[Not really solved] Video with Pidgin is not working

Hi,
I would like to use video chat with Pidgin, but it doesn't work on my computer.
I have a webcam (:D), and it seems that it is correctly recognized because ` vlc v4l2:// ' shows me my face. I'm using XMPP (with a GMail account, but this shouldn't matter) and want to chat with someone using Ubuntu and Pidgin 2.6.6 (she has a webcam which seems to work correctly)
In the "Voice/Video settings" plugin, there are three options in the field Video → Input → Plugins : "default", "Test Input" and "Video4Linux" (and only "default" in the field Device, for the three plugins)
"default" and "Video4Linux" give
(21:03:34) Error with your webcam
(21:03:34) Conference error
(21:03:34) The call has been terminated.
as soon as I try to start a video call, and "Test Input" only shows me a test pattern (but I guess this is the meaning of "Test Input" )
BTW, I wonder why there is only "Video4Linux" and not "Video4Linux2"
The Pidgin's FAQ says this
How do I configure my microphone/webcam?
Currently, the command-line gstreamer-properties program is used. This is only available on GNOME-based systems. On other systems, Pidgin makes its best guess as to which device to use. A plugin is planned to support this functionality on other systems.
But I don't use GNOME, my desktop environment is LXDE.
What could I do to make my webcam work with Pidgin?
Thank you!
Edit:
- my system is up to date
- I have farsight2 and gstreamer0.10-{good,bad,ugly} installed

Well, the problem is not really solved actually.
Pidgin recognizes my webcam but I still cannot open a video chat.
When I try to start a video chat, the following errors are displayed in the debug window :
(17:38:41) mediamanager: gst pipeline error: Could not encode stream.

It seems that my Pidgin want to encode the flux in H264 and the other wants Theora

    Please help me. I don't understand why the script is launched from the sharepoint management shell but doesn't work from the cmd file.

    I have an answer for my problem:  for solving a problem I've made several steps:
    1. Run farm installation under AD admin credentials - runas /user:Domain1\DomainAdmin1 "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN\psconfigui.exe".
    This user has been added as farm administrator in the wizard.
    This user has been added as DBO in the SQL Server. (This is the main difference with my previous attempts)
    2. Execute a command Add-SPShellAdmin Domain1\UserAccount1 in
    the Management Shell of Sharepoint.
    3. Run SQL server and add Sharepoint_Shell_Access to the Domain1\UserAccount1
    (my main account) in the Config database
    4. Run CMD file only from Start->Run menu. 
    runas /user:Domain1\UserAccount1 "C:\1.cmd".
    Do not use Total Commander command prompt or file list for executing *.cmd of *.bat files without root administrator account.
    Thanks all for help.

  • Can you watch really any video with a nokia 9300?

    I tried rm formats and the only that works is sound, no video at all...Am I doing something wrong?. Can you watch really any video with the Real Media player on Nokia 9300?.
    Any help would be really welcome.

    You cannot watch just any type of media file with realplayer on the 9300/9300i/9500 communicators, video files have to be converted to the 3gp format, there are a number of converter software packages on the net - may of which are free. Try also Nokia's own multimedia converter, downloadeable from Nokia, cheers.

  • HELP!!! I am getting really fed up with things that dont work.

    I am asking why a year ago i wasted money on Prem elements 8 only to have it not do the same as prem 2 did not do.
    Neither will see my cameras a canon 650i & sony hc320i which were visible on Win 98 with prem elements 2, i now have win7 loaded Pe2 on both my new laptop & my 2 year old HP desktop the HP crashes if i try to go to DVD burn the Toshiba Laptop just does not see camera or DVD burners.
    PE 8 i thought would be a solution after all its up to date but i hate it as a package oh and guess what it wont see camera or burner so great i wasted my £100+ on something thats horrid to use & wont work. Bring back PE 2 but how do i make it work on both PC,s.
    Pe2 has always been a problem but worked with a lot of messing but now i can only download onto it from DVD then edit slowly ie 15 minutes for every tag on the timeline but having done this it will not see a burner.
    Im not a techy but was told to re load Roxy or Nero missing out bits, i cant see either on my pc,s anyway & dont have the programs to load. the burner works with other programs so my guess is that Adobe just dont add the bits that do the job.
    Well as you can guess i am fed up haveing spent money on something that does not do what it said on th box it just rubbish to expect a mere mortal to play around with a pc.
    Question then is this simple, How do i get this to work properly without getting techy & download to DVD in PAL format and talk to the camera without it crashing my PC.

    Hi in reply to this both cameras are dv video cameras the sony being 3 years old & great the Caon is 5 years old having been bought for the athens olympics. Operating system as stated is win7 that does see the cameras on my lap top. i dont know what other facts you need.
    I have contacted Adobe at least 3 times since buying Adobe PE8 the last time pointing out very unhappily that customer service is about replying to emails. The customer service contact is the one with the original packing. i have to say this is getting me no where. I want it to work when loaded its on a new PC where nothing has been added as one of your colleagues has  there is no'downloaded trash' the only programs on it are those that came with it plus PE8.
    Life & PC's are supposed to be fun this is not. when i have the time to wait for elements to talk to the net 7 crash again i will ask for more help either Windows 7 is rubbish or the link to adobe. sad really

    Subject: HELP!!! I am getting really fed up with things that dont work.
    Your Canon 650i is a still camera. You should be able to download the photos from it using either Photoshop Elements or the Premiere Elements Media Downloader. The video, per the FAQs to the right of our forum, will likely need to be converted before you can edit it in Premiere Elements.
    I could not find any specs on a camera called the Sony HC320i, so I have no idea if this is a still camera, a tape-based or hard drive based camcorder or even an AVCHD unit.
    Beyond that, you really haven't given us nearly enough information to help you out. If you're unhappy with the software, you can certainly contact Adobe by clicking the Contact button at the top of this page.
    Meantime, does Windows recognize a connection to these cameras/camcorders when you plug them into your USB or FireWire port? If not, the issue is with your system. Not the program. Without knowing what operating system you're using, it's hard to advise you beyond that.
    Meantime, have you gone to Premiere Elements Help menu and selected Check for Updates to get the 8.01 patch?
    Have you gone to Windows Update and manually downloaded the non-critical updates to ensure your system is completely up to date?
    Again, if you're as frustrated as you are,  I'm surprised that in the past year you have not contacted Adobe. At the very least, you could have asked for a refund within the first month or so.

  • Videos with no sound - not codec or file type related

    Last night my wife and I were at a concert and she recorded a couple songs on her droid incredible 2. There is no audio when played back on the phone or on the pc. we made sure the 'sound recording on' option was checked so I'm sure that's not the issue.
    i've copied the file to my pc, converted it to every video format known to man and have tried quicktime, VLC, ect. can someone please help me get to the bottom of this? thanks in advance!

    Hello themadstork,
    I know how important it is to be able to capture a memorable moment like this, and can imagine how frustrating it was to find there was no audio attached to the videos!
    I checked to see if anything like this has been reported, and didn't find anything.
    Have you recorded any other videos with your HTC Droid Incredible 2?  If so, was there sound on any of those videos?  Also, when you played the video on your PC was there audio when played?
    Let me know so I can further assist.

  • How to record screen video with sound but not playing while its recording

    Hi, I'm trying to figure out a smart way to record some video lectures using my computer. I note that the Quicktime player is able to do that, but it confines your screen to a certain size so anything that falls into that screen capture zone will be recorded which is fine as i get a separate monitor soon so i can just chuck it one side to record while I'm doing other work.
    But what im still trying to figure out is how the sound can also be simultaneously recorded by the software (be it Quicktime or not) and yet not be playing out loud on the speakers so i can do my work and not get distracted by that.
    Any line-in or some clever way to do that?
    Windows options also possible using parallels if anyone has a solution

    Hey Jeffrey,
    The easy solution to this is through the utilization of SoundFlower (Completely free).
    Here are two tutorials that will guide you through the process of capturing your System's Sound as well as recording whatever is playing on the screen:
    Soundflower Tutorial 1: http://www.youtube.com/watch?v=3M_IBA-xPCc
    Soundflower Tutorial 2: http://www.youtube.com/watch?v=U-5qxNeMl7E
    I hope these tutorials help you out in solving your issue!
    Enjoy.

  • Amazon Instant Video with pipelight: HD not available (HDCP)

    On my 64-bit archlinux-laptop I am using pipelight (0.2.5-2) and wine-silverlight (1.7.14-1) to watch video-streams of my "Amazon Instant Video"-account. Before end of february 2014, the provider of the video-stream-service was called "lovefilm" (Germany) and everything worked fine on archlinux. But now, I cannot watch movies in HD anymore and get this message:
    HD viewing isn't available because the display doesn't meet content protection (HDCP) requirements. This title will continue in Standard Definition.
    Maybe, I made something wrong with my pipelight/wine-silverlight-configuration. On my Playstation for example, I have no problems with "Amazon Instant Video" and HD. I guess, on ms-windows it should work as well. By the way, I am not using an external monitor (VGA-connections can cause HDCP-errors). And as ewaller told me in an e-mail, I should mention in this forum, that my intention is not to crack any copyright-protections but only want to watch my paid movies on my laptop.
    Andreas

    Hi andreas,
    the short answer is: its not (yet) supported with Pipelight. HDCP (or content protection in general) is a feature which is not available with any Linux driver (not even the proprietary ones), and besides that some other features are missing too. Nevertheless this is on our todo-list for future versions of Pipelight, but we can't give an exact schedule, especially as it involves a lot of legal problems and questions.
    For a bit more detailed information please take a look here, where Michael Müller (one of the other developers involved in Pipelight) summarized the current status. You can also subscribe to the bug report mentioned there if you want to be informed about all news concerning this issue.
    By the way: You would encounter exactly the same problem in some situations on Windows, for example when your monitor is only connected via VGA, and thus the video data cannot be securely transmitted.

  • [kde] can not explore DVD video with dolphin

    with KDE 4.14 I don't have the option "explore with dolphin" when I insert a dvd-video,
    it's not normal because with older versions of KDE I had an option "explore/open with dolphin" when I insert a dvd video
    it seems a regression or a problem with kde package in archlinux

    in fact all is ok, the problem occurs only with a DVD in my collection

  • I REALLY need help with this! (not too hard) (but hard to explain) (long)

    I know that this isn't hard, but I just can't figure it out.
    I am trying to create artificial cellular life, but the cells will be able to go through sexual reproduction.
    The DNA for the cells is a 500 index boolean array. One array for Dominant genes, and another one for Rececive genes.
    The DNA is generated randomly.
    The division (to make a sperm cell) works like this -
    1. I get a random number with the Math.random() function, and I use the Math.round() function to round it to either a 1, or a 0.
    2. The boolean arrays are converted to integer arrays (true = 1, false = 0).
    3. If the random number is a 1, then (in a for loop) the current index value of the dominant array is changed to a 3. If the random numnber is equal to a 0, then the current index value of the rececive array is changed to a 3.
    I started working on a new class, to combine the sperm cell with another sperm cell (call it an egg cell, whatever, doesn't matter) in order to create a new complete cell.
    I realized that I have no idea how I can reuse my classes, and make NEW cells, without overwriting my old cells.
    All of the final information that the classes produce is passed through TestMain.class (which puts it into other variables, and sends it to the appropriate class).
    So, I need to be able to run the process for creating a cell, then creating a sperm cell out of it, twice.
    I can, of course, just copy and paste this action, but seeing as how I want to have unlimited amounts of cells in action, this would not be practical.
    Here are my classes, sorry that they are not commented, but I explained what they do above, and I will write what they do overall.
    Genes.java - Creates the random DNA (and is essentially the cell)
    public class Genes {
    public boolean[] domgenes = new boolean[501];
    public boolean[] recgenes = new boolean[501];
        public void randgenes()
    System.out.println ("Dominant Genome: ");
    System.out.println ("");
    int domcount = 0;
            for(int i=0; i<500; i++) {
                double tempgene = (Math.round((Math.random())));
                int tempdomgene = (int)(tempgene);
                  if(tempdomgene == 1) {
                  domgenes[i] = true;
                System.out.print(1);
                  else {
                  domgenes[i] = false;
                System.out.print(0);
              for (int x = 0; x<500; x++) {
                if (domcount == 0) {
                System.out.println("");
                System.out.println("");

                  else {
                  recgenes[x] = false;
                  System.out.print(0);
        public boolean[] getdomGenes()

            return domgenes; //returns the dominant genome
        public boolean[] getrecGenes()
            return recgenes; //returns the rececive geneome
        }DivideGenes.java - This creates the sperm cell out of the information that TestMain.java sent it (which is the information that Genes.java sent to it).

    Thank you very much if you choose to help me out.

    As I said before, your code is not object.
    When you write
    DivideGenes cell2 = new DivideGenes(theDominantGenes, theRececiveGenes);it means than from 2 Genes, you are creating a new object which is DivideGenes. I assume that what you want is to create a cell from an other cell and its mate.
    So it should be:
    public class Cell {
      //put here your gene class attributes and methods
      public Cell divideCell(Cell mate) {
         Cell child = new Cell();
         //put here your divide code
         return child;
    }Otherwise I can't understand your code.
    What kind of object is a createcellGene?? It must be a method of Cell !!

  • In camera on iPad with the iso7 I can not get the video aspect of camera to work., any ideas?

    In the camera app. I can take pics. But when I touch the video ,to change to taking a video it does not let me. All I can do is take pics. Any ideas  of what I can do to make this work.

    It took me a whole to work it out as well, it's not at all obvious. you don't press "video", like any normal person would assume. You have to slide those words up and down. Some of the design choices they have made in ios7 are just plain weird. My favourite is in Game Center... They have hidden the "play game" option behind three little dots.

  • Jerky videos with 30 fps not ideal for Europe with 25 fps?

    When I edit a video (720p 30fps) from my compact camera, Sony WX1, on the iMovie, the rendered video seems to be jerky. (especially if I follow a subject with the camera)
    When I edit a video (1080i 50fps) from my Sony Video camera, the edited video looks fine.
    Is this effect due to the fact that my video is rendered with 25 fps for European TV.
    Does anybody have a solution to my problem?
    Should I rather buy a compact camera that records with 25 or 50 fps instead of 30 fps?
    Any support is appreciated.

    I'm seeing similar problems as you when using my wife's digital stills camera (Canon IXUS 80IS). This records AVI video (640 x 480) at 30 fps. As I'm also in PAL country, I normally use the PAL 25fps setting for my iMovie '11 projects, which are mostly imported from my Sony HDR-SR7 AVCHD camcorder (PAL).
    However, to avoid the jerkiness when creating projects from the Canon footage, I now use the NTSC 30fps setting for clips from that camera. The exported project plays flawlessly on my MacBook Pro and also through my Western Digital TV Live HD Media Player connected to an LCD HD TV. When burning a DVD in iDVD you can choose to encode as PAL 25fps or NTSC 30fps. However I've found that the NTSC version doesn't always work with some DVD player/TV connections. So you will still see jerkiness if burning PAL versions, but these DVDs will at least work with all PAL equipment.
    If you don't intend burning DVDs but simply wish to view by other means (for example, computer, media player or web) it's quite OK to use the NTSC 30fps setting for your projects. These will play fine on sites such as YouTube, Facebook, MobileMe Gallery and similar places.

  • Not really a problem with Firefox per se; just wondering how I set Windows Live Hotmail as my default mail client.

    I am switching from ymail to hotmail as my mail client. I am having a VERY difficult time switching my default mail client to Windows Live Hotmail from Yahoo Mail. Please help!!!!! I have followed all the directions for IE8 but of course they don't work with Firefox. Could you send me in the right direction? Thank you so very much for your prompt attention to this matter.

    I have this soundcard and I have no problems with playback, but some days ago I tried to install and use skype, but I can't figure out how to enable de microphone. I can't find the control using alsa-mixer.
    Any clues?

  • My HP webcam HD3110/3110 will not show my video with Skype. I have a new computer with Windows 8

    My webcam is 4 months old and my computer is brand new.

    What's your computer model?
    What have you tried till now?
    Can you see your webcam in the device manger?
    Do you have the right driver (win8)?
