Daneil,
Thank you very, very much. This is what I was hoping to find.
Now that I know what I'm looking for, I can do research on all of this
and hopefully it will make more sense, especially since you've got it
working.
I'm sure I'll run into problems, but at least they will be on a
different road than the one that I've been on for the last couple of months.

The g-400 -TV card has only graphics support. There is no linux capture
or firewire support for this card AKIK

Daniel,
Thank you so much for taking the time to answer my questions and trying
to help me. As sometimes happens, you've created even more questions and
concerns which I hope you or someone can address.
1. You mention that in your opinion, my 800Mhz machine may be marginal
as far as speed is concerned. I know Macs have been using 400 to 600 Mhz
processor speeds and capturing video without problems for years. I have
been using the Matrox system under Windows 98 for years without a single
frame dropped. I'm not arguing with you, but I find it hard to believe
that Linux would not be able to handle raw DV capture without any
problems and with an optinized kernal, be able to handle analog video
capture without problems. Any additional resources that you can point me
to on this subject would be appreciated. I've got fast hard disks, which
was always the bottleneck.
I'm spoiled and usually working at 640x480.
2. You mention that I would need lots of small parts, without going into
the details of what these parts are. From what you're saying, it sounds
like in order for me to be able to drive someplace, I must go out and
find all the parts in order to build a car to drive it someplace. No one
has a car already made for me to use. I really don't want to have to do
that. I simply want to do video editing on my pc. I hate Windoze and
switched to Linux, thinking that it would be better to do video editing
on, since it's more powerful.
kino (dv)
cinelerra (dv + analogue)
3. You then go on to tell me to try a couple of different programs that
will perform like what I'm used to under Windose. If these programs work
well, then don't I just need a capture card and driver to capture the
video and put it on my hard disk? To me, this sounds like you almost
solved all my problems.
yes
4. I've been on all the sites that you mention many times, trying to
learn about all of this. What I'm really looking for is someone that
does what I'm trying to do and to tell me exactly how they did it and
what they use. I don't think I'm interested the the MJPEGTOOLS because I
will be handling everything in DV, no MPEG whatsoever.
mjpegtools and avifile is required for kino/dvgrab
made easy here:
http://kino.schirmacher.de/redhat/8.0/en/i386/RPMS.kinorpms/
But, I'm not the
expert and I'm open for why I might need these tools. Reading the
MJPEGTOOLS site, it says that it uses xawtv for the capture of video. On
the xawtv site, it says that it's used for watching tv.
Xawtv is a viewing and capture program
What program do
I need to capture raw DV at 25mbps? What program do I need to capture
analog video to disk? I sure as heck can't seem to figure it out. Where
does it tell you this kind of stuff?
kino
5. I have read the entire Mandrake site carefully and I don't see what
that has to offer over my Redhat7.3. I've spent 4 months installing
programs and getting my system just the way I want it. I can update my
kernel to that version if that is what will make the difference. I can
also recompile my kernel with whatever I need in it to make it work. I
understand the importance of being able to update the kernel, and not
too concerned about doing it. I 'seem' to have almost everything that
Mandrake 9.1 offers already on my system. Is there specifics that make
Mandrake 9.1 better suited to what I'm trying to do? And if it's kernel
related, can't I simply update?
Then recompile your kernel with the relevant SVN (2.4) from linux1394
as anything below 2.4.18 is obsolete, and problematic. Be sure to
recompile with the code maturity option yes. (2nd selection in xconfig)
I'm sort of an OS junkie and like to optimise for Multimedia, realtime
apps. Mandrake instalation and hardware detection is trully flawless.
Red Had has for liscensing and legal reasons excluded any support for
mpeg, mp3, dvd support as of rh8.0. Also for multimedia applications on
Red Hat dma is by default off. (drive optimization) to turn it on
hdparm -d1 /dev/hda I think your going to be frustrated by tuning rh 7.3
to your needs. Things have come a long way in a short time.
6. Do you do DV and analog video capture and editing on your system? If
you do, I would sure love it if you could tell me what products you are
using. You did mention that you are using Avermedia capture cards. Do
you use more than one? Also, which model do you use. There seems to be a
bunch. And what driver(s) are you using. etc. etc. Specifics Please! I
beg you.
Hardware:
1.8 g celeron, 512mb VectorLinx (slackware made easy)
2 AverMedia TVphone capture cards (cheap 40.00 usd)
The chpsets on these are BT878 and work. Heres a good hardware list:
http://www.exploits.org/v4l/
1 Nvidia GForce4 128mb ram tv out AGP (cheap 50.00 usd)
1 ohci pci 3port firewire card (cheapest still 29.00 usd)
Packages required for firewire support (see linux1394 faq)
Libraw1394
libavc1394
dc1394
gscanbus (gui to verify 1394 subsystem)
You may find these tutorials helpfull for getting started..

For NLE and Capture I use Cinelerra, with 2 renderfarm nodes. I dont do
that much dv but dvcapture works great.
I capture and edit in 16bit yuva .mov and use mjpegtools to encode the
edited product to mpeg vcd 1 or 2 format. I use the CVS version of Linux
Video Studio as a graphical front end for encoding. You may want to look
at that as well.
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/mjpeg/studio/
For 3d graphics and animation I use Blender
http://www.blender.org
7. Maybe I didn't quite explain it clearly, but I was asking about using
my existing Matrox hardware, which also includes a DV and analog capture
card tied into the G400 video card. I know the video display works great
since I'm using it right now. I don't know how to make the other Matrox
hardware work as it's meant to.
Alas see top of message.
Daniel, again, thanks for your past help and (hopefully) future help.
There are no problems, only solutions.
regards,
Daniel Jircik
