If you are getting ERROR: AtomicParsley type messages in your mythexport.log file, it may be because ffmpeg isn’t exporting the files correctly. One reason for this is that config’s in mythexport that have spaces in the name cause problems. The workaround reported here is to remove the old config, rename it into something that doesn’t have a space, and then re-create the user-job using the new config. (For good measure, I made sure the user-job didn’t have spaces either.) After this, be sure to re-start the mythtv backend to make your changes take effect.
