theora - Feb 2008 - Misc: handycam raw to ogg / DVD to ogg

Hi,

I have two questions

1) How can I convert a raw miniDV file to ogg? I have made a
continuation to the conference I organised two years ago on
gravitational waves Astrophysics and Relativity and I have a lot of
miniDVs to be converted to ogg. I think I have seen the information
before but, after looking for some one hour, I have given up. And, by
the way, do you know how to dowload the file from the tape to the
computer avoiding kino? I find it too heavy. Something ? la command
line would be perfect (i have something like 20 tapes)

2) How do I convert a DVD to ogg format in the most efficient way?
Right now I am doing

mencoder dvd://1 -oac copy -ovc copy -alang es -slang es -o ~/DVD.avi

ffmpeg2theora --optimize -S 0 -K 500 ~/DVD.avi

Is there a way to avoid the avi step? (the alang and slang is to
choose the Spanish version of the DVD)

Thanks!

I believe ffmpeg2theora has a switch to encode from DV.

One of those should be able to do it, but I recommend you not keep
hammering that nail and try Thoggen instead.  It's a software (with a
GUI!) for ripping DVD to Theora.  The only thing bad you can point at
it is that it doesn't add the Skeleton track nor does it use the .ogv
file extension, which are all recent developments.  Next version
should probably add those things.

You could also use Ogmrip to create a vorbis+theora+mkv file. That way 
you get the benefits of vorbis/theora (being patent free), aswell as 
the benefits of the matroska container (multiple audio tracks, subtitle 
tracks...). Matroska is of course a free format as well.

Note that only vlc-svn and recent versions of mplayer are able to play 
these files (xine-svn maybe able to aswell).

Ogmrip uses the encoder_example I think...

I personally have little against Matroska, but the benefits you
mention are now also possible in Ogg through the extension called
Skeleton, which we are asking all implementers out there to support
it.

Please help in this process by submitting bug reports to all
applications that deal with Theora + Vorbis, but which have no support
for Skeleton yet.
