Sound recorder crash

Hi all,
I'm having some trouble with the sound recorder. I want to use OpenSesame for a basic video elicitation, where the participant watches video and narrates the actions. I've set up the basics in the experiment

But when I run it, it throws an error.


The experiment did not finish normally for the following reason:

Unexpected error

item-stack: video_elicitation_task[run].video_stimuli_loop[run].video_stimuli_sequence[prepare].start_recording[prepare]
exception type: ImportError
exception message: No module named muxer

There's this discussion that indicates my problem has to do with the pymedia-mac combo.

It's over a year old. Have there been any updates on this issue?


  • Anybody?

  • This seems to be the exact same issue as described in 2120, so to avoid fragmentation I'm closing this discussion and replying there.

    There's much bigger issues in the world, I know. But I first have to take care of the world I know.
