Vuo 2.0.0-alpha1

The Vuo 2.0.0-alpha1 release is intended for integrators, to get started updating apps that host Vuo compositions. Vuo.framework 2.x is not binary-compatible with Vuo.framework 1.x, so you’ll need to make some changes to your host code. In particular:

• The SDK is now distributed as a macOS Installer Package, which installs to /Library/Developer/Vuo.
• The VuoRunner API has changed:
  • Instead of setting published input port values with individual calls, set multiple at once using the new VuoRunner::setPublishedInputPortValues method.
  • Instead of firing an event into all published inputs, use the new VuoRunner::firePublishedInputPortEvent method to fire an event into only the ports whose values have changed since the previous frame.
  • Instead of waiting for any published output port event, wait for the specific event the host app fired into the composition using the new VuoRunner::waitForFiredPublishedInputPortEvent method.
  • See VuoRunner::waitForFiredPublishedInputPortEvent for an example of updating port values, firing an event, waiting, and retrieving the result — the process for rendering a frame.
• In addition to the existing VuoImage methods, there are some new methods:
  • VuoImage_makeFromJsonWithDimensions
  • VuoImage_resolveInterprocessJsonOntoFramebuffer
  • VuoImage_resolveInterprocessJsonUsingClientTexture
• Subcompositions are now automatically recompiled and reloaded when they change.

See the API reference for the full list of API changes.
