Vuo 2.1.0

Vuo 2.1.0 adds several new features and fixes several community-reported issues. Highlights include:

• Send and receive video via NewTek NDI® (Vuo Pro)

• Fixed-height (in addition to fixed-width) image layers and objects
• OSC wildcard matching
• New Change Window Level node
• New nodes for manipulating binary data
• Expanded documentation, more example compositions, and more example SDK code

Read on for all the details.

Built-in Nodes, Types, and Input Editors

• Added the ability to send and receive video via NewTek NDI®:
  • Send NDI Video (Pro)
  • Receive NDI Video (Pro)
  • List NDI Sources (Pro)
  • (Thanks to the many people who requested this!)
• Added Send RTMP Video node (limited to 1280x1280 pixels in Vuo CE; unlimited resolution in Vuo Pro)
• Color:
  • Added Make ICC Color and Get ICC Color Values nodes to convert from/to a color specified using components in an ICC profile to/from sRGB (Thanks to @Bodysoulspirit for requesting this!)
  • In Make CMYK Color and Get CMYK Color Values, added a Colorspace port to allow selecting a different method of converting between CMYK and sRGB (Thanks to @Bodysoulspirit for requesting this!)
• Image:
  • Added Skeletonize Image node (Pro)
  • In Find Faces in Image (Pro), added Landmarks output which includes points for eyes, nose, and mouth, and a Get Face Landmarks node to retrieve them (Thanks to @marioepsley for requesting this!)
  • Fixed issue where Resize Image showed garbage (rather than transparency) in the letterbox/pillarbox areas when in Fit mode
  • Fixed issue where Blur Image showed garbage (rather than transparency) around the edges when “Expand Bounds” is enabled
• Window:
  • Added Change Window Level node (Thanks to @carlitos and @micpool for requesting this! — 1, 2)
  • Added Get Window Screen node (Thanks to @alexmitchellmus and @micpool for requesting this! — 1, 2)
  • Fixed crash when using Change Window Size with the Pixels unit and dragging the window between a Retina and non-Retina screen (Thanks to @Scratchpole for reporting this!)
  • Replaced Get Window Dimensions with a new version with a Unit input port and simplified output ports, and also output the window’s screen position
  • Renamed Change Screen to Change Window Screen for clarity
• Math:
  • In the Scale node, added support for integers
  • In the Average node, added support for integers and points
  • In the Find Minimum/Maximum, Keep Minimum/Maximum, Keep Average, Is within Range, Are Equal (Number), Are Not Equal, and Multiply nodes, added support for points
  • Renamed Are Equal (Number) to Are Equal (Math) now that it supports points
• Data:
  • Added nodes for manipulating binary data: (Thanks to @dr.drainaway for requesting this!)
    • Make Data from Bytes
    • Get Data Bytes
    • Append Data
    • Cut Data
  • Fixed crash when using Fetch Data and the web server provides the Content-Type HTTP header without any actual data (Thanks to @jandraka for reporting this!)
  • Added Became Greater/Less Than nodes
• In Make Image Layer (Scaled), Make 3D Object from Image, and Make Unlit 3D Object from Image, added the ability to specify a fixed height (Thanks to @MartinusMagneson and @Bodysoulspirit for requesting this!)
• Extended OSC Filter by Address to support wildcard matching (Thanks to @micpool for requesting this!)
• Fixed crash when receiving MIDI SysEx messages (Thanks to @micpool for reporting this!)
• Fixed issue where audio input/output devices would sometimes incorrectly show “Default” in port constant flags on the editor canvas, when a specific device is actually selected (Thanks to @Joëlle for reporting this!)
• In Display Console Window, added a Clear port and menu item
• In Append Texts, added an Include Empty Parts port
• In some Send * nodes, moved the port actions to the top for greater emphasis
• Updated to Blackmagic SDK 11.5.1

Exporting Apps and Plugins

• Fixed issue where some compositions exported as screensavers and FFGL plugins would show stretched pixels along the edges of the viewport
• Fixed issue where compositions exported as screensavers couldn’t find their bundled resources when run on macOS 10.15

Vuo Editor

• When exporting FFGL, screensavers, and FxPlugs, added a link to open a Finder window showing the exported plugin (Thanks to @solidsatetav for reporting this!)
• When zooming in to Actual Size, the view is now centered on the selection
• Added the ability to drag and drop ICC files from Finder onto the editor canvas
• In the “Welcome to Vuo” window, added an “Open a Composition” button
• Improved reporting of compile/link errors in 3rd-party nodes
• Improved rendering of linebreaks in text port constant flags
• Fixed issue where moving the mouse (without clicking or dragging) could sometimes cause the editor canvas to move
• Fixed issue where the port popover for a published input port didn’t always show up-to-date values
• Fixed issue where the toolbar’s zoom icons could get out of sync with the menu item and actual zoom state
• Fixed crash when encountering some compile/link errors in 3rd-party generic nodes
• Fixed crash when running a composition with a custom generic node with an unspecialized port
• Fixed crash after adding a new input port to a GLSL shader while it was running
• Fixed crash when saving a new shader file
• Fixed crash when opening some compositions with missing nodes
• Fixed occasional crash when searching the canvas
• Added debugging information about interface languages
• Added debugging information about plugin/app exporting
• Fixed minor memory leak when searching the canvas
• Fixed minor memory leak when exporting screensavers
