The error i get is VIDIOC_QUERYMENU: Invalid argument HIGHGUI ERROR: V4L: Property (5) not supported by device libv4l2: error turning on stream: No space left on device VIDIOC_STREAMON: No space left on device I know the problem is coz of the usb hub as the hub puts all the usb hub devices on to the same bus. The code works fine if the cameras are connected over the native ports than through the usb hubs, I wonder y.. isn't there any way out thorough this..??

theoretically usb 2.0 is capable enough of sending 60MB/s of data through it.
but whenever i try to stream, it Throws up a error.
The error i get is
VIDIOC_QUERYMENU: Invalid argument
HIGHGUI ERROR: V4L: Property (5) not supported by device
libv4l2: error turning on stream: No space left on device
VIDIOC_STREAMON: No space left on device

I know the problem is coz of the usb hub as the hub puts all the usb hub devices on to the same bus. The code works fine if the cameras are connected over the native ports than through the usb hubs, I wonder y..
isn’t there any way out thorough this..??

The arm toolchain is downloaded from CodeSourcery. As instructed above I am making the following changes and going ahead. Since the CMUCAM toolchain is EABI and am working on linux x86 machine; The settings for me are as follows - [/code] # #### Linux host. EABI complier # #export DEVROOT=~/home/vikram/CodeSourcery/Sourcery_G++_Lite # #export APP_PREFIX=arm-none-eabi # #export GCC_HOST=i686-redhat-linux-gnu # ##-O3 kills gcc : cvpyrsegmentation.cpp:1021: internal compiler error: in verify_local_live_at_start, at flow.c:546 # #export OFLAGS=-O2 [code /] The configure is taking successfully. But I am getting errors while make - ing the code. The errors are as follows - [/code] cxerror.cpp:96: error: 'pthread_key_t' does not name a type cxerror.cpp:424: error: 'g_TlsIndex' was not declared in this scope cxerror.cpp:424: error: 'pthread_key_create' was not declared in this scope [code/] The similar problem has been encountered before and I think this error is due to some lame mistake which am unable to think about . Please help ! vikram Hi

The configure is taking successfully. But I am getting errors while make - ing the code. The errors are as follows -

[/code]

The similar problem has been encountered before and I think this error is due to some lame mistake which am unable to think about . Please help !

I try cross compile OpenCV-2.0.0 While "make"(after ./configure --host=arm-linux --disable-shared ) I get some error /usr/local/arm/4.3.2/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.2/../../../../arm-none-linux-gnueabi/bin/ld: cannot find -lgtk-x11-2.0 May be the problem in my toolchain? Hi,Igor!
I try cross compile OpenCV-2.0.0
While “make”(after ./configure –host=arm-linux –disable-shared ) I get some error

/usr/local/arm/4.3.2/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.2/../../../../arm-none-linux-gnueabi/bin/ld: cannot find -lgtk-x11-2.0

May be the problem in my toolchain?

Or totally irrealist ? Thanks Fred Hi Ygor

Do you think with mini 2440 that would be possible to perform a live blob tracking (white dot on black background) at 30fps for a 240*240 video from cmos cam ?

Or totally irrealist ?

Thanks

I have a question for you, regarding cross-compiling GTK. I am trying to cross compile OpenCV programs for the BeagleBoard xM (ARM8). I have configured OpenCV by removing "--without-gtk". This should mean that the cross-compiled program will have gtk support, right? However, how do I cross compile GTK for ARM on an Ubuntu 10.04 machine? I searched the net a LOT, but there are no real good guides - and I'm a beginner to linux. Could you help me out with this? I cross compile using this command: rex@ubuntu:~/Desktop/Project$ arm-none-linux-gnueabi-g++ -O2 -I /home/rex/Desktop/Project/opencv/include/opencv facedetect.cpp -L/home/rex/Desktop/Project/opencv/lib -lcv -lhighgui -lcxcore -lml -lcvaux -lrt -lpthread -ldl -lz -lpng12 -ljpeg -o facedetect -static I'll really appreciate your help. :-) Hey Igor! I have a question for you, regarding cross-compiling GTK. I am trying to cross compile OpenCV programs for the BeagleBoard xM (ARM8).

I have configured OpenCV by removing “–without-gtk”. This should mean that the cross-compiled program will have gtk support, right? However, how do I cross compile GTK for ARM on an Ubuntu 10.04 machine? I searched the net a LOT, but there are no real good guides – and I’m a beginner to linux. Could you help me out with this?

I cross compile using this command:

rex@ubuntu:~/Desktop/Project$ arm-none-linux-gnueabi-g++ -O2 -I /home/rex/Desktop/Project/opencv/include/opencv facedetect.cpp -L/home/rex/Desktop/Project/opencv/lib -lcv -lhighgui -lcxcore -lml -lcvaux -lrt -lpthread -ldl -lz -lpng12 -ljpeg -o facedetect -static

I’ll really appreciate your help. :-)
