Attached are the used input .MTS file and the generated .mp4 file.
The video starts with title of 4 seconds build from a JPEG image on track 1 and a Smoke 2 title on track 2

both ffplay and melt give a "invalid" screen for the first 4 seconds.
After this the fragment has the same problem as reported. Note that the
sound of the Geysir doesn't match the image.
