Hi all, I am trying to make a video capture application with OpenCV and QT in Beaglebone Black RevC(with Debian Jessie image). When I attempt to run the application in Beaglebone black, the following errors are shown. *CMEM Error: init: Failed to open /dev/cmem: 'No such file or directory'TIOCL FATAL: The cmemk kernel module is not installed. Consult the OpenCL UserGuide at http://software-dl.ti.com/mctools/esd/docs/opencl/index.html <http://software-dl.ti.com/mctools/esd/docs/opencl/index.html>*As per the link* https://www.mail-archive.com/[email protected]/msg42027.html <https://www.mail-archive.com/[email protected]/msg42027.html>, *I tried to solve the issue. But the problem is not solved. Also the following links shows the TI AM335x doesn't have a GPU in it. So it cannot support OpenCL. *1) https://groups.google.com/forum/#!topic/beagleboard/pZpc5egCaUw <https://groups.google.com/forum/#!topic/beagleboard/pZpc5egCaUw>.2) https://e2e.ti.com/support/embedded/linux/f/354/t/500780 <https://e2e.ti.com/support/embedded/linux/f/354/t/500780>*But is openCL necessary for videostreaming applications ? Whether openCV is sufficient for that? Is there any video streaming applications which does not use openCL. What I understood is openCL is only for parallel processing? Whether it is necessary to use Beaglebone X15(in which openCL is supported) to run a video streaming applications? No OpenCL isn't required to run OpenCV. There just happens to be an OpenCL option to accelerate OpenCV. But that doesn't really matter for the beaglebone black as you'll need to do OpenCV in software.. Or upgrade to the BeagleBoard-X15...
