1. Download OpenShot-v3.4.0.AppImage nightly 1. Open terminal 1. chmod +x OpenShot-v3.4.0.AppImage 1. Change directory to location of a valid mp4 1. Run: OpenShot-v3.4.0.AppImage video.mp4 **Expected** OpenShot opens and video is in the list of available items. **Actual** Dialog appears with a warning: > scene-01.mp4 is not a valid video, audio, or image file. This is incorrect, the video plays just fine from the command-line _and_ when imported into an OpenShot track, it plays just fine.
