Re: [Cooker] Re: Re: Mandrake for a PVR (was Re: Mandrake and business.)
Well, AFAIK Freevo uses SDL and can display on FB. I am just working on that right now. I am finding I have to hack SDL to display on the G400's CRTC2 using it's TV-Out mode. Note that this is NOT displaying to /dev/fb1 with all kinds of matroxset voodoo. Doing it using the CRTC2 properly gives a properly aspected, overscanned image, just like watching real TV. No black borders and dicking around with framebuffer timings. See the recent directfb-dev archives for more details. Is it based on this? http://www.sci.fi/~syrjala/directfb/readme.txt I'm looking into the latest G400 / G450 FB stuff (from ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/ ) Perhaps the kernel can be patched to use version 1.64 (1.62 now). Some other stuff I'm looking at: http://www.flashdance.cx/tv-out-mga-fb.html http://www3.sympatico.ca/dan.eriksen/matrox_tvout/ I have not looked at any of these, but if they address the second head as a second framebuffer (i.e. kernel config item CONFIG_FB_MATROX_MULTIHEAD=y) then it's the wrong approach. The approach that DirectFB is currently using is the exact same way that DVD playback works in Windows, which means the G400 displays a properly interlaced, overscanned image to the television. Question remains, can the two solutions co-exist? Otherwise I forsee problems when trying to merge it into the distro (if it ever comes that far). and will any fb application work with it or will they need to be patched (like mplayer http://www.sci.fi/~syrjala/directfb/mplayer/) It's to be able to program the PVR from a web browser. I like this feature -- it'll let me program it from work :-) But if you have the programs you want to watch scheduled by the name of the program and not by it's timeslot information (i.e. think old-world VCR BS) and your PVR does the timeslot programming for you based on when your programs are on (by downloading programming data), when would you need to program it from work? I suppose if you are at work and think all-of-a-sudden of a new program that you want to start watching, but is that a real-world situtiaton? Don't you usually make those decisions while sitting in front of the TV watching? Uh, no. :-) I see the promo's for nice programs a few days befor they air, and then forget to watch them (don't have a VCR of any kind at the moment). In any case, a web interface is not a bad idea, just very low on my priority list. :-) Stefan smime.p7s Description: S/MIME Cryptographic Signature

I have never really delved that deeply into it once I found out that it was useless here in North America, sadly. Not really. In fact only if you have a video-card that is capable to do this. Right. In fact you don't need a video-card at all, since the dvb-card is doing all the work. There are machines out there with 4 dvb-cards and a PII-300. The only thing you need is a lot of drive-space and maybe fast hardrives. Right. I am starting to drool. :-) The drawback is, if you want play games/ play back divx it must be encoded in realtime to mpeg to display it trough the dvb-card or u have to use a graphic-card seperatly. Right. I saw it. But for nvidia-cards have a look at nvtv. it does not rely on the commercial driver, and for my purposes the tv-out isn't bad. This is maybe because I had a look on the tv-out before buying the card. There are very different models out there. From VERY bad TV-out till quite well. Further the riva 128 , ati rage 128 and so on are known to work well. The next thing is that it is nearly impossible t get a matrox g200/g400 right now. Have you looked on e-bay? Last time I looked there were boatloads of them for sale. I was looking to get one to hook the Linux box in the bedroom up to the TV so I could watch stuff my PVR recorded there too. They will not be produced anymore and people who have them will not give it away ;) Well, no. You do have to give them some money for them. :-) As stated above. a PII-300 should be enough. Right. I really envy those that are in the DVB world. You get the broadcast in it's original MPEG2 format, not re-encoded in any way, and you can play it on low horsepower machines. On my duron 1,1Ghz playing a DVD trough dvb-card eats around 3% of cpu and with more than one card I'am able to record more then one stream the same time ( in my testings I tried to record 3 streams on one card on the same transponder and have had luck , it was possible) Cool! I should move to Europe. :-) The whole media/copyright BS thing in North America is going down the toilet anyway. North Americans are too uninformed about the laws that being passed over their heads, and don't really care anyway. When it's too late they will care. No need for it, if no divxplayback is needed. As stated above no graphic-card at all is needed Right. If I were in that situation, I would just resolve to transcode divx to mpeg2, offline (i.e. not expect to do it in real-time) anyway. b. -- Brian J.
