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.

Programming :: OpenCV - Color Detection / Tracking

Oct 14, 2010

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?

Programming :: Opencv Related - Find Out Corresponding Points Of Same Scene On Two Cameras?

May 2, 2011

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?

Ubuntu :: Any Way To Get OpenCV 1.1 Through Aptitude?

Jun 9, 2010

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?

Ubuntu :: Shell Script For Opencv Compilation?

May 30, 2010

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

Fedora :: OpenCV Cannot Resolve FFmpeg Codec Libraries

May 19, 2011

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.

Ubuntu Multimedia :: Compile Errors From OpenCV With Ffmpeg + X264

May 29, 2011

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.

Code:
Linking CXX static library ../../lib/libhighgui_pch_dephelp.a

Scanning dependencies of target pch_Generate_highgui

Debian :: FFMPEG And Webcam With GRBG Pixel Format

Jun 10, 2015

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 324x240

How to get this working?

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.

Ubuntu Multimedia :: Handbrake And PS3 - Won't Play Due To Unsupported File Type - Format

Feb 11, 2010

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.

Installation :: Can't Boot Windows (GRUB) / Invalid Or Unsupported Executable Format?

Feb 1, 2010

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?

General :: Booting Into Kernel - Error 13: Invalid Or Unsupported Executable Format

Sep 13, 2010

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 restarted the ssh session, only to find out I couldn't log on any more (access denied).
