Can't `cat /dev/video`

I've been trying to do this, but I can't find anything to help.
16:24:48 cha0s6983@localhost:/usr/bin$ ls -l /dev/vide*
lrwxrwxrwx 1 root root      6 2009-09-14 23:29 /dev/video -> video0
crw-rw---- 1 root video 81, 0 2009-09-14 23:29 /dev/video0
16:26:17 cha0s6983@localhost:/usr/bin$ cat /dev/video0
cat: /dev/video0: No such device
vlc and xawtv are showing me a capture screen just fine... my deal is I want to stream the webcam output to stdout, but I just can't figure out how to do it.
Any help very welcome, thanks!
P.S. First post, hi ^^

I suspect this is an issue with YouTube.
It goes down from time to time.
Try it again, click refresh button.

  • "cat /dev/audio" as solution to strange audio-noise?

    With my Macbook Pro (2,2), I hear a strange noise when I connect a loudspeaker to the earphone output that isn't there when I use the internal loudspeakers.
    The issue vanishes when I listen to music for example. And appears again as soon as I clouse the player.
    interestingly, when I enter "cat /dev/audio" in a console, then the noise disappears! And I can still listen to music and everything else!
    I see then many lines of something like "
    |z{{{{{{{{|{{{{{{z|{z{{{|{{{{{{{|{{|{{|{{{{{{{|{{{{|{{{{{{||{{|{{{{{|{{{{{|{{{{{|z{{{"
    Any idea what the problem could be?

    ebonyhack!!! You genius!!!
    I've recently bought brand new quad core beast, with loads of memory, twin 20" cinema screens, apogee duet, Logic Pro Studio 8, Novation keyboard with automap. The reason I bought this lot was because it is all designed to work seamlessly with each other. And with a mac (my first ever), it wouldn't have all those lovely windows / PC issues I had to put up with for years.
    Setup was an utter doddle - easy peasy - it all recognised the other components and worked like a dream, until ............................... first song, three instruments, three audio tracks, HUNDREDS (I am not exaggerating) of error message 10011! It is impossible to record vocals when the darned track keeps crashing! Vocalists get very annoyed. Critical listening to your mix is a complete joke, so you waste hours - no - days of your life bouncing, listening, changing the mix, bouncing, etc, etc, etc.
    I have gone through so many of these threads, trying all the "fixes" offered, with no success at all.
    Just read this thread, unticked that I/O box, loaded up three songs into memory (just for fun!), played the one which crashed most frequently, waited, and waited .............. and waited - and it played right through! First time since I'd got more than the first track or two written! Did the same with the next song - worked perfectly!!!
    Early days as yet, but thanks so much - I love you.

  • [SOLVED] output VC/tty = xterminal ? (cat /dev/?? or something?)

    Hi!
    I'm trying to access the output shown in vc / tty in X. Just "cat /dev/tty1" in an xterminal seems to be way off track, so is "cat /dev/vt/1"... any hint on how to do it right?
    Thx!

    - /dev/tty# are all readable (but not working)
    - /dev/vc/# have the right permissions - can access all the user is logged into, none else (still, wrong folder, but that "right permissions"-thing did catch me).
    In this scheme
    - /dev/tty# are symlinks to /dev/vc/#, and always shows as "lrwxrwxrwx", don't care.
    But tty devices not are for the "capture" purpose
    a better "cat" is to use "fold" or better setterm
    fold -w80 /dev/vcs12 (current scheme)
    fold -w80 /dev/vcc/12 (devfs scheme [Arch Linux])
    setterm -dump 12 -file /proc/self/fd/1
    PS: Because a bug, there no anymore vcs1 and vcsa1 in 2.6.30. http://lkml.org/lkml/2009/7/10/369

  • I can not view ANY videos on Vimeo, I have 'reset' the Ipad, original IOS 5, cleared the history and cookies, I have changed the DNS number to 8.8.8.8, I have worked on this for 2 days and still can't find a fix, HELP!!

    I can not view ANY videos on Vimeo, I have 'reset' the Ipad, original IOS 5, cleared the history and cookies, I haves changed the DNs number to 8.8.8.8, I have worked on this for 3 days now, HELP!!!!

    Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps BEFORE doing the reset.

  • Can't play the video in my Lumia 520

    Hi
    I always love the work of nokia and this time trailer app is just Nice but there's a problem.
    I have downloaded 6 trailers and only 1 is able to play.
    Rest of them says "sorry we can't play this video on your phone".
    I have no idea what's wrong with my phone.
    Please help.
    I have a Lumia 520.
    Thanks in advance.

    Hi @livinglife,
    Welcome to Nokia Support Discussions! 
    What is the error message displayed when you try playing the video? Have you tried using mobile data? If yes, does it show the same issue? What fixes have you tried so far? By the way, are you using the same phone model? 

  • How can I transfer a video recording from iPad Mini to PC?

    Hello Good People,
    I've got an iPad Mini running ios 7.1.2.
    I've got a Windows laptop running Windows 7 with iTunes 11.3.1.2.
    I recorded a video of an interview with my elderly mother which I want to transfer to my laptop for editing and saving for the family.
    I'd like to use Sync but Sync scares me every time I look at it that it will start erasing things from one place or another.  Looks like the unstated assumption is "Sync" from PC to iDevice, not the direction I want to go.
    So, I've done the google searching and haven't found anyone answering this issue but I've found dozens of adds from third party software I can buy to do what apple should provide for as a foundational, basic capability which leads me to think that they have purposefully not given people this capability for some reason.  The iPad Mini also doesn't appear in Windows Explorer so I can't find the videos myself.
    Anyone have a blessedly simple way I'm just not seeing?  Is it safe to use Sync and not lose this precious video forever after it flashes its warning of erasing things?
    Thank you!
    Jim

    Okay, I figured out that Windows has "AutoPlay" settings which can automatically download photos and videos from a newly connected device, such as an iPad Mini.  I think I could open it in Windows Explorer too that way but the auto download solved my problem.

  • Greetings, I am working in Final Cut Pro 7. In the timeline some clips show as offline. I tried going to sequence and reconnecting to media but it does not work. I can still see the video in the timeline and work with it. It just has the red box.

    If the clips are not actually missing, you could try to refresh the timeline by using cmd-0 and then going to the timeline options tab. Then select name only where it says "thumbnail display". Press ok to accept the change, then repeat the process to add thumbnails back to your timeline.

  • Hello can some please help I am trying to watch my HBO go on my apple tv I have sound not picture. I can watch my iTunes videos and youtube so I know it works. it is working

    Hello can some please help I am trying to watch my HBO go on my apple tv I have sound no picture. I can watch my iTunes videos and youtube on my airplay with my ipad and everything is updated so I know it works. But not on HBO go, Max go, showtime go.

    What you want to do does not work with an iPd running iOS 5. See the screenshot.
    The latest update for HBO GO does allow for AirPlay on Apple TV - sound and video - but only on devices running iOS 6 and Apple TV running 5.1.1 or later - according to the app description.

  • I tried to download video from RCA Small Wonder EZ201 to my new macbook pro.  Macbook pro recognizes the device but then message appears that device was improperly ejected when it is still connected. How can I download these videos?

    When I connect the RCA Small Wonder to my MacBook Pro, the device is recognized in finder as EZ201.  I tried to copy the video files in the folder but within a minute or two, I receive a message that the disk was ejected improperly, even though the device is still connected.  I was able to download the first few videos before it stopped working and was able to play them using Perian.  However, when I tried to connect the device again, it froze my system and I had to force a shut down by turning the computer off. Why is the device initially recongized but then shows as improperly ejected when it is still connected? How can I download the videos if the MacBook Pro won't allow the device to stay connected?

    A picture of a screen that suggests my new MBP Retina never connects to the "Macbook Pro backup ("StefanTimeCapsule")
    This is the one that has the files for the backups procured by the Time Machine program. But it can't "connect"-- You 'll see int he sideways pic (sorry!) that the options STILL says "connecting"
    Do i have to make these Time Machines more open to connection?

  • Pre Lion iPhone videos show Thumbnail but can't play - new video generates Unsupported Video Format popup, no thumb but will play via quicktime

    This is really frustrating -
    Over the last year I have been uploading all of my photos and occasional iPhone video to Aperture 3 (latest version all patches in place).    Aperture would recognize the video, create a thumbnale and otherwise treat it nicely.
    Now, since upgrading to Lion I find that though I can "see" the old videos in their folders or projects and the associated Thunbnale, I can't play them - I either get the spinning color wheel and then nothing or Aperture will crash and report an error relating to Quicktime (sorry don't have an error code at the moment).
    If I try and export a video I can - but what I get also can't be played by Quicktime - just a black screen.  When I hit Play - the scroll bar moves, but there is no sound or video.
    From Final Cut Pro X, I can imoprt this exported video file and see that it appears complete - but FCPX uses it's own playback elements.
    If I shoot a new video on my iPhone, I find that I can see the thumbnale in the import option of Aperture when looking at the phone, but once imported I get a Popup telling me that it is an "Unsupported Video Format" - "Do you want to open this video clip with QuickTIme Player?"   If I hit Open then the clip does play, but the thumbnale remains a black square with the warning Exclamation Point.
    I have also had some issues with Lion Mail crashing when trying to play a video made on an iPhone and sent to me via email.   Seems more likley to be a Lion / Quicktime issue then an Aperture and Mail issue - but who knows.
    I spent 2.5 hours of quality time with the Genius bar this morning.  We reinstalled Lion and after that the suggestion was to trash and re-install Aperture, but that would require my disc and of coruse a trip home.   Mail doesn't seem to still have the issues with iPhone movies that it had - but Aperture is still not happy.
    Did as instructed and dragged Aperture 3 to the trash, did the empty trash option, restarted and reinstalled.   Then did a software update to catch the new update for Aperture and it found that.   Interestingly when I did start it up after that it DID NOT ask me for my key - so clearly some elements were left over.  
    Now upon retstarting Aperture 3 once again I find that I can still see my old movies (their thumbnails show up) but I still can't play them.   The new test movie is there but still generates the popup regarding it being an Unsupported Video Format.
    And it's not just my iPhone.   Video sent via email from another iPhone can play as an attachment, or when dragged and dropped to the desktop, but once imported into Aperture is once again proclaimed to be an Unsupported Video Format.  
    Hoping someone out there knows how to resolve this....

    For some reason it just started to work now. Have no idea what didn't work before.

  • HT2506 After updating my system to Mountain Lion 10.8.2 I can no longer view videos on Facebook or other sites. The only one I can view videos on is youtube. I have downloaded Adobe Flash player and still no luck. I cannot even open Preview on my computer

    After updating my system to Mountain Lion 10.8.2 I can no longer view videos on Facebook or other sites. The only one I can view videos on is youtube. I have downloaded Adobe Flash player and still no luck. I cannot even open Preview on my computer anymore. Any ideas would be helpful thanks

    Merely clicking the Preview icon in the Dock doesn't cause it to open anything, unless you had one or more windows open the last time it quit.
    If you're sure you've installed the latest version of Flash, take each of the following steps that you haven't already tried. After each step, relaunch Safari and test.
    1. If you're getting a "blocked plug-in" error, triple-click the line below to select it:
    /Library/Internet Plug-Ins Right-click or control-click the highlighted text and select
    Services ▹ Open
    from the contextual menu. A folder should open. If there is more than one item in the folder with the words "Flash Player" (not "flashplayer") in the name, open the respective Info windows, check the version numbers, and delete all except the latest. You may be prompted for your login password. If you get the same error after doing that, re-download and reinstall Flash. Download it from this page:
    Adobe - Install Adobe Flash Player
    Never download a Flash update from anywhere else.
    2. If you get a "missing plug-in" error, select
    Safari ▹ Preferences... ▹ Security
    from the Safari menu bar and check the box marked Enable plug-ins.
    3. Select
    Safari ▹ Preferences... ▹ Extensions
    from the Safari menu bar. If any extensions are installed, disable them.
    4. In the Safari preference window, select
    Privacy ▹ Remove All Website Data
    Close the window. Then select
     ▹ System Preferences… ▹ Flash Player ▹ Advanced
    and click Delete All. Close the preference pane.

    how can i detach the video from a clip so i can only use the audio when using imovie?

    First, go to iMovie/Preferences and enable the Advanced Tools.
    Import the video clip into an iMovie Event. When you get ready to use it in an iMovie Project, select the clip in the Event and drag & drop it on top of a video or photo clip in the project at the place where you want it to begin. When the pop-up menu appears, choose Audio Only.
