MFT Exception #8

Open LanceMcCarthy opened 8 years ago

LanceMcCarthy commented 8 years ago

I started seeing an exception in my app that uses the new MFT. I came back here and tried to reproduce it and was successful.

Environmental Facts:

Here are the steps to reproduce:

  1. Start Video MFT example app
  2. Select any effect (editable or static)
  3. Start Recording
  4. The frame will freeze and crash

Here's the debug output the following:

Starting recording...
