Fixed in Vuo version: 

OS version: 

  • OS X 10.11

How severely does this bug affect you?: 

●●●○ — It prevents me from completing a specific task with Vuo.

Steps causing the bug to occur: 

  1. Create simple video player composition. With and vuo.image.render.window
  2. Set Hap -encoded video as video URL
  3. Run composition -> Everything works (attached image: ScreenShotHapBug2.png)
  4. Export composition to Mac App
  5. Run exported mac app -> Video is not displayed (attached image: ScreenShotHapBug1.png)
  6. Check OSX error console (attached image: ScreenShotHapBug3.png)
  7. Do the same with other video types (at least h264) -> Works fine

Have you found a workaround?: 

No - only other codecs works (at least h264)

Other notes:

I have HAP-codec on my system

I have HAP-codec on my system and it works with other software (VDMX, Compressor...). I guess HAP -codec is needed to view HAP-videos even in the Vuo-editor (which works)?

And I tried to reinstall it, doesn't help.

Do HAP-video player work on your system when composition is exported as standalone app?

Confirmed, there is a problem

Confirmed, there is a problem with Hap playback in exported apps. We'll get this fixed.

Workaround in the meantime:

  • Right-click on the exported app, choose Show Package Contents, navigate to Contents > Frameworks > Vuo.framework, and create a new folder called "Frameworks".
  • Right-click on Vuo, choose Show Package Contents, navigate to Contents > Frameworks > Vuo.framework > Versions > 1.2.6 > Frameworks, and copy HapInAVFoundation.framework to the folder just created in the exported app.
