Regression: Motion Tracking no longer works
Closed, ResolvedPublic

Description

System Information
Win10 x64, nVidia GTX 1080Ti

Blender Version
Broken: Current Buildbot build and own build
Worked: 2.79RC2

Short description of error
Motion Tracking no longer works. Blender just becomes unresponsive and never starts tracking.

Exact steps for others to reproduce the error

  • Open attached blend file (be sure to also download the MP4)
  • Go to Motion Tracking layout
  • There should be a simple clip (just a moving sphere) and a single tracker
  • Press CTRL+T or ALT+Right Arrow (or click the corresponding button in the GUI
  • Wait... nothing will happen
  • In 2.79RC2 and all other earlier versions of Blender I tried tracking starts immediately
