  1. Done it. by Synpax · · Score: 2

    I've been working on a similar project, but using a headless box. It has a TV tuner in it, and runs Linux 2.2.18, with the latest V4l drivers. The trick is, that an extremely clever person put this little program together vcr. This program lets you record any video4linux stream straight into any format supported by avifile to disk. Consequence? I now have a skeleton of a web interface that is based on tvguide, that I can select shows from, and have this program automatically record them, straight into low motion DivX, which is really good quality (arguably better than Tivo's MPEG-2) If there is interest, I'll complete and release the project. I can then watch the recorded show on any box on my network, or even the box connected to my TV. It'd probably be cooler to have a TV out card, and watch it right on my TV, and even have a TV interface, but let's walk before we run :)

      I've been doing the same thing, but with avifile's qtvidcap. I've tried various versions of vcr, and they all had problems. I think they crashed. Don't remember, but I put vcr into my "don't download again" basket. I found that I couldn't quite get divx quality in real-time, so I'm capturing in 100MB mjpeg (damn that licence, I must try different formats) chunks and converting to divx once the first 100MB is done. I'd be interested in that tvguide / web interface to recording thing - but only if it works in Australia...
      I'll be getting a Radeon soon though, so I suppose I'll be abandoning all this for Gatos.

    Anyone play around with hardware MPEG2 encoding? I like the Hauppauge WinTV-PVR (different than the regular WinTV), but it looks like this thing is Windows only :( I'd like to be able to capture and record stuff directly to MPEG2. Anyone know about any Linux drivers for this one? The regular WinTV works with video4linux, but this one apparently does not.

    I'm praying to god that this is a troll. If not, here's my response:

    The ability to copy digital video DOES NOT IMPLY PIRATING you CLOSE MINDED BAFOON! Macintoshes can do this already. Do you associate THEM with pirating?!?! What if you happen to have a digital video recorder or some such device and which to easily copy its contents to your harddrive?

    Copying digital video to your harddrive WILL NEVER BE ILLEGAL. Copying specially COPYPROTECTED digital video will be, probably. A humungous difference.

    Also, I'm not completely sure that seeing an OS as good for pirating will hurt your business with consumers. It may make companies more wary but I'd think it would actually attract users.

    Also, yes, linux CAN rip DVD's. Both legally and illegally. This is not wrong. If you want an impotent OS that can't do anything illegal even if you wanted to than go to Win98. You'll be too busy rebooting to notice how much it sucks though.

    No one here is "'Hacking' devices for illegal purposes", we are just hacking devices. Hacking is not wrong. This is not wrong. It COULD be used for things that are wrong. I could also beat you to death with one of my Neal Stephenson books, which sounds pretty good right now (probably the effect of playing all those video games ;-)), so maybe we should just outlaw books since they can be used for illegal purposes.

  7. Not with my old Matrox Rainbow Runner, it won't... by Bonker · · Score: 2

    Alas, alack... One of the only reasons keeping me from switching completely over to Linux running Gnome and Wine is the fact that my video capture device just doesn't cut the mustard under linux.

    It's not an appropriate card for gaming, but I have another card for that in the same machine. It even outperforms newer video capture devices in terms of quality and capture stability. Better yet, it works pefectly on a machine as slow as a P1 133. (A 3dfx 3500 TV card has problems with synchronization on anything slower than a p3 550)

    Unfortuneately, this problem is pretty standard across the board. Matrox is unwilling to support this card on newer OS's (Linux or Win2k) and Linux drivers just don't exist. Unfortuneately, I'm an artist and don't have anywhere near the coding skills necessary to craft my own. I doubt anyone else could because of this line I found in a Matrox email post: "Matrox has evaluated the required resources to produce a "black-box" for Linux to enable the use of the non-Matrox components. Unfortunately we concluded that many man months would be required and we cannot assign such resources to this project."

    Older, yet servicable hardware is getting more and more support on linux, but because of crap like this, it's still lacking in a big way.

  8. Re:Today is a sad day for Linux by jtdubs · · Score: 2

    This is the same debait in my mind as to why Napster was wrong but FreeNet was right. Napster was specifically designed to trade illegal MP3's regardless of the lies the creater spews out to cover his ass. Freenet was designed as a generic way of trading files. All files. Random files. There is nothing illegal about that.

    I find it absurd that a program that has no illegal intent, but COULD be used illegal could possibly be viewed negatively. You shouldn't have to limit your program to make it legal.

    Is fdisk illegal? I could use it to wipe out your harddrive. Or a companies harddrive. Just throw it on a bootdisk and go computer to computer rebooting off the disk and wiping harddrives. That would be illegal use of the software. Should fdisk have been designed to make those kinds of things impossible? I don't think so. What's the difference?

    Just what I need. Instructions on how to turn my $2000 Linux box into a $100 VCR.

    Well, I have a $100 VCR, about a year old. Current problems:

    • It's an analog device, so any noise in the signal (and I see a lot) gets amplified.
    • Quality degrades even further if I record at slow speed, which I need to do if I want to record more than 2 hours unattended.
    • It's not just an analog device, it's a complicated analog device with a lot of moving parts. At any given time, one or more of these things is worn out, misbehaving, or dirty. Currently the thingee that looks for the record-allowed tab is hung up, so I can only play back. Various other problems. In general, VCRs break suddenly and unpredictably.
    • As long as we're figuring costs, figure the repair bills and the inconvenience of taking the thing in. And the cost of replacing the whole thing when the repair bill (generally high) exceeds the value of the machine (which degrades very quickly).
    • Fast-forward and commercial skip, though improved over previous models, are still very tedious to use.
    • The VCR is not a very hackable box. Given a choice, most slashdotter prefer to hack their own systems, even if its slightly less cost-effective or convenient, no?
