--- Begin Message --- HAve you tried to replex it with another multiplexer (mplex for instance) ? I have previously seen ffmpeg and mencoder output result in the "waiting for first VOBU" warning before, and most of the time a simple stream extraction and mplex solved it.

Package: dvdauthor
Version: 0.6.14-1+b1
Severity: normal



Then, I try to author a DVD out of that MPEG file, and I get:
 - first a pageful of "WARN: Skipping sector, waiting for first VOBU..."
 - then VOBUs are counted
 - and then:
     WARN: Partial sector read (4 bytes); discarding data.
     WARN: Cannot detect pts for VOBU if there is no audio or video
     WARN: Using SCR instead.
     dvdauthor: dvdvob.c:1321: FindVobus: Assertion `p>=s->vi[i-1].sectpts[1]' 
failed.
     Aborted






Cheers,

Nicolas

I've been trying to burn a DVD out of a DVB stream, without recoding the video. The DVB stream was recorded with vdr (as MPEG TS), and I used ffmpeg (-target dvd -vcodec copy) tu rewrap it as a DVD-compliant MPEG PS. Recoding the video stream (running ffmpeg without the "-vcodec copy" option) solves the problem, but I'm not fond of recoding since it degrades the quality (and in this case, in leads to a larger file). Hence, I guess my non-recoded stream is somewhat not compliant enough. But the I find the error message very uninformative... ii libjpeg62 6b-13 The Independent JPEG Group's JPEG ii liblcms1 1.15-1 Color management library ------------------------------------------------------------------------
