Ubuntu Multimedia :: Opencc Highgui Error Out Of The Blue?
Apr 12, 2010
so i am developing an application with opencv and i suddenly got this error out of the blue-HIGHGUI ERROR: V4L2: Pixel format of incoming image is unsupported by OpenCVUnable to stop the stream.: Device or resource busyUnable to stop the stream.: Bad file descriptorHIGHGUI ERROR: V4L: Pixel format of incoming image is unsupported by OpenCVeverything was working, then it reverted to giving off this error. the webcameras that i am using both work with guvcview. (but, another error that somebody might be able to instruct me on, they cannot both stream at 640 by 480p at 30 fps whereas they previously could... the error it gives is
VIDIOC_STREAMON - Unable to start capture: No space left on deviceVIDIOC_STREAMON - Unable to start capture:
When i try to install Fedora 15 on a clean machine it freezes as soon as the pixelated load bar with the white, light blue and dark blue colors show.
I have tried several different versions of Fedora (64bit and 32bit) and have tried to burn it to a CD and/or DVD (For the larger version) and copying it to a usb pen with universal linux usb, liveUSB creator (from Fedora) and last one i don't remember the name on.
I esablished a dual boot with Windows 7 and Ubuntu on separate partitions. Then, as I realised that Windows 7 was rubbish and Ubuntu annoyed me by losing wireless connectivity after an update, I decided to go back to Windows XP for a while. So I did what I probably shouldn't have done, and formatted the partition (or so I thought) with Ubuntu on, using Windows.
Now, on booting up the system, all I can get is the Grub Rescue prompt and nothing in the Bios menus seems to be of any assistance.
I've tried booting XP from a CD, but a blue screen error always occurs at the same point in the installation. I wonder if I should make a CD/external drive with Ubuntu on, reinstall it, and go from there?
I must have inadvertently changed a color setting in Ubuntu. Suddenly, the color in all video that I play is distinctly blue (human skin is shades of blue and green). This happens to multiple videos in both VLC and Movie Player. It does not happen when I play the same videos on VLC in Windows. Pictures and all other graphics appear completely normal. I am still quite new to Ubuntu and I've never encountered anything like this before. I have no idea where to start
When trying to playback DVDs in VLC media player, I have to switch the video output driver to get any playback.If I leave it on "Default" (which I think is defaulting to "XVideo Extension Video Output"), I get a solid green or blue screen (which I also get with "Xvideo Extension Video Output")If I switch it to "OpenGL Video Output", I get proper DVD playback but it is kind of pixelated and ugly.If I switch it to "X11 Video Output", I get DVD playback that is very crisp and sharp, the image quality is great.unfortunately, the colors are completely messed up and the blue is completely saturated.I've played with the color settings (especially the Hue setting), but I can't get the colors to look right.
I'd really like to use the x11 video output since the quality is the best, but I can't get the colors right.the first one (Screenshot.png) is OpenGL output, and the second (Screenshot-1.png) is X11 output.It's also worth noting that I am on an IBM ThinkPad R32 with an ATI Mobility Radeon 7000 (or M6, or M6 LE, whatever you wanna call it).I'm running a fully updated 9.04 Jaunty installation.
After installing all the codecs etc for restricted formats as well as the ATI video card drivers all videos appear very blue. I cannot seem to find anything on here or on the net that would suggest a work around.
This only seems to be the case in VLC, others seem to be OK.
It seems to have only recently starting happening. I've tried VLC and Movie Player, and different types of format such as AVI and 3gp. Anything I could try to eliminate things?
i have just recieved some updates to my system, after the updates my video players are all showing movies in blue. online videos are fine but all my videos on my laptop are blue.
I have a samsung vibrant. I can play my music files over one of my work computers via blue tooth. but have been able to do the same with my home ubuntu 10.04 computer. oddly enough.I can connect to the phone and see all the folders on the phone but I cant see any files.also, I can download files to the phone but not up from the phone. am i missing something that enables playback over blue tooth? or is it simply something that windows has zeroed in on that linux hasn't as of yet?
I have just insall Jessie but I have a blue screen debian with three logos in the midle: harddrive, tools, browser, but no link no menu, only the console.
I have install KDE
my graphique card is VGA compatible controller: NVIDIA Corporation G72M [Quadro NVS 110M/GeForce Go 7300] (rev a1)
I have small problem with GNOME in Wheezy (trying it out just for fun). Whenever I start GNOME Shell and open any window, I get only blue color where windows should be. Entire window is just blue. Shell starts fine. GNOME Classic starts and works well too, even better than MATE in Jessie. My graphics card is old NVidia GeForce MX 440 8x AGP. I suspect it is causing problems.
Kernel is Wheezy's 3.2.
Found this: [URL] ....
I'm afraid I can't use GNOME Shell in Wheezy. Might try Jessie's version instead.
I got out my old Fuji Finepix s3100 and set it to web cam mode to see if anything had changed in the world of usb video drivers. Lo and behold it worked! I can watch myself on cheese web cam booth. kewl, but I wanted more. So, just recently hearing about chatroulette on the Daily Show, I click and wahla no go . After flash comes up and asks for and receives user permission to access my hardware, I click to find a random stranger, and my camera displays yellow and blue lines across its onscreen display box. I notice that movement is noticed by the camera. If I move I notice a change in background/lines. As far as I can tell, my camera is not a fault. I mean it works for local viewing. Is this a flash or possibly a chatroulette problem?
-Ubuntu 10.04 with MPlayer/Smplayer & VLC installed via the repos. -Installed the Ubuntu Restricted Extras package (everything except flash, extra fonts, & java) & w32codec packgae (medibuntu). -Computer in question is 800mhz Celeron, 256MB RAM & one of those basic Intel Integrated Graphics Chip. I'm having problems playing some video files. When trying to play these files with Smplayer, I get a blue screen but can still hear audio (default video output). After switching the video output to x11(slow), I can now see the picture but it's not playable (some video will show maybe one frame every 2 seconds, some video would play for half-a-second then just freeze). This happens mainly with large files (not 100% accurate, but in general files over 300MB).
Mplayer log gives the "Your system is too slow to play this file" & "Bad alloc:insufficient resources" messages. So I'm guessing this is not a codec problem, but a system resources problem? Is there any option, trick, tweaks, etc. I can use to play these problematic files or is it just not possible because of my system specifications? Is there a way I could tell mplayer to play these files with lower bitrates & resolution? Maybe this could reduce the resources needed to play?
The Green jack for audio of the sound card is dead. The other jacks [Blue and Pink] are not working for audio. I have them working as audio outputs in windows xp-using the Realtek interface.How can I do the same in Ubuntu?
I have a rocketfish RF-NBCAM webccam but it doesnt seem to work as it should be, the image is dark and the blue light infront of it that helps with low light enviroments is not working. i have found some drivers for other ubuntu distros but i have the dependencies trouble.
I installed OpenCV and am trying the example programs. When I try to compile like in the tutorial it is not finding highgui.h.I have 64 bit Mint if that helps at all
I'm trying to produce some screenshots of the screen in which there's a window playing a video in avi format. The problem is whenever I take a shot, the video window appears 'solid blue' in the output image. Is there any way or program with which I can capture the current frame of the video
All the people in all the videos I try on my computer (even in vlc) are blue. and so are a bunch of other stuff. I dont know how to fix this. I tried uninstalling the video card drivers and playing the video. Then I reinstalled it. I also tried it in many different media players. I even tried different codec packages.
I created a USB stick with Ubuntu 9.10, used it to boot a dell Inspiron 1550 laptop which has WinXP. I tested 9.10, everything went fine out of the box so to speak. But when I went back and tried to boot XP again I got a blue screen. XP starts in safe mode and no apparent problems are detectable but it will not start in Win normal mode anymore.
Just upgraded to 10.04. Screen is now unusable. It's like looking at it through a blue filter. It seems to be averaging the brightness. if there is a large dark area of screen real estate the paler sections getbrighter.The very bizarre thing is, if I switch user, whilst the theme is different, the brightness problem is gone...
Is it possible to change the blue login background of Lubuntu like we can do in Ubuntu? In Ubuntu we can use Ubuntu Tweak or GNOME appearance properties but how can we do it in LXDE?
I've got virtualbox running on 10.04. I install windows xp on it and everything goes smoothly. I installed it from an iso of XP, however, on the very first boot it says "Windows could not start normally" and gives me the option of safe mode, networking, or starting normally. No matter what I pick it just blue screens for a split second and restarts.
While I was trying to install a package in the package manager I accidentally removed a package that I am not aware of.I got a crash report telling me to enter something along the lines of a broken package repair mode. The next time I started my computer it froze at the blue screen with bubbles after login.Is there a way to access the gui using a recovery/rescue type mode so I can access the package manager, or is there a way to find and reinstall the vital package?
So i have two wireless interfaces. One is a built-in wifi card (atheros) and the other one is a USB antenna (realtek). right now, i'm a little bit far away from my router, so I use the antenna which has a wider range. usually, atheros finds few or none access points. But (see attached screen shot), it began displayed new APs with weird characters in it. What do you think it is? Also, what does the symbol circled in blue means (out-of-subject, i know ...)
My wallpaper, regardless of what is chosen, flashes to blue/green (like an old Win95 desktop color) every 10-15 seconds. It stays that way for a second, then goes back to what is set. Also, it seems to 'fade in' to the blue/green, then fades back to the chosen wallpaper (albeit a very fast fade). Icons on the desktop are unaffected.I've tried disabling all desktop effects, and it still does it. The only way to stop it is to reboot, which seems to fix the problem for 24 hours or so, then it starts again.
I deinstalled Ubuntu today. Just deleted the partitions etc and thought it would be fine, but now this weird grub thing is telling me:
error: no such partition
grub rescue>
I am at the end of my wits: I downloaded a liveCD, which will not boot. My XP cd boots but gets a blue screen afterwards I downloaded a windows 7 live cd which did not help either
Problem is, I can't load my bios anymore to change the boot order... Didn't even know Grub was part of linux...
Point is, I got a presentation tomorrow and all my important files are on that laptop. . . the setroot=(hd0,0) gives no response. I tried a bunch of other commands but I keep getting unknown command...
I have had Xp on my pc for a number of years, and have just installed Ubuntu as a dual boot os. I had a bit of trouble installing GRUB, but that's been resolved. My real problem is that now, after reinstalling GRUB, windows crashes at shutdown with a blue screen, as follows.
Code: 0xc0000021 {Fatal system error} Windows logon process system process has unexpectedly terminated with a status of 0x0000000 The System has been shut down
Everytime I shut down my netbook the blue Kubuntu Screen comes instead of the Red Ubuntu Screen. I don't want the Blue Kubuntu Screen, I want the RED Ubuntu Screen. How do I do this? I tried installing KDE and KDE for netbooks, and KDE default settings (all from software center). What else do I need to do to get rid of this blue screen?
