Dear Sven,
thank you very much for your detailed answer. Good to hear, what stand behind
dvbcut. I just asked about synchronization because I heard of other programs
that
are not got in that. Now I know, that everything is handled correctly.
In the meantime I tried dvbcut myself. Handling is much easier and faster than
projectx. The idea of having two sliders one with linear and one with a
non-linear scaling is very good and really helps editing. Also the option to
hear the audio some seconds back and forth is helpful. So I could very fast find
the points to cut at.
But when I tried to process the video the program crashed without any hints.
Unfortunately
I have erased the file so I cant reproduce this.
In a second try I was again able to set all the cutpoints. This is what the
*.dvbcut looked like:
<!DOCTYPE dvbcut>
<dvbcut idxfile="/home/jba/video/dvb/KOPFUEBR INDIE NACHT.rec.idx"
mpgfile="/home/jba/video/dvb
/KOPFUEBR INDIE NACHT.rec" >
<start picture="8380" />
<stop picture="59004" />
<start picture="70543" />
<stop picture="114363" />
<start picture="126205" />
<stop picture="190620" />
</dvbcut>
Seems ok to me. When producing the program stream, I got the following messages:

The resulting mpg was ok in the begining, but the last part was missing (I
suppose from picture 126205).
I still have all the files so if needed I could help in debugging.
Besides, there are some other things that might be improved, but they are not
that important:
- I think, one time mplayer crashed and video/audio were not played any more. I
had to stop dvbcut and kill the mplayer process. After restarting dvbcut
everything was ok.
- Aspect ratio was wrong in mplayer. I am not sure if this is maybe an mplayer
problem.
- I have a topfield TF-5000PVR where the ts-streams have the extension .rec.
This extension should also be in the 'open file' dialog.
- When saving dvpcut-files and program streams the program should by default
propose
'foo.dvbcut' and 'foo.mpg' when the original file was named 'foo.rec'
- Sometimes (very seldom) I have movies from dvb that are to large for a dvd5.
In this case I use 'tcrequant' from transcode to reduce the size of the mpeg2
video (.mpv) after demuxing and cutting in projectx. After that I would
multiplex the result with mplex (mjpegtools). How can I do the same with dvbcut?
Do I need to produce a complete mpg (audio and video) with dvbcut, then demux
it, tcrequant the video, and then multiplex again? Maybe it would be good to
have an option in dvbcut to output video and audio in separate files without
multiplexing them, to directly requant the video.
- In my normal procedure to go from a ts-stream (.rec from topfield pvr) to a
dvd I use mplex to multiplex audio and video. From the mplex manpage:
FUNCTION LETTERS
-f|--format format_code
This command allows one of a number of convenient preset output
......
8 - DVD (with NAV sectors). Don't get too excited. This is
really a very minimal mux format. It includes empty versions
of the
peculiar VOBU start sectors DVD VOB's include. This is
enough to
persuade some hardware players to play the stream but is a long
way from
full DVD authoring.
9 - DVD. As above but without the empty VOBU sectors.
As I use dvdauthor afterwards I use the format '8' (I think dvdauthor would not
work with '7', but I am not sure). What kind of format does dvbcut use? Will it
work with dvdauthor?
Regards,
Juergen
