+13:59 < jtanx> ...
+13:59 < jtanx> I brought the bbb home
+14:00 < jtanx> booted it off an ubuntu image, and uvccapture can take 800x600 images fine from my webcap
+14:00 < jtanx> webcam*
+14:00 < jtanx> I don't know if it's because it's a different camera, or because it's a different os
+14:34 < jtanx> I just tested with the api/image and I can get 800x600 fine
+14:34 < jtanx> too
+14:38 < jtanx> I can even do 1600x1200 images just fine
+14:38 < jtanx> ................
+14:38 < jtanx> ._.
+14:38 < jtanx> I'll be bringing this in tomorrow, see if it works with the cameras that we're going to be using
+14:39 < jtanx> Since my 1gb sd card was not big enough to opencv, I've actually flashed the internal memory with ubuntu
+14:39 < jtanx> (so I could install opencv)
+14:41 < jtanx> wowthat is so stupid
+14:42 < jtanx> so either it's the cameras that we bought, or the os
+14:42 < jtanx> but it works at 1600x1200
+14:42 < jtanx> (max resolution of my webcam)
+15:00 < jtanx> ok, I just tried it with the os we've been running before (on your 32gb sd card), and it also works at 1600x1200
+15:00 < jtanx> so it's an issue with the camera
+15:01 < jtanx> (e.g selecting a camera that actually works with the BBB

+09:17 < jtanx> ....
+09:17 < jtanx> I just ran the bBB with ubuntu and used the usb microscope
+09:17 < jtanx> and it worked
+09:18 < jtanx> and so too does it work on the original os
+09:18 < jtanx> wtf
+09:33 < jtanx> hahahaa
+09:33 < jtanx> it crashed because it ran out of memory
+09:33 < jtanx> I tried having both cameras at once
+09:33 < jtanx> and switching between them
+09:34 < jtanx> but other than that it works
+09:34 < jtanx> this is weird
+09:44 < jtanx> about 1/5 tries fails at 1600x1200 with 'select timeout'
+09:44 < jtanx> probably because it can't buffer that fast or something
+09:45 < jtanx> but definitely to run both cameras at once (or at least have them connected), you require an external power source, either for the beaglebone or for the usb hub
+09:47 < jtanx> yep
+09:47 < jtanx> if you do
+09:47 < jtanx> modprobe uvcvideo nodrop=1
+09:47 < jtanx> It will only display part of the image
+09:47 < jtanx> probably because it hasn't filled the buffer yet
+09:48 < jtanx> but if you load uvcvideo with normal settings
+09:48 < jtanx> it either displays the full image, or no image at all
+09:48 < jtanx> the problem is, I don't know how you detect this in opencv
