Worked for me recording a spin movie with 1.10

Also reported in #18175, by an apparently different user.

comment:3 by Zach Pearson, 4 months ago

I'm not sure why it's working for Eric and not for this user, but I noticed some users also had this problem on the Python 3.13 tech preview build. On that branch, I fixed it by explicitly chmod+x'ing ffmpeg during the build. I have pulled that change into the develop and master branches so a fix is pending for 1.10.1

comment:4 by Tom Goddard, 4 months ago

The 1.10 distribution has execute permission for ffmpeg. So it doesn't seem like giving it execute permission again is going to change anything. Seems more likely this is something specific to the user's computer, maybe some extra security being imposed on by their machines.
