Edit decision list file

Is there a way to save the Edit decision list into a file?

Mythfrontend can read that data out of the database, so there has never
been any need for that capability. If you want some custom file in a
3rd party format, you're going to have to go into the database
(recordedmarkup) and generate it yourself.

MythTV uses frame accurate markup, and was actually the basis of
comskip.exe, so that one would probably be the easiest to do. Anything
else, and you either have to parse the video file to get the framerate,
or fake it from the seekdata (recordedseek) framecount and file
duration, and use that to estimate timestamps.

mythcommflag --help

see, particularly, --getcutlist and --getskiplist . Transforming it for
<random 3rd-party program> is your responsibility.

Is there any raeson in a PAL world that

frame_number / 25 = seconds

would not be valid?

Cutlist to chapter-file which, when imported in an mkv gets you what you
are after, as far as I can see.

mythcommflag --getcutlist -f $nameoffile | python -c "import sys,re;
cutlist=[re.split('\D+',l)[2:-1] for l in sys.stdin.readlines() if
l.startswith('Cutlist:')][0]; cl=[(i+1,.04*int(l)) for i,l in
enumerate(cutlist)];
cl=['CHAPTER%02d=%02d:%02d:%06.3f\nCHAPTER%02dNAME=Chapter
%d'%(ii,int(i/3600),int((i%3600)/60),i%60,ii,ii) for ii,i in cl]; print
'\n'.join(cl)" > $workdir/chapters$nameoffile

I was not sure I understood the question. If the question would have
been "In PAL world 'frame_number / 25 = seconds', is that correct ? I
could have answered with a Yes.

yeah that may have been a less elliptical way of expressing it.

I was following up from another thread that seemed to express some
doubt as to the correctness of such a simple formula:

I record from DVB-S for over 3 years. All SD-stuff is 576i, so 25fps or
50 interlaced fields. I use mythcommflag --getcutlist and the
frame-numbers I get are correct for me, always have been.
Dutch/Belgium/English/French/German-stations all work well.
I use it with projectx/tsMuxeR and ffmpeg, the last 2 I have to multiply
the framenumbers by 0.04, which gives me the time in seconds.

yes of course once we get out of SD we aren't really distinguishing
PAL and NTSC are we :)
