Ubuntu Multimedia :: Use USB Tape Converter But No /dev/video0 ?
Jul 7, 2011
I have a 'Gadget Geek VHS to DVD maker' USB device that takes analogue video in (composite) and plugs into the computer via USB.
Here is the output of lsuss (it's the eMPIA one):
Code:
Now this is essentially as far as I get, DBUS just says the following when I plug it in:
Code:
What I want to be able to do is open the (theoretical) output stream it produces in vlc and record it from there. Then I run into my next issue. There is no video* folder or link or file in my /dev directory and I can't stream video directly from the appropriate 'special file' inside /dev/bus/usb/00*/00*
I downloaded camE and camorama in hope of controling my webcam's framerate for skype because right now it's 24-30 which gives me dark video. But if I lower the frame rate to something like 10, the video magically brightens. camE doesn't do anything..like it turns on my webcam and does some ftp..fails..turns of my webcam ..back to normal. Camorama can't connect to my webcame. Cheese, guvideo are successfully able to conect to my webcam and play around with it.What I want to do is edit my /dev/video0 or some file from where I can fix the framerate for skype.
Although my webcam is identified. I cant get my webcam to work. gstreamer-properties complains - Video for Linux 2 (v4l2): Cannot identify device '/dev/video0' when testing. I have installed packages suggested by sticky.
I have a TV Card and a webcam connected to my computer. I've noticed that after a restart the TV Card capture device is /dev/video1 (while other times it's /dev/video0). When the device changes I have to update my tvtime.xml, which is a hassle.How can I force the capture device to be /dev/video0 and the webcam to /dev/video1?
Seemingly at random when I reboot my PC which I do every now and then, when I get it back up and running it will sometimes have switched my video card from using /dev/video1 to /dev/video0 or vice versa. It's not a huge deal but it is slightly annoying and I would like to understand why it does it and how I can stop it from flip flopping.
Not sure what you need to know in order to answer but I use 9.10, gnome 2.28.1, the video card is a Hauppauge 150 PVR something.
I have a usb webcam (off brand). When installed, /dev/video0 is properly created and I can access the webcam through cheese as a regular user.
Code: crw-rw----+ 1 root video 81, 0 2010-12-31 16:00 /dev/video0
The regular user is already a member of the video group, and I have checked all permissions under System->Admin->User/Groups->Advanced.
However, when as this regular user, I go to a website that tries to access my webcam via flash (ie, chatroulette or omegle), it does not detect the cam. (Firefox 3.6.13 with Flash 10)
I've already set the LD_PRELOAD as suggested elsewhere.
HOWEVER, if I LD_PRELOAD and run Firefox as root, all works fine and the flash plugin sees the webcam.
I have 3 old video capture cards which I would like to use for CCTV. Each card supports 1 camera. So I would like to have 3 cameras setup in the end and monitor them with zoneminder. When each card is plugged in on it's own, it works fine. Video comes through clearly with xawtv and zoneminder. However as soon as I plug in a 2nd card (with or without a camera connected) the output in xawtv and zoneminder goes haywire. It looks like the 2nd card takes over the first card, resulting in majority of the picture coming from the 2nd card, and some (if any) from the 1st card. When viewing either of the two cards /dev/video0 or /dev/video1 in xawtv the output is identical. I've tried this on a fresh 10.04 Ubuntu install, and on an older MythTV debian computer, the same results. Here are lspci -vv outputs with 2 combinations of cards (same fuzzy output):

My thoughts are because the capture cards are cheap (similar to winmodems), the problem may be in the software kernel modules not allowing room for other similar capture cards to run at the same time. Can anyone suggest me in the right direction? Do I need to setup some sort of memory allocation for each card manually? Something in the BIOS? An extra option when the card modules are loaded?
I am looking at getting a DLT drive for my network; however, I have never used the tar command with a tape drive. What happens if the data is larger then 1 tape? Does the tar application automatically span tapes or do I need to use switches so it spans multipule tapes? Right now my Full backup will take 2 or 3 tapes.
I have been using an LTO-5 Ultrium-3000 tape drive connected to an ATTO HBA without problem. I can control the tape drive using "mt -f /dev/nst0" and have been able to make successful backups using cpio, tar, and dump/restore. I followed some instructions on the web about how to install the HPE Library and Tape Tools application (version 4.21) which relies on conversion of a rpm to a deb file. The software seems to have been installed correctly and runs. However the hardware scan function does not recognize my tape drive. The following is suggested in the user manual if the tape device is not recognized by the software under Linux:
1. Login as root. 2. Edit the following file: vi /etc/modules.conf 3. Add the following line as appropriate: add options scsi_mod max_scsi_luns=128 4. Reboot the computer.
The problem is I don't have an /etc/modules.conf and am not sure exactly which file would be equivalent? If this is even the correct solution.
My tape drive is controllable and functions well using "mt -f /dev/nst0 status" so it seems to be a matter of LT&T software to detect the tape drive.
At the risk of providing too much info here some, possibly relevant, output from lshw

I've downloaded a few suggested converters, but they don't seem t ohave the right combination..I have some .avi's (from my camera) and want to put them on my website (using Joomla AllVideo component) so they have to be converted to .flv or maybe .mov.
I'm looking for a way to capture pictures from videos. I understand there is a free program for Windows that does just that but I want to use Linux if I can.
I am trying to find a way to convert MS Mpeg4 files to a format that is playable on Totem or any of the media players for Ubuntu. I have tried many converters, even trying ones in Windows (I really didn't want to but thought I would give it a shot)
I have installed all the limited FFMPEG and x2.64 restricted and limited libraries. I have all the multiverse and universe repositories. I have tried WINFF, Avidemux, DeVeDe but to no avail and now I am tearing my hair out. Totem cannot find any plugins suitable.
I have a set of archival files from a previous machine that ran windows and one of Microsoft's proprietary photo packages. I have a set of files with the extension .mix and can find no program to convert them. I have tried the ABC program but it fails with floating point exceptions.
I have a training CD for my job,its an interactive disk with audio clips etc. I want to try extract the audio which is in the .AUD format. I have tried SoundConverter but it does not recognize the extension.Firstly am I correct in saying the audio is the .AUD extension,there is another file in the same folder with .DAT extension.
What are some good VGA to HDMI converters that work well with linux? Any suggestions? I don't know the resolution I'm working with just yet, but it appears to be a 42" hd lcd tv/monitor. I think there's a VGA port on the back, but I'd rather route the signal through HDMI for better resolution.
I am looking for some conversion software to convert mp3 files to a format that will play on a standard CD player .cda so that I can listen to audio files whilst in my car. Does anyone know of such a converter.
I was looking for a converter to use on common avi files and maybe some others and came across this thread. I followed it all the way to where it asks me to install ConvertIt by adding the repos and then running Synaptic. I found convertit and marked for install and clicked apply and got this error:
Code: convertit: Depends: gambas2-runtime (<2.1) but 2.13.1-1ubuntu1 is to be installed Depends: gambas2-gb-qt (<2.1) but 2.13.1-1ubuntu1 is to be installed
So i check synaptic for that and i had them installed already from the guide. So i marked them all for reinstall since i installed them in the terminal the first time. Reinstalled and i still get the same error.
Any idea whats wrong? Or is there a better movie converter thats easier? I just want to re encode the files so the will play on my 360.
I'm trying to convert some songs I have in the Format .WMA to .MP3 searching around I found the program soundconverter, then installed it, only when I try to convert some music gives me an error saying that lack the decoder Windows Media Audio 9 also researched how solve this problem but got no success, I installed a lot of codecs and solved nothing.
I'm a palm pre user and I'm running 10.04 64 bit and I was just wondering what is the best video converting program to use to get videos to play on my palm pre.
So I still have a windows partition for two reasons: 1) Steam I know you can run this on wine and I have tried that, but I can;t run valve games at max everything (including AA and Filtering) and I like my good graphics so there is not much I can do about that. The other reason is AVS Video Converter, I've fallen in love with it, it converts anything to anything quickly and flawlessly, but I want an alternative to it for Ubuntu, something that works flawlessly just like AVS, to refine my needs more, I use it to convert video for my PSP.
You may all know about Total Video Converter, Any Video Converter and such used in Windows, where you chose codecs, like i want to convert to mp4 for my phone.
But.. there's one specific thing I'm looking for that most don't seem to have. Cutting. I need for example, to cut from 24:00 to 30:00, that is the only part i want cut and converted to mp4 ready for my phone.
I search for a Video Transcoder (neither ''Arista'' nor ''Transmagedon'') which can Recode a Video with my OWN options (like width: 640 high: 360)! And i need also (and this is more important) an Video to Mp3 Converter ( not WinFF, because i get an Error: libmp3lame unknown ) which i can convert many FIles at the same time.
