Ubuntu Multimedia :: Can't Open Firewire Capture Device
Jan 22, 2011
I'm trying to view the output of a dv firewire capture device (advc-100) fullscreen through vlc. I've read of people being able to do this but a detailed explanation of how eludes me.
I'm running Ubuntu 10.10 and VLC 1.1.4
The error message I'm given after trying to open through 'media>open capture device>play' is;
Quote:
Your input can't be opened: VLC is unable to open the MRL 'v4l2:///dev/ffc1/'. Check the log for details.
(and I can't find the log)
I'm not even sure if I've got the device name right so I ran lspci from the command line which gave the following output (and I still can't work out what it is);
Quote:

I have been trying to get tvtime or any tv package to work with my Pinnacle PCTV HD usb but I have not had success. I have correctly installed every driver imaginable. So, here is what it what it comes down to: When I open tvtime it says "cannot open capture device /dev/video0" and the screen is blue. But my usb PCTV HD stick is NOT /dev/video0 so the question is how can I get tvtime to look for the usb tv tuner rather than video0?

I've made a lot of progress getting my easycap 2.0 usb capture device to work with ubuntu 10.10. I've got the picture up any everything works great. But about a minute into the stream it just freezes, I need to go into "playback" and either pause then play, or click "next", it then refreshes and works again for another minute or so. I'd believe it if someone says faulty hardware because the easycap is cheap, but I don't think that's the case. Additionally, is there any way to set VLC so that when I open it, it automatically opens with my video capture device (/dev/video0) so that I don't have to go into the options and change it every time?

I'm using FFADO on JACK in order to use my firewire device (M-Audio Profire 610) and I seem to have the opposite issue as others who have similar problems. Everything starts up fine, and I can record audio into Ardour using my inputs, but I can't get any output from any of my 8 line outs.
I've checked the connections using QjackCtl, and I tried to route audio from another program (Audacious) but I can't seem to pull audio out of the device (or the computer won't send my device audio?).

I need to capture from my webcam. It has a mic too.I can specify video input device as /dev/video0.I specified input audio device as /dev/dsp2 ( OSS device, corresponding to USB Webcam), Now VLC throws an error, "VLC is unable to open the MRL 'alsa:///dev/dsp2'. Check the log for details".Thinking it wants an alsa device, I specify device as /dev/snd/pcmC2D0c. (got it from kinfocenter and dolphin). Now again an error, "VLC is unable to open the MRL 'alsa:///dev/snd/pcmC2D0c'. Check the log for details.".I try with any device, the same error. I have added myself to audio device so that I can read/write to the mentioned devices.I see no way of switching VLC to use OSS. And I see no information (documentation on net) on it's expected device listing for audio.

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:
Code:
Sep 25 16:13:18 kernel: [1196215.111898] usb 2-2: new high speed USB device using ehci_hcd and address 20
Sep 25 16:13:18 kernel: [1196215.266097] usb 2-2: configuration #1 chosen from 1 choice

I have two sound devices, an internal audio device on my motherboard and an external USB devices, which came with my headset. After upgrading to 11.4, the microphone on my headset ceased to work with my softphone. As it turned out, the softphone used the standard input device, which was defined in the Phonon tab in the KDE System Settings. Unfortunately, when I put the USB Device on top of the default input stack, it doesn't stay there. When I apply the changes and leave the Phonon tab or even enable "Show advanced devices " the stack always resets to its initial order. I was unable to find any kind of config file where Phonon saves this settings.

I just setup a FireWire audio interface. Everything works fine, except for I need rw-rw-rw- permissions on /dev/fw0. I can always sudo chmod 666 /dev/fw0 just before setting the thing up, but then it will be gone on the next rebooting.The solution to modify /etc/udev/rules.d/020-permissions.rules (which is for Ubuntu Breezy) doesn't go well for Ubuntu 10.10 Maverick because there is no /etc/udev/rules.d directory.

I was trying to burn an .iso with K3b a little while ago, and had some problems. First of all, even though I chose 8x to burn my (16x) DVD, it switched to 11x or 12x around halfway through the burning process. There were also some ticking noises that I'm pretty sure were coming from the DVD writer, not terribly loud, but noticeable. This had never happened before. Finally, it got stuck at about 98% (but not frozen, as the time elapsed kept going), and did not finish burning--got an error message (and a bad disc): "cdrecord has no permission to open the device"
I inspected the disc and there was one dark spot (on the dye) about halfway through the disc, very thin and couple of millimeters long. (This was present only after burning). I'm using Ubuntu 10.04, K3b version 1.91.0, Lite-On DVDRW SHW-160P6S

Got a Ubuntu system. Have a device on my LAN that can send Syslog messages.
I would like to:
1. Capture these specific syslog messages.
2. Keep them separate from any other syslog activity on the Ubuntu system.
3. View these syslog messages later.

I want to capture DV-video through IEE1394 (FireWire) with Kino and Ubuntu 10.10. Seems I can't capture... When I plug in the camera there is no hot plug message (if there should be one? I've read it should...). The DV-out on the camera is enabled There is no option to enable/disable the port in my BIOS.
Some information:
Code:
a~# lspci | grep 1394
07:09.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 05)
Hope there are some command to check?

I bought a USB to firewire cable to use with a DV camera, but I don't know what to do now. Do I need to enable firewire drivers, or is there something else I should do? I know I should read the manual.

I have a Panasonic DVCPRO HD camera with a Firewire output. I'd like to take the video footage off of the camera and put it into my Ubuntu (Studio, 10.04) machine. Unfortunately, neither my Ubuntu machine nor the camera seem to recognize a connection with each other.
I've only used this camera like this with Mac OSX, in which I press a button a couple folders pop up with everything in them which I can then digitize in Final Cut Pro. I'd prefer being able to use my Ubuntu setup with Open Source Software to view and edit this footage.
how to get ubuntu and this camera to talk to each other and play nice?

I'm getting some jitter when capturing via RCA or S-Video from an em28xx device. Input type is PAL, other than that I haven't fiddled with mplayer or vlc's options (vlc only sees the RCA input, mplayer sees both)

I had originally planned on buying a USB 2.0 audio interface to use with my first home recording studio, but it sounds like Linux support is pretty horrible for these devices. On the other hand, the FFADO project seems to be very promising, so now I'm looking at getting a firewire interface. The only problem is that all I have on my laptop (sony vaio VGN-N365E) is a little 4-pin firewire port. If I'm not mistaken, those don't provide any power. Will this work with any interfaces (maybe one that has it's own external power adapter)? Or is there an adapter I can get to convert it to a full firewire port and add power?

I rebooted my server and out of nowhere the RAID5 array won't assemble. I've tried everything I could think of to reassemble the thing. I fear that the array is ruined, but I can't imagine how. Here are various bits of information: The simplest failure (with and without partition numbers, which have not been needed in the past):
Code:
richard@nas:~$ sudo mdadm --assemble --verbose /dev/md0 /dev/sd[bcd]
mdadm: looking for devices for /dev/md0
mdadm: cannot open device /dev/sdb: Device or resource busy

I'm a complete Linux newbie - only installed it yesterday, and have spent hours trying to get my M-Audio Firewire Solo sound card to work. I can hear nothing at all. I know nothing of Linux, but am willing to learn. While I learn though, it would be nice to listen to a little Hall & Oates. I've got to the stage where the error messages I'm receiving don't bring up any results on Google. Here's what things look like (watch out, big pic):
Those sample rate errors appear in the terminal when I start ffado-mixer. I'm running JACK with everything set as I think it's supposed to be, except that 'Realtime' is unchecked.If I start JACK running with 'Realtime' checked, it tries to launch and fails, saying "JACK is running in realtime mode, but you are not allowed to use realtime scheduling. After applying these changes, please re-login in order for them to take effect". I don't know what more it wants me to do - i've already added
@audio � rtprio 100
@audio - nice -10
@audio � memlock unlimited
to /etc/security/limits.conf, and selected the 2.6.31-11-rt kernel on GRUB bootup. I'm a member of 'audio' and 'disk' groups like'm supposed to be. Have I not got the connections right in JACK? Have I got some sample rate settings wrong somewhere?I'm not even bothered about low latency with the realtime kernel right now, I just want to hear some sound

I used to watch and record TV in Vista and Win7 with a SAA7134 capture card, and all worked fine. Using TVTime in Ubuntu 10.10 64bit (no upgrade but fresh install, everything up-to-date), I get picture but no sound. Instead I get this error message when running TVTime from the terminal: Can't open device /dev/mixer, mixer volume and mute unavailable.Using lspci in terminal lists the card as following:
Code:
02:01.0 Multimedia controller: Philips Semiconductors SAA7131/SAA7133/SAA7135 Video Broadcast Decoder (rev d1)
And dmesg outputs this:
Code:
[ 16.078404] saa7130/34: v4l2 driver version 0.2.16 loaded
[ 16.078458] alloc irq_desc for 17 on node -1
[ 16.078460] alloc kstat_irqs on node -1[code]....
Being rather new to Linux (oh great, another newbie ) I don't know what additional info you might need, but I'm more than happy to post everything neededd - provided you tell me how to get that info.

I have created several DVDs from my camcorder (sony handycam DCR-HC21 NTSC); however, the recordings are too long. I would like to capture smaller segments of these and load them online to share with family and friends.I would like to know what is the most recommended software for this task. I am running Ubuntu 9.10.I would have done this by using a firewire cable directly attached from the camcorder to my laptop, but my laptop has only USB ports. So I ended up creating DVDs using an stand alone Video Recordable DVD Drive.
