamma in DPX act correctly as a gamma setting. - Fixed cache line for sequences that did not start at 1.
Made FPS 23.976 a default instead of 23.97.

Made subtitle always use Arial font by default.
Added selection of font for subtitle in the Preferences. Subtitle->Font. It is interactive, you can change it while playing the movie.
Made sequence detection more strict by avoiding common movie extensions.

Allowed file names like MovieFrame####20.png.
In command line, ILM format (not padded) now correctly sets the start and end frame of sequence. So, for example, avatar.61-120.png will set avatar with a start frame of 61 up to 120. Note that padding is not supported in ILM format.
Subtitles now work regardless of the location of mrViewer. We change directories before loading a subtitle file.
Embedded subtitles are now loaded automatically. No need to call Subtitle->Open for them.

Allowed image sequences with more than 4 digits in PNGs. Now up to 9 digits are allowed. Previously, files like: MovieFrame00016.png would get rejected.
Fixed playback of PNGs due to new code seeking incorrectly.
Fixed a crash in Media Information window due to use of an unitialized pointer with PNGs among others.

Bug fixed File->Open->Single Image. It was not doing what it was supposed to do: now it loads a single image and the built-in file requester lists sequences as separate images.
Bug fixed translation of Open Single Image as Abrir Imagen. Previously it would say Grabar Imagen.
Bug fixed yellow line in file requester to always redraw properly and not leave a half line drawn.
Made thumbnail picture never exceed 150 pixels in width.
Turned off multithreading thumbnail creation of file requester on Linux, as it was hanging when switching directories and not all icons had been created.
Removed a minor memory leak in wandImage.cpp (ImageMagick).
Made file requester open in the same directory as last image used in Drag and Drop. This used to work on Windows but not on Linux. Now it works in both.

Bug fixed preload cache of PNGs to do nothing like movie files. This fixes loading of PNGs when they don't begin at frame 1.
Bug fixed a crash when a single PNG was attempted to be loaded. It would raise a floating point exception.
Bug fixed listing and loading frames with no dots as possible frame spec ( %, d, l ) as image sequences. For example, ballred.png. Now the check is more rigorous and they are treated as single images.

Regression - Fixes preloading of image sequences, which would crash v3.5.6 due to a debugging abort().
Added missing ffmpeg utilities to win32 release.
Added missing exr utilities to win32/win64 release.

Made ogg and ogv be valid movie extensions.
Improved the FFMPEG PNG reader to allow it to start at any frame in the sequence.
Made the FFMPEG PNG reader the default one. This makes reading PNGs about five (5x) times faster or more. It largely depends on multithreading, so machines with several cpus or cores will see the more benefit.
