I'm surprised by this, as in a previous post you said that you were able to run ffmpeg from the task manager file menu.

What do you have in the stream.converter property? Is it just ffmpeg or is it a full path to the location of your ffmpeg executable? If it is the latter, you need to use the same full path when running the test ffmpeg command.
