Screenberry v3.0.0 Release Notes

Features:

The capability of uploading and using media files in their original formats* has been added to Screenberry. Previously, all uploaded media files had to be converted.

Uncompressed playback support has been added (TGA sequences are now supported). The sequences are sliced during upload to ensure minimum latency during playback start and subsequent rewinding.

10, 12, and 16-bit video processing are now supported.

Cluster support was implemented (experimental)**. Multiple media servers can be synchronized to provide infinite scalability – an unlimited number of displays and playback resolution is now possible. The cluster synchronization can be also employed for calibration.

A new Upload Manager widget has been developed to provide a user interface for uploading multiple media files to the Screenberry media server.

Integration with BlackTrax real-time tracking is now available. BlackTrax is a vision-based system that allows capturing positional data and sending it to the Screenberry media server. The integration is accomplished by the new BlackTrax Motion node added to the node graph.

GenICam (GigE Vision) protocol support has been added with the introduction of two new nodes: the GenICam Camera node is used for calibration and the GenICam Capture node for live streams input.

A new Mask patch node has been developed that enables the easy creation of free-form geometry patches, which can be used to cut arbitrary shapes from the input image.

A new USB Camera node has been added that detects available DirectShow video devices and uses them as input sources.

A Data Item is a new type of item that can be added to the Media Player. It allows the user to animate any parameter of any node by placing such an item on the timeline and changing its length, setting keyframes for it, and changing its value dynamically.

The new Image Format node has been created which allows extracting image format information (image size, number of channels, bits per channel, and whether an image is stereoscopic) in real-time. This feature is useful for advanced automation.

A freeze-frame feature has been added for the media items in the Media Player. The option to hold the frame is available in the media item’s settings.

The Heat Map feature has been added to the node graph. It allows real-time monitoring of performance load and processing time for each node.

A new Smooth Transition node allows gradual transition between changed values of the input parameter over a set period of time.

Improvements:

Main menu

The main Screenberry Panel menu has been rearranged to improve usability and expand available functionality.

The option to show and open Recent Projects has been added to the main menu.

Node Graph

The option to hide unused pins on the node has been added.

Zooming in and out of a node graph has become smoother.

Media Player

New hotkeys have been added that allow playing selected media items (Ctrl + Enter) and playing / pausing current media items (Spacebar). Until now, the Spacebar was used to open a Video Preview window (now the P hotkey is used).

The ability to add transformations has been added for the AUX items.

Seeking using playhead has become more responsive.

Timelines

The timeline user interface in the Media Player widget has been redesigned to improve functionality and usability.

The option to switch between Razor Tool (media item split) mode and Move / Trim mode when editing timelines has been added. Also, now you can switch from Razor Tool mode back to Move / Trim tool (default) using the Esc shortcut.

The following hotkeys have been added to simplify timeline editing:

• Right / Left arrow keys – moving to the next/previous frame.
• Up / Down arrows keys – jumping to the next/previous media item’s beginning/end.
• K / J keys – jumping to the next/previous keyframe.
• Home key – moving playhead to the start of the timeline at the 00:00:00 mark.
• End key – moving playhead to the end of the last item on the timeline or the last marker.

Additionally, holding the Ctrl key enables selecting multiple keyframes in the timeline and moving them simultaneously.

Patch Editor

Geometry and UV view panels have been renamed to OUTPUT and INPUT panels, respectively, and their positions in the Patch Editor have been swapped.

The Patch Editor was thoroughly redesigned to enhance the look and feel and improve the user experience. The following enhancements were implemented:

• A more consistent color scheme.
• Improved displays and patches list.
• Toolbar for operations with displays.
• Rulers.
• Labels of the patches.
• The View Options panel.

Zooming in and out in the Patch Editor has become smoother.

It is now possible to set a reference image and current output image as background images simultaneously and their opacity can be adjusted.

A current server output image preview is updated automatically. This option is enabled by default.

Display Editor

Display size and position are now shown.

The origin of coordinates in the Display Editor is now in the top left corner to be consistent with the Patch Editor.

Now, when a new display array is created, the displays are automatically named Display # instead of just a sequence number. To show the display numbers on the screen, the new test pattern Digits has been added.

The row of command buttons at the top panel has been replaced by the vertical toolbar on the left.

Files widget

Copy, cut, paste, and duplicate functionality has been added to simplify copying and moving files between folders on the server in the Files widget or different instances of the widget. Now, drag-n-drop works for moving files between different folders or moving media files from the Files widget to the Media Player or Media Library.

The current project folder is now highlighted in bold italic.

3D Scene

Texture rendering for 3D models even if UV data for some parts of a model are missing has been added.

The Near Distance parameter has been added to the Free Camera settings.

Now 3D objects can be excluded from projection mapping. This also can be used for masking.

Calibrator

Calibration robustness during the fast Geometry stage was further improved.

A new Calibration in Progress boolean output parameter has been added.

Others

GPUDirect support has been added to the DeckLink Capture node.

An option to disable audio has been added to the NDI Out node.

With TouchEngine SDK updated to version 2021.15810, the TouchEngine node now automatically displays all available parameters for operators with multiple parameters in the combo box.

In the Script node, the getValue() method now returns the index of the multi-value parameter instead of a string which simplifies writing a script.

The Script node now supports the ability to construct output messages which can be used, for example, to simulate a button press or checkbox selection.

The Frame Sync option has been added to the Spout In and Spout Out nodes.

The Sender FPS information parameter is now available in the Spout In node.

A new Watchdog Timeout parameter has been added to the ServerControl node to be able to change the default timeout value of 20 seconds.

Third-party Library Updates:

NDI SDK has been updated to version 5.0.10.

TouchEngine SDK has been updated to version 2021.15810.

The Spout SDK library has been updated to version 2.007h.

The Assimp (Open Asset Importer) Library has been updated to version 5.1.0.rc1.

Deltacast SDK has been updated to version 6.18.

Qt has been updated to version Qt6.

The SDL (Simple DirectMedia Layer) library has been updated to version 2.0.20.

Changes:

Multiple nodes and node parameters have been renamed to improve clarity and legibility.

Localization:

Japanese and Ukrainian languages have been added to the Screenberry interface. The language can be changed in the Preferences > Choose Language dialog box.
