I was plagued by the Undefined Error when reaching 100% video which was fixed by changing the path to the ffmpeg existing on the server already.
Now I am able to upload a video, but after it finishes, and moves to the approval area, it disappears. When I check my DirectAdmin I can see the files in the ray/modules/movie/files, so they were in fact uploaded, but not converted over and made available.
All folders appear to be chmod'd correctly Using Ad-free Latest Release.
Thanks in advance.
