I have acquired a Canopus ACEDVio video capture card and can not get it to work.

View 1 Replies View RelatedI upgraded fro Jaunty to Karmic and then to Lucid and my TV card has stopped working. I had been informed that this was a result of the splitting of the linux-firmware into two separate packages, but having installed the linux-firmware-nonfree package the problem persists. The card is a Hauppauge WinTV PCI and although it is properly recognised by commands like lsmod, lspci and in the sound card settings, I can't tune in a single channel. It worked out of the box in Jaunty. Is there anything else that needs to be done to get the nonfree firmware working properly?
View 3 Replies View RelatedI'd be grateful for any suggestions to get a second TV/Monitor to work in addition to the desktop monitor for a PC which runs Lenny. The first monitor is a small TFTLCD 15". Works perfectly with a GEForce FX 5200 nvidia graphic card and uses the 173.14.09 driver. Having obtained an SVGA cable, I connected the card to a rather larger 32" LCD Panasonic TX-L32S10B TV to enable some armchair viewing of internet etc for my parents. The Panasonic TV or monitor shows all the boot messages but the graphical server fails to start. I know that both screens work, either alternatively or simultaneously, having tested with a Puppy live CD.
However, running
nvidia-xconfig --twinview results in an incorrect screen resolution for the 15" TFT Monitor; Gnome Screen Resolution Preferences gives a rather surprising fixed setting of 2048x786/50Hz when the maximum should be 1024x768. The resulting xorg.conf file is:
cat /etc/X11/xorg.conf

I have a PCI graphics card, Nvidia Geforce FX 5500, but can't get it to work. I have 10.04 installed on a Dell Dimension 3000, P4, 1Gb RAM, integrated graphics. I installed 10.04 without the card in the machine, then shut down and plugged the card in and booted it up again (BIOS setting is 'onboard' for integrated graphics, 8Mb; only other option is 'auto'). Checking the hardware drivers I can see the recommended Nvidia drivers (v173, not yet activated) and lspci gives me the integrated as well as the Nvidia listing:
01:02.0 VGA compatible controller: Nvidia Corporation NV34 [GeForce FX 5500] (rev a1)
00:02.0 VGA compatible controller: Intel Corporation 8286G Integrated Graphics Controller (rev 02)
So far so good, but that's where it ends. Changing the BIOS setting to 'auto' turns the screen off on reboot, both for the monitor connected to the VGA port of the Nvidia card and for the monitor connected to the VGA port of the motherboard. I have to shutdown, take the card out and set the BIOS back to 'onboard' to be able to boot again (and shutdown, plug the card back in and boot up again to get back to where I was).
Activating the recommended hardware driver and rebooting (still with BIOS set to onboard) gives a blank screen (screen is still on and there may have been a flash of the purple screen with the ubuntu logo); nothing else happens no matter how long I wait. Rebooting doesn't help, it turns off the screen; same result for booting in recovery mode. I can get to the GRUB bootloader and when I replace 'quiet splash' with 'nomodeset' I manage to boot again with the monitor connected to the VGA port of the motherboard, but am not anywhere closer to getting my monitor working on the Nvidea card.
I've no idea what the heck is going on with my TV capture card, i went to the other posts about my Hauppauge Inc. HDPVR-1250 model 1196 but it all didn't work i have the ubuntu-restricted extras installed but mythtv is not picking up the card. i'm running ubuntu karmic.
View 9 Replies View RelatedI have been trying to put together a mythbox for myself. I installed Ubuntu 10.10 and the newest version of the Mythbox backend. My capture card that I am having issues with is a Hauppauge Wintv-HVR-1850 card, I followed the instructions on installation from linuxtv.org and did not get any errors. I tried to set up Mythtv and it didn't get a signal and couldn't find any channels. I would like to know if my card is even working so I tried using xawtv but still could not get a signal from my card.
how I can verify that my card is installed correctly?
I'm trying to setup Mythbuntu on a computer connected to a TV. I have bought an USB DVB-T Receiver, named WandTV. According to LinuxTV; WandTV, aka Shenzhen Forward Video EzTV859, is supported in the Linux kernel.
When I try to setup the mythTV backend I'm being asked of what card type I have. I guess the answer to that is "DVB DTV capture card (v3.x)", but no matter what I choose, it can't find any devices.
I'm pretty sure /dev/hidraw0 is the receiver, can I use that to setup the backend?
I previously had my bt878 capture card setup with Ubuntu 10.04 and it worked fine with Zoneminder. However, after having done a clean install of Ubuntu 10.04, the card causes Ubuntu to freeze whenever I attempt to view the image in a viewing program (happens in tvtime, Cheese and Zoneminder)I have added bttv and bt878 into /etc/modprobe.d/options like before, and have also added options bttv card=77 tuner=-1 into bttv.conf in the same directory (had to create bttv.conf)The freeze causes the whole computer to lock up, and nothing on the keyboard or mouse is responsive, and involes having to do a hard restart.The only difference I can see from before, is that I have installed all of the latest updates with Update Manager, so maybe a new update is causing these problems?Output of dmesg � grep bttv

Does anyone know an Ubuntu 10.10 compatible video capture card that has composite connections for video and audio (yellow, red and white)? It must be external and do its own processing so it doesn't use the computer's own CPU. I intend to capture a live stream and have the Ubuntu PC serve it to other computers. I may use VLC or MythTV. I have looked on various related sites but finding a compatible USB one which does its own decoding is hard to find.
View 2 Replies View RelatedI have an old video card, Nvidia XFX 7800GT, which is now beginning to fail and I need to upgrade. I am not huge a gamer but I do play/buy games on regular basis. Right now I'm playing Eternal Lands on the Linux side. Looking to spend $100-$150 on a new card.I have a Core2Duo Wolfdale 3.0, with 2ghz ram and run Lucid 32bit. Also run windows Vista64Ultimate on dual boot (rarely).
I would love to buy a new ATI 5770 or 5830, ATI budget cards seem to be much better for the buck over budget Nvidia cards, but I'm concerned with ATI drivers and long term with Ubuntu.On the Nvidia side I'm considering the GTS 250. The only advantage I can find is lower power consumption with Nvidia and Ubuntu has always preferred Nvidia over ATI, as far as working drivers go.As Far as Ubuntu and Lucid is concerned, which way is best, ATI or Nvidia? Has anything changed with ATI support, that could make theor cards more compatible now and in the future?
Many people are having trouble with the latest nvidia drivers. I think there might be a pattern and that might lead to a solution; even if that solution is "give up with that card you're using." So, here's the first:
7600GS PCI with 32 bit opensuse 11.3 and KDE 4.6
The sort of add on for Firefox 'download helper' now has a new screen capture thing, in case it won't download the video from a particular site. You click the red button and a purple boundary appears round the video frame. I assume this is the basic function of the thing; it then provides the geometry of the purple frame to the program you've given it to capture the video.
By default the program it uses is 'recordmydesktop'. I've tried using this but get sound from the laptop's internal microphone, not the video. Tried 'pavucontrol' to remedy this but it says (wrongly) that no program is recording, so can't put things right.
So tried using ffmpeg: [URL]
Assume the stuff in curly brackets is what download helper supplies. Sometimes works perfectly but with B.BC. i-player only get the top left hand corner of the video and it is stretched somewhat horizontally.
I'm trying to capture my desktop screen and audio , before I used xvidcap but after upgrading my system I can not use it and also recordmydesktop anymore these APPs hanged when I try to use them.Now I try to use recorditnow via ffmpeg recorder interface , it work properly in recording the desktop but it does not record the sound , so I tried to add below options to its command -f alsa -ac 2 -i hw:0,0 but it just record sound at the beginning and just for 1 second. Also when I try to capture my desktop with ffmpeg directly from command line with below command I face with same problem!!! ffmpeg -f x11grab -s 1024X768 -r 30 -i :0.0 -f alsa -ac 2 -i hw:0,0 ~/out.mpg
View 9 Replies View RelatedI have just installed openSUSE 11.1 64 bit on my system. Subsequently registered to get an auto-update repo and auto-updated until no more updates were offered. Then I first tried YaST to install NVidia drivers from the NVidia repo (added their repo), but sax2 wouldn't recognize them. So I downloaded their 190. (beta) drivers, installed the kernel source code and gcc 4.3. Then I switched to a console (Ctrl+Alt+F1), closed the x server, ran the driver install as described (gcc 4.3 is installed). Installer said that all is fine (I checked the log to be sure). So I ran sax2 -r -m 0=nvidia, but the driver still isn't recognized.
View 6 Replies View RelatedAfter installing nvidia drivers (sudo yum install kmod-nvidia), Fedora12 (kernel 2.6.31.12/5) fails to start. To be more exact, it show the 'loading screen', and then the screen gets all scrambled. Trying to switch the ttys doesn't work either (though I can boot in runlevel 3).
I know that there might be some conflicts with nouveu, but i followed the steps from 'Fedora Nvidia Driver Install Guide' (not allowed to post URLs), so I guess nouveu isn't exactly my problem(?).
Another puzzling thing about this, is that I can boot and use FC12 from VMware. No problems there. I also tried removing/reinstalling the kmod-nvidia (and everything else nvidia related), but the problem persists.
Specs: Intel core2duo t7300, nvidia 8600m gs, 2gb ram.
PS tried nvidia installer previously, and problem was the same, so I reinstalled FC12 at that time.
I'm trying to install Ubuntu (or Xubuntu) on a PC that has integrated on board video. After that I want to disable the onboard video and use an NVIDIA GeForce 8400GS video card.
I tried it before, and got a lot of resolution problems.
This is what I did:
- First, I put the card in the PCI slot and modified the bios to use it as the default video, and booted from the ubuntu CD. The installation did not go through as I got no screen output (I guess ubuntu did not recognize my video card).
- Second, I restarted and modified the BIOS so that the onboard video was the default. This worked when I booted from the CD and installed, I got screen output and all. I completed the installation and turned off the computer.
- Third, I installed the card on the PCI slot but did not change the BIOS, booted and used the onboard video, downloaded the NVIDIA driver (190.53) from the NVIDIA website, installed it, and turned off the PC.
- Fourth, I modified the BIOS so that the NVIDIA video was the default, plugged the monitor to the NVIDIA VGA output, restarted, and got ubuntu working at a very low resolution of 640*320.
This is where I am stuck. I can't change the resolution to 1024*768 or 1366*768. I only get 640*320.
Is there any way to avoid all this and do a fresh installation of ubuntu 9.10 with the NVIDIA card already in and as default on the BIOS?
I am thinking the resolution problems started because I got video drivers mixed up with intel onboard during installation, then NVIDIA. I guess I should have removed the intel drivers first before installing NVIDIA drivers. If anyone agrees, how do I uninstall Intel video drivers?
If that is not the case, how do I configure the NVIDIA drivers to work properly?
My PC is an older IBM 8303 KKU at 2.26GHz, with 2GB RAM, 40GB HDD, and a 512MB NVIDIA GeForce 8400 GS
In Ubuntu 9.10, I was successfully able to use my Pinnacle Dazzle DVC 100 (a cheap USB analog video capture device). I use it for backing up old video that is stored on tapes, and it isn't working with my current install of Ubuntu 10.04. When I plug the device in, it should be detected and the em28xx module should be loaded. This fails and /var/log/messages has the following:

Since ffmpeg 6 is out for some time, when will Ubuntu Lucid afford such a new ffmpeg package from its repository?
