Ubuntu Multimedia :: 10.10 - Setting VLC To Open With Video Capture Device?
Dec 18, 2010
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 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'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);
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'm building a Linux system specifically for video capture in prep for yet another video games review site I want to attempt. She is running Debian Sid with Enlightenment as her desktop.This system actually has two different devices that should be able to do the capture from the Wii, PS2, XBox, and other systems that can connect to it. The first is the video card itself, an ATI Rage 128 Pro AGP 4X, which has TV (aka composite) in as well as what I am guessing is S-Video in (not positive on that since the port has significantly more than 4 pins unlike the S-Video ports on my AV switch). The other is an external ATI TV Wonder USB TVWonder, which has coax, composite, and S-Video inputs.
When I installed and ran XAWTV, it crashed with a complaint that there was no video grabber device found. When I did lsusb, I saw that there was no sign of the external USB capture device. lspci showed the video card, but no mention was made of its TV capture feature. However, I am not certain if there was supposed to be any separate entries for that.So anyway, before I start bogging you all down with what may or may not be too much system data, I first need to know, is this an exercise in futility with the hardware I have? Is video capture with Linux even possible with these, or should I start shopping for something else?
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)
video playback is like I have applied a blueish sepia filter over it. And this is just the playback from totem player or mplayer, and not the playback from ..... (and generally online streaming) - this works just fine. this messy video playback also appears when I use cheese to capture video with my webcam. Note that the preview picture of the video file on nautilus has the natural colours it should have.
at first when I installed the os this particular problem didn't exist, but it came up the time I decided to follow the "comprehensive multimedia guide". So now I have all the pros of following the guide, but this is a major con...
I'm making an attempt to install drivers for my easycap dc60 USB video capture device. Someone was good enough to make a driver project on sourceforge. Problem is I cannot get it compiled.
Code: Building make[1]: Entering directory `/home/jan-bart/Download/easycap_dc60.0.4/src' make -C /usr/src/linux-headers-`uname -r` M=/home/jan-bart/Download/easycap_dc60.0.4/src modules make: Entering an unknown directory make: *** /usr/src/linux-headers-2.6.31.8-0.1-desktop: No such file or directory.

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.
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.
How do I capture video from my JVC GR-DF470 MiniDV camera into 10.04 Lucid.PiViTi looks good for an editing app, and I've installed OpenShot as well, but neither have a way of capturing the video from a camera. I used Kino previously in 8.04 Hardy, but it was buggy at best in 9.10 Karmic; I've just installed it in 10.04, but capture keeps stopping after 2 or 3 seconds. I also tried kdenlive, but the audio capture has a lot of 'noise' that is louder than the voices on the tape, and once it finishes capturing video, it doesn't display a 'Save' dialogue as it is supposed to - so that wasn't very successful either.So what can I use to capture video from a MiniDV Camera via Firewire.
I am working in a script I have, to capture video with sound from my capture board, wich is a clone of the pico2000. This script was working in Ubuntu 9.10 untill I reformated my machine and instaled the Ubuntu 10.10, 64 bits. The machine is an AMD Athlon II, 2.6GHz with 3 GBytes of Ram. The former script was:
This is on Karmic Koala 9.10. The video displays fine via guvcview using a Logitech webcam. The trouble is the capturing of the video. With .AVI, I've tried different video formats (MPEG-4, flash, etc.) and none of them will play. The generated .avi file seems to grow with data, but the result is just unplayable -- it just hangs, thinking it's playing. Is there a troubleshooting page or something to figure out what the problem I'm having with guvcviewer is?
I'm using natty. is there any way to get a Pinnacle DVC 101 to capture video from composite source on Ubuntu Natty? it seems that when new releases break functionality they often are never fixed.
I'm also unaware of a simple GUI application to use in order to capture the video. It would need start and stop features.
As a TOTAL noob to Linux setting up my ATI All-In-Wonder 2006 AGP card with GATOS to allow me to transfer old video tapes to my computer (for further editing to DVD). I have Ubuntu 9.10 loaded and the relevant link for the GATOS stuff is:[URL]..
I use Ubuntu 10.04 in my HP 6530s notebook(2.0 C2duo1GB RAM, 512MB video). Recently i downloaded GyachE v1.1.48 for yahoo video chat. after installing GyachE when i started webcam its showing errors: Fatal: Video format not supported by Grab device.
Anybody had any success in getting ffmpeg to work as advertised with video capture from a webcam? I really want to convert the webcam output to VP8 or H264, but apparently ffmpeg can't even capture the webcam with a video4linux device.
I wanted to share this nifty technique I came across for capturing video using the command line. The problem: I have a bunch of old VHS tapes (remember those...?) and need to get them digitized. I have a VCR, and a Dazzle Hollywood DV Bridge which captures video to DV over Firewire (IEEE1394). I first tried using Final Cut Pro, but it wouldn't capture, perhaps because it expects a controllable DV camera, and the Dazzle isn't a DVC device. I then tried my other favorite video editing app, Kdenlive, but it seemed to have the same problem.
I took a quick stab at the other common editors in the repositories (Kino, Openshot, etc.), but no luck with any of them. Then I remembered the dvgrab command, and gave that a shot and it worked, giving me a nice .dv file. However, DV makes pretty big files, which I wanted to compress down to something more manageable. Since I was going to be digitizing hours and hours of tapes, it would be great if I could compress while capturing. A little more googling and I had the answer - you can pipe dvgrab directly into ffmpeg! Here's the command:
the first part starts the capture, in DV1 format, and outputs it to a pipe file. usually you give dvgrab a filename, like
Code:
dvgrab -format dv1 capture.dv
the second part does the encoding:
-f dv: use DV format -i -: input from the pipe -b 2000k: video encoding bitrate of 2000k/sec, high quality -ab 512k: audio encoding bitrate -y: overwrite file if it exists
I didn't set the codec explicitly, for Quicktime it defaults to MPEG4. This worked great, capturing a 2-hour tape into a high-quality quicktime around 2GB. But I also wanted to be able to view the capture while it was going. Since I left the field monitors and audio splitters at the office, I had to figure out how to do this in software. Turns out that the "tee" command does exactly what I needed - the shell never ceases to amaze! Here's the full command:
Code:
dvgrab -format dv1 - | tee >(ffmpeg -f dv -i - -b 2000k -ab 512k output.mov) >(playdv --disable-audio --no-mmap)
tee uses the
Code:
>(command)
syntax to pipe simultaneously to multiple processes. The only thing that didn't work was audio playback, which was choppy and introduced errors in the capture file. I think a little tweaking with the capture rates could fix that.
Up untill this week I used to grab a streamed video from my root/tmp file. Video is nolonger streamed to this file. What has happened? and how can I grab streamed video?
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'm trying to capture video from my Sony DCR-HC21 video camera. I've managed to install Kino fine but was getting the error
aw 1394 kernel module not loaded or failure to read/write /dev/raw/1394 I could get it working by opening as root but then the files belong to root which I didn't want. So I did the following (as suggested in another thread:
chmod 777 /dev/raw1394
And now I get the error "No AV/C compliant cam connected or not switched on"
I've tried so many things ie [URL]
and as I'm a novice I'm reluctant to keep trying random things when I don't really know what its doing.
OK, it's back to the first error, is there anyway to run Kino and capture video without changing to root?
On my Windoze machine, I use Replay Media Catcher 4 which runs silently in the background and captures any videos (FLV, AVI, MPG, WMV, etc) on any websites that I happen to go to, and saves them to a folder on my hard drive. Right now, if I want to save a video that I'm wathing from Ubuntu, I have to go to /temp, guess which file it is, and copy it after it downloads fully but before it finishes playing, otherwise Firefox deletes it from /temp right away. This is a pain.
Yes, there are screen motion capture utilities in the Ubuntu Software Center, but they're just screen scrapers that result in low quality copies without any audio. I want something that will actually capture the video stream and save it as a file. Even if it doesn't save all videos automatically like RMC4, and I have to right click on the video to Save As, that would be better than copying it from /temp at the precise exact moment.
Does anybody know what has happened to Kino - the video capture utility? Used to be packaged by packman for Opensuse but doesn't seem to be available for 11.2.
Is there an alternative I can use for video capture - or has packman just not gotten around to adding this yet?
I'm about to go buy a video capture card this week and was wondering if there's one that's easy to setup in Ubuntu or (ideally) has some official open source drivers available. I'm planning on recording videogame footage and the like from my consoles to edit on kdenlive and upload it to ..... (why? Cuz it can be done. =P). So I'm wondering if anyone has any recommendation before I order one. I'm only interested in SD resolution for the time being.
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.
I am trying to record a test video with my built-in webcam, using Cheese. However, after I click "Start recording," the Cheese screen turns black, and Cheese seems to hang. I can click "Stop recording" sometimes -- then I get a split-second video clip. But mostly it just hangs until I force quit.
I'm on an Asus 900HA. I could record video clips on using eeebuntu and Cheese. Is there a setting I need to check?
I have an Acer Aspire One Netbook, and I have the Ubuntu 9.10 Netbook Remix installed. I have tried using Cheese to capture video and it captures maybe 2 seconds of movement, then goes black and/or the image freezes. I can take photos just fine, but video capture seems to be impossible. Any help?
