I appled all of your patches in CVS and am testing them. Initial quick
review all looks very good. I finally got around to setting up my iMac
DV and getting Xv working to try them first hand. 

Does the Debian package build kino against libavcodec for ppc? One
change I made is to enable libavcodec for RGB decoding on NTSC (was PAL
only previously). There must have been an old bug in libavcodec. This
speeds up the rendering of the timeline and storyboard.

Great news. Thank you!

Yes. ffmeg/libavcodec was added to the main Debian archives recently, so
nowadays kino in Debian builds with libavcodec decoding by default,
though I wasn't able to test the impact of this change on ppc myself.
I'll have a look at the NTSC change in CVS.

Regards,

Daniel.

Re: Quick patch to fix 64bit processors and AVI

Augusto, where did you get the Kino source you are using? The lines you
fixed below do not appear anywhere in our sources. It appears as though
the distro applied a patch and did not submit it upstream.

We have new code in CVS HEAD that makes AVI handling much more safe
across endian and architecture. It was tested by Debian users for quite
some time. Feel free to give it a try and let us know if it works for
you.

Re: Quick patch to fix 64bit processors and AVI

Sorry, I did not notice your patch was reversed. 

You said you "checked" CVS today, Avi.h was changed April 1, but not
exactly the same as your patch. It has extensive changes to deal with
cross architecture issues. Entire structs are packed and not just
certain fields as in your patch. Did you actually compile and test it or
just visually scan it?

DAzzle Digital Video Creator 120

Hi all,
   I'm new to this list but I think not totally new to 1394 or a few
of the folks here. Hi all.

   My son got a new video capture device based on his needs and not
based on what would run on his Linux box - the Dazzle DVC120. It runs
fine on my XP laptop but now I'm stuck with him editing his movies in
the studio instead of in his bedroom. Help me get him off my XP/Gentoo
laptop and back to his FC machine.

   While I know the history of Kino was 1394 based I though I'd
subscribe here and see what the consensus was about the following:

1) Does anyone know of info about the DVC120 running under Linux? I've
found only one thread about this and it didn't come to any
conclusions. I've written the original poster but haven't heard back
as of yet. (Only 24 hours)

2) Does Kino support non-1394 video sources for recording? The Dazzle
is USB-based. If so can you point me toward generic setup
instructions.

   I'm currently scrounging around for info on what chipset might be
in this beast and trying to build some video4linux support on the
hopes that maybe my 2.6.9 type kernel will just recognize it.

   Thanks in advance and hi again to all the old 1394 folks.

Cheers,
Mark

I saw your post to a gentoo user ml via a bloglines search feed on
"Kino," but my reply was rejected because I am not subscribed. :-)

No, Kino is strictly DV/1394 for capture and strictly DV for editing. I

Yeah, that seems to be the story.

I have add some luck converting with mencoder or transcode (can't
remember) a video to raw DV and then editing it under Kino.
Unfortunately, I was never able to have the sound, only the video. I
have tried to specify as close sound parameters as possible to what is
produced with dvgrab, but failed. However, there is no reason it
should not be possible, right? But I never went down to the
sourcecode.

I don't know which output format uses this Dazzle thingy, but...
I had once to convert an MJPEG stream coming from xawtv and finally
found that ffmpeg did the trick (fine piece of software, btw). Wrote 
a one-liner like this one :

ffmpeg -i $1 -r pal -ar 48000 -ac 2 -s 720x576 $1.dv

where $1 is obviously a filename given on the command line.

Hope this helps (a little bit),

It is actually quite easy to produce compatible DV using ffmpeg 0.4.8+
and specifying an output file with the "dv" extension. In difficult
cases, where the source can not be read by ffmpeg, I have used mencoder
to produce an intermediate (ljpeg avi) that ffmpeg can read. 

Unfortunatley, mencoder does not produce DV AVI output that Kino can
reliably read, or I just have not yet learned how (need to coerce audio
frame size to be the same duration as a single video frame). transcode
in the hands of an experienced user can produce DV readable by Kino, but
it requires one to be quite explicit with its options, which is why I
say for experienced user. gstreamer has pretty good support for DV, but
is much more complicated and little more capable on the input side than
ffmpeg.
