It seems you are right. I had noticed some time ago that the duration of Ogg
files was underestimated, and your patch seems to fix it on the one I just

Real length:                17:34.83465
Reported by current ffmpeg: 17:34.64
Reported by patched ffmpeg: 17:34.82

I am not oggdec's maintainer though.
