Hi, I have done a lot of reading about using OpenCV with libjpeg-turbo on BBB and C920.
I'm running Ubuntu 12.04 with LXDE on BBB. I compiled libjpeg-turbo from source, I tried many version, 1.3.1, 1.3.0, 1.1.90 (of course I clean up before trying another version). But OpenCV seems to not recognize /opt/libjpeg-turbo/lib/libjpeg.a. After running ccmake, in Media I/O, JPEG is reported to use /opt/libjpeg-turbo/lib/libjpeg.a (ver ). Yes, the version info is missing, like that the library is not valid. Even with version info missing, OpenCV compiled without any error, but performance is poor. I can run "time ./framegrabber -f mjpg -H 480 -W 640 -c 1000 -p" in ~34 secs, pretty close to 30 fps, but CPU usage is ~65%. Thank you for your time. I appreciate any help :) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
