RE: [LIB] videos on 110CT
Date: Wed, 14 Nov 2007 09:33:28 +0100 From: "Avi Cohen Stuart" <[EMAIL PROTECTED]> Subject: RE: [LIB] videos on 110CT John, It is a bit more complex :-) There are a few parts that need to work together. - First there is a kernel driver for the margi which is a module that relies on the dvb framework. This is also with the original margi driver found at linuxtv.org. I adapted that driver first to work again on 2.4 and later on 2.6 with the help of someone else. The current version that I have works with 2.6.21.5 on a gentoo installed libretto. - The second part is the in the PCMCIA driver. In order to enable the ZV to work, a small adaption in the topic driver is needed (actually delete a few lines) - The third part is the enabling of the ZV port in the opl3sa2 driver. Also add one line there. - The fourth part which took considerably a lot work is to get the ZV to work on the Neomagic. I based my work on what Shigehiro Nomura did to get Xv working on the Neomagic. The Xv(3) library allows to work with overlays. I did a lot of reverse engineering using IDA Pro on the windows neo20xx.dll which does handle the Overlay stuff for Direct X. And I adapted the Neomagic X server driver. - The fifth part is the program which connects all this stuff together. Also based on previous work I changed the program which uses libdvdread, libdvdcss and libdvdnav to handle the dvd stuff, including navigation. Somewhere in the code it does of course a write() call to the driver which sends the dvd stream thru dvb to the margi driver which sends it into the hardware and sends the frames + sound via the ZV bus (without CPU intervention) into the Neomagic and the Yahama 715 chips. And it almost works like a charm! And the last 5 years I had a lot of fun with understanding how the DVD works, learned how to use IDA Pro (www.datarescue.com), learned how to kernel debug under windows with windbg, asked and got the sources for the Margi DVD-to-Go WDM (and MCI) driver and DVDPlay program which helped a lot btw, learned a great deal (again) about linux 2.4 and 2.6 device driver writing and how to use kgdb to debug the linux kernel using a Vmware system as my debugging host and the libretto as a target, bored my collegues endlessly about the above... Avi. N.B. I have to find time to dump this stuff on a web site once... in an orderly fashion... > -Original Message- > From: John [mailto:[EMAIL PROTECTED] > Sent: Wednesday, 14 November, 2007 1:47 > To: Libretto > Subject: RE: [LIB] videos on 110CT > > Date: Tue, 13 Nov 2007 16:46:36 -0800 (PST) > From: John <[EMAIL PROTECTED]> > Subject: RE: [LIB] videos on 110CT > > how does a dvd decoder like that work?

Date: Tue, 13 Nov 2007 20:24:14 +0100 From: "Avi Cohen Stuart" <[EMAIL PROTECTED]> Subject: RE: [LIB] videos on 110CT Hi, You don't need a ZV port for the margi dvd-to-go as you can send the video/audio out via the dongle. That does work for windows as well. I don't know if the 50/70ct is fast enough to feed the dvd-stream-hungry HW decoder. The ZV works great btw with good sound and a *very* sharp picture on the libretto :-) What options are you missing in the margi player? Note that the options might be limited because the DVD HW decoder chip (L64020) doesn't maybe handle all the options you would like to have.

Date: Tue, 13 Nov 2007 19:07:26 +0100 From: Anders Nordin <[EMAIL PROTECTED]> Subject: RE: [LIB] videos on 110CT I read on the Margi homepage once that the Linux(?) driver did not need a ZV-port (Zoomed Video port). Does that mean that it would be possible to hack a Windows driver to make the Dvd-To-Go card work on a non ZV-port laptop, like the Libretto 50/70ct? It would probably not work as great as with a ZV-port, but perhaps good enough? Also, does anybody know of a video player, besides Margi's own, that can use the dvd-to-go hardware?
