I've been looking at a number of places, but haven't managed to figure out what I need to know. I have a camera that only has analog NTSC output. I would like to get the frames into my Linux laptop. The frames are 8-bit deep grayscale and 320x240. I assume that they are getting expanded up into NTSC format or something; I'm ok with that; I don't need it to be very accurate. On my desktop box, I have a Hauppage WinTV PCI card that hands me the frames back via v4l. That works perfectly. I want to do the same on my laptop, only using USB rather than PCI for obvious reasons. (1394 would be fine too. But I want something cheap.) What devices are supported that would give me what I need? I scrounged around on the linuxtv wiki and various other places, but it seems like all of the USB sticks with analog inputs were doing fancy mpeg-2 compression, which kinda sucks for me: I'm not saving the frames anywhere, I'm processing them as they come in. So I'd rather not hav Steve Fink 2008-12-01T06:55:01 http://comments.gmane.org/gmane.comp.video.video4linux/41204 Hi Bill, Bill Pringlemeir wrote: The NTSC issue is a known problem. I tracked the error down to a commit Mauro had made (IIRC, back in April) which ended up causing a regression on some boards (e.g. KWorld ATSC 110/115). M.Krufky spun a quick patch (which works fine), but it cannot be applied to the main Hg sources as it too would break other things, and so some discussion would be needed to resolve the underlying problem. I was going to bug Mauro about the issue, but never got around to it, and I don't know if Mike discussed this with Mauro at the recent Plummers conference. (I have cc'ed both in on the message). Several posters on AVS forums were complaining of this and I posted a link to Mike's patch and instructions (including a warning that it could break support with other cards). AFAIK, zero feedback was achieved from that, as posters were either too scared by the warning or couldn't follow the instructions, nor responded to further posts. Whatever. In any regard, Mike's patch, as I said, CityK 2008-12-01T02:09:45 http://comments.gmane.org/gmane.comp.video.video4linux/41203 Stuart, while I don't know for sure, I believe that information about the power cycling is now obsolete and the driver for the ATSC 120 is working. In any regard, such things are not related to the difficulties Bill is experiencing with his 110 card. I'll detail in the next message. -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request< at >redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list CityK 2008-12-01T01:40:54 http://comments.gmane.org/gmane.comp.video.video4linux/41191 This thread may be of some help for you: http://marc.info/?l=linux-dvb&m=122738471231266&w=2 -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request< at >redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list CityK 2008-11-30T18:16:32 http://comments.gmane.org/gmane.comp.video.video4linux/41190 I have a HVR-1800 that I am trying to capture Svideo and stereo from a SA4250 Cablebox. If I tune the cable box to a channel, and try and run: mplayer driver=v4l2:device=/dev/video0:input=2:normid=0 -vo -xv tv:// All I get is a scrambled screen that is mostly green, and no signal at all. If I try to run it a second or third time or more, the input changes to 0 and it will not listen to the mplayer command to select input=2 no matter what I try. Does anyone out there have this working and can point me in the right direction to get this working? I would really like to get .mpg output from the svideo and analog stereo from this card. Otherwise, does anyone know of a card that I could use, that would work better? -Mark -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request< at >redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list Mark Jenks 2008-11-30T17:37:10 http://comments.gmane.org/gmane.comp.video.video4linux/41176 I have been trying to get my 2 HVR-1800's to work with my time-warner cable box without much success at all. Good thing I bought 2 of these, since they are exactly what I needed, and can't use them at all except OTA, since there are lots of problem with the analog input of these. I am looking for a good analog capture card that can get S-video and maybe audio from my TW box, so that I can use them in Mythtv. Does anyone have any suggestions on what cards have analog S-video support?

All earlier comments have been incorporated into this patch. I also made a new change: the mutex has been replaced by a spinlock and I no longer lock when walking the list of subdevs. So the assumption is that subdevs only added during initialization of the device and removed during the destruction of the device, and not in between. I cannot think of any reason why this you would want to do this, but should this ever happen then the list should be replaced by a klist. I consider this overkill, esp. since walking the subdev list should be as fast as possible.

Trilok Soni 2008-11-29T07:12:51 http://comments.gmane.org/gmane.comp.video.video4linux/41129 Hello, I'm testing at the moment the capture interface with the soc-camera and mt9m001 driver. I fixed all I2C routines to test without any connected camera like mt9m001, because we want to use another camera hardware as mt9m001. To read out the capture buffer I use the example project capture.c from V4L2-API with mmap(). The ioctl (fd, VIDIOC_REQBUFS, &req) at the beginning of initialization fails. I have debuged the most important parts of the driver (pxa_camera, soc_camera and mt9m001) but I can't find the mistake. Any Idea? Here is a short log, which functions were called: [< at >Linux /opt]#./capture -m soc_camera_open() pxa_camera_add_device() !!! camera 0-0: PXA Camera driver attached to camera 0 pxa_camera_activate() !!! mt9m001_init() ! pxa_camera_add_device() ret !!! pxa_camera_init_videobuf() !!! soc_camera_querycap() soc_camera_querycap() ret 0 soc_camera_cropcap() soc_camera_s_crop() mt9m001_set_fmt_cap() ! mt9m001_set_fmt_cap() ! ret 0 soc_camera_s_crop() ret 0 soc_camera_s_fmt_vid_cap() soc Maik Steuer 2008-11-28T14:58:44 http://comments.gmane.org/gmane.comp.video.video4linux/41125 Hi there, I've got one of these cards but I'm having trouble getting it to work. The problem is that it loads ok, but when I try to use it, it turns out that the tuner module has loaded the wrong tuner type. Instead of using tuner type 1, a PAL-I tuner which mine is, it selects a PAL-BG tuner. Now I've tried using type=1 in the modprobe line but it turns out that, that is no longer supported.

I'd like to turn on the IR LED's on the webcam for nighttime capture and it looks like the driver doesn't have that capability. Any advice on how to find out how to control the LED's? In addition to Linux, I have a windows machine with the capture software that came with the webcam that turns on the LED's during capture. Would it be difficult to capture and interpret USB traffic on the windows machine?
