Programming :: OpenCV - Pixel Format Of Incoming Image Is Unsupported By OpenCV
Nov 6, 2010
I'm using a logitech quickcam pro 3000 on Ubuntu 10.04.
When I run a simple program with OpenCV to display the output from a camera I get the following output:
Code:
A window still opens with the output from the camera, but it seems very low quality and has far less pixels then it should. The camera built into my computer runs the same program with no problems.
My code for the program is simply:
Code:
One further note to make is that I still have the bad quality and low number of pixels with the logitech even when using webcam program. I can seem to find any drivers to update or anything though.
I am a new man on using both of the opencv and debian. In china, few people use debian linux and have nothing paper about how to insall opencv on this os ... Looking for detail step of installation of opencv on this OS?
I've introduced myself to OpenCV a bit now and can do some of the most basic things with it. My current goal is to have a solid color object (say a red ball) and have a camera be able to find that object. Anybody know of any resources to start learning how to do this? Any tutorials/books? Or is there something I should be searching for instead of color detection and tracking that will give me things more in the right direction?
I've a question regarding two camera images. Suppose I've detected 2d window coordinate of 8 markers of an object in a scene in one camera and detected window coordinates of 10 markers of the same object on another camera.
I've detected the marker. It was easy. Now how do i know which window coordinates on two cameras are the coordinates of same marker? I mean there are markers captured on both cameras and some of them are representing the same marker in both cameras. I just like to know which ones are same on both cameras. Is it possible to find that out using opencv?
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 need to run Opencv 1.1 or lower to be compatible with the systems at my University where most of my work is done. 9.10 allowed 1.1 through apt, but before that I remember all kinds of nightmares getting OpenCV to run with FFMPEG. If I go back to self-installing 1.1, am I going to have a repeat of those nightmares? I guess a better way to phrase it, is there any way to get opencv 1.1 through aptitude?
I am learning image processing and hence using opencv-2.2.0. I am following the link [URL] to install this. But even the first command to install build-essential. Code: apt-get install build-essential is giving following errors...
Code: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may resolve the situation: The following packages have unmet dependencies: build-essential: Depends: gcc (>= 4:4.4.3) but 4:4.4.1-1ubuntu2 is to be installed Depends: g++ (>= 4:4.4.3) but it is not going to be installed Depends: dpkg-dev (>= 1.13.5) but it is not going to be installed E: Broken packages
I recently installed openCV using [URL]. I am unable to locate library location to be included while running programs. Does this version of openCV needs libraries to be downloaded externally or they are inbuilt and I am unable to get their location.
I installed Opencv in Lucid.But i dont know how to compile a program (.c/.cpp) by giving additional opencv flags. So i found another method, There is Buildall.sh (given Below) along with the samples in Opencv Source.I copied buildall.sh to my working directory and using it but there is a problem that each time it compile all the source files in the .
But what i need is a "build.sh" file such that it compile only the argument file given from terminal using opencv flags as in buildall.sh. like follows
Code: sh ./build.sh prog.c then it will compile prog.c Code: sh ./build.sh prog2.cpp then it will compile prog2.cpp
its for my project .imy entire project using opensource tools and softs only. if possible somone pls explain the shell script in build all.sh
unable to run opencv opllications on ubuntu(10.04)error:OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file /home/p/OpenCV-2.0.0/src/highgui/window.cpp, line 100.
So I followed all the steps here.[URl].. whixh is basically the same steps as in the installation wiki.The problem is that I can't find the cv.so file in /usr/local/lib/python2.6/site-packages . the folder is empty.
OpenCV doesn't work. I wonder why would anyone create a RPM package and not bother to check whether it actually works? Do they get paid per package at Red Hat? The problem seems to be in cap_ffmpeg.cpp. Somehow, OpenCV cannot resolve the ffmpeg CODEC libraries, but the annoying part is that it compiles and installs error free - it just doesn't work. Without any error messages, it is really hard to figure out what is wrong.
I'm starting to use Ubuntu 10.04 LTS and want to install a Java based language, Processing which uses OpenCv library to perform video issues. [URL]. I'm not familiar with the terminal but willing to be. I'm also not familiar with the file system, I mean I don't exactly know where the archives downloaded are and where they should be to be executed.
I am trying to compile OpenCV 2.0 with ffmpeg (with x264) support on my Ubuntu 11.04 64-bit machine. (Since I want to use the binaries provided by other developers, I have to use opencv 2.0 version)
I followed the guide from: [URL] to compile x264 and ffmpeg manually, and succeeded.
Then I followed the guide in the INSTALL file provided by the OpenCV 2.0 package. I use CMake to configure and generate them, and use "make" command to try compiling. However, I got the following error report, which haunted me for almost half a week.
I am trying to install opencv on ubuntu. I have been following the directions exactly as given in the readme, and all goes well until I enter sudo make install, and get this error:
CMake Error at cmake_install.cmake:61 (FILE): file Internal CMake error when trying to open file: /home/iochinome/workspace/trunk/opencv/release/install_manifest.txt for writing.
I am trying to stream from a webcam to mp4 file with avconv/ffmpeg with the GRBG pixel format. I can find a lot of ffmpeg commands and other stuff on google about a webcam stream to file with ffmpeg, but none of them use GRBG pixel format and are working for me ...
I have never tried something like this before
Output of v4l2-ctl --list-formats-ext: Code: Select allioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'GRBG' Name : GRBG Size: Discrete 162x120 Size: Discrete 324x240
I've searched all over the internet and have found numerous threads on this topic, none of which have helped me fix the problem. I'll post as much info I can about my setup.I have 3 hard drives... one is for ubuntu (9.10), one is for my data, and one is for Windows7. It looks like this:
1st drive (hda) = ubuntu 2nd drive (hdb) = data 3rd drive (hdc) = windows
I've been googling all afternoon to fix this error I get. The situation is as follows: I have multiple harddrives (3x320gb and 1x160gb) all on the SATA interface. One of these drives contains Windows, and the rest I use for programs and downloads. I've installed Ubuntu 9.04 from a USB-stick using the installer's partitioner to make some room for Ubuntu (Ext4 filesystem). I've tried Ubuntu and SUSE in the past.
2.6.38-10-generic-pae ===> Error 16: Incosistent filesystem structure 2.6.38-10-generic-pae (recovery mode) ===> Error 13: Invalid or unsupported executable format 2.6.38-10-generic ===> Error 13: Invalid or unsupported executable format

b08e48b7-1194-49c1-a743-91e7ee90334e is a link to /dev/dm-2 which is my root partition on nvidia raid
PS: At first it did not boot at all dropping out to grub shell, but I managed to boot it with gparted live usb stick and chroot to Ubuntu and re-install grub, but now 2.6.38-8 kernel works and 2.6.38-10 is not
A few days ago I booted up my computer as normal and loaded vista. It loaded fine, but then froze at the login window. I restarted my computer but this time when I tried to load vista I got the "Error 13" message. Ubuntu still loads up fine however.
I'm fairly certain that I'm using Grub - Legacy, and since most posts that I see post the contents of the menu.lst file, I will too Code: # menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8), # grub-md5-crypt, /usr/share/doc/grub # and /usr/share/doc/grub-doc/. ## default num # Set the default entry to the entry number NUM. Numbering starts from 0, and code....

Reluctantly I made a temporary install of XP as follows Remove linux drive and install a wiped drive.format ntfs & install windows xp (w/sp3)shift ntfs drive to slave, replace linux drive as master and xp drive as slave. Add it to grub as follows:
Code: # boot=/dev/sda1 default=1 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz titlem$ Windows XP code....
I was installing opensuse on the c partition and it gave errors so i aborted it now i click on windows and it says invalid or unsupported executable format chainloader +1 so then i proceeded to try and fix this by changing the menu.lst to this:
And now it tells me that disk isnt found so i need to know what to put in the menu.lst to load the actual windows partition and then fix the original error.
I have ripped quite a few movies onto my server and I play them on my PS3 with mediatomb. I haven't changed any of the settings in handbrake except I was playing around with the quality meter on the video tab. Some of my movies will play and others won't. The ones that do not play say something about an unsupported file type. They also will not play in Movie Player.
On my Laptop is an 80 GB HD. I installed Windows XP first (at this point it worked perfectly) then installed on the same HD, but on other partitions Archlinux.
The whole thing looks like this now:
/dev/sda1 <--- Windows xp /dev/sda2 <--- arch linux (/, etc, etc^^) /dev/sda3 <--- homes /dev/sda4 <--- boot partition (grub)
(I got no SWAP partition, I got 4gb RAM (well can only use 3, since my system doesn't support 64bit), and my friend told me there's no absolute need for a a swap :>)
Arch Linux is booting perfectly (and very fast), but Windows XP doesn't want to boot anymore :> (Just if it's from any importance: In the partition program I took the "bootable" flag away from my XP Partition and set it to sda4 - I thought I need to do that, but now I'm not so sure anymore :P )
My entry in the file /boot/grub/menu.lst looks like this (I also tried various others)
title Windows root (hd0,1) makeactive chainloader +1
When I boot and choose the Windows XP in the GRUB boot menu, the following message appears:
error 13: invalid or unsupported executable format
When I set root(hd0,1) to root(hd0,0) (what seemed the most logical to me) and boot again selecting the windows xp, then the GRUB cosole appears.
So what did I do wrong - or better said: what should I do now?
I've been playing around with trying to assemble a bare-bones Linux system on a disk.img file through a loop device. I compiled the most recent stable kernel and then copied it onto the root partition in the image. When I try to boot up into the image using qemu, grub gives me this:
Code: Booting 'tiny' root (hd0,0) Filesystem type is ext2fs, partition type 0x83 kernel /boot/vmlinux Error 13: Invalid or unsupported executable format
Press any key to continue... I am confused because I compiled the kernel with 'make bzImage', and the architecture hasn't changed (qemu on the same machine used to build the kernel). So it should be bzImage format. Is that what this Error 13 means, or could it means something else is wrong...?
I have a weird problem with one of my servers (normal PC hardware). I was connected remotely using Putty, doing some stuff, and all of the sudden some commands, like "ls" stopped working, giving a "file or command not found" type of message. I restarted the ssh session, only to find out I couldn't log on any more (access denied). When I got home and rebooted the system, I was greeted with this:Booting 'CentOS (2.6.18-194.el5xen)'root (hd0,0)Filesystem type is ext2fs, partition type 0x83kernel /boot/xen.gz-2.6. 18-194.el5Error 15: File not foundPress any key to continue...Then I searched about this, found out that the files in /boot/grub/menu.lst did not exist at the specified location (/boot/xen.gz-2.6. 18-194.el5). Somehow I managed to find them in another place, copied them in place, and now I get:Error 13: Invalid or unsupported executable format
i have just discoverd i can't enter my windows 7 via grub boot menu i get error 13 Invalid or unsupported executable format what can i do? # This entry automatically added by the Debian installer for a non-linux OS # on /dev/sdb1
