The DVD contains a VOB (VTS_03_0.VOB) that is not accepted by the FFmpeg API. It contains a video track only, but it is detected as invalid track:

This causes the transcode to fail.

It turned out that the DVD had CRC errors. Using a different DVD reader (that did not report CRC errors) fixed the problem.

So all work as designed: A defective source file should be reported to the application that accesses it via Fuse. Closed.
