Thanks yang,
Yes armv7, but I looked into it more over easter and it seems to be an odroid issue.
The kernel in there is ancient (3.10) and does not include this patch lkml.org/lkml/2013/5/24/440
Which would explain an error message i noticed in dmesg.
Recompiled the kernel with the patch and tried it out
Next I encountered this:
webcache.googleusercontent.com/search?q=...&client=firefox-b-ab but it seems to work with the value increased to 1M

I let captures run and got about 300 now before failing with:

The lines in the beginning appear through, even when I can successfully capture.
I'd say this is not a problem in the SDK but the odroid-kernel and I'll investigate further in that direction, maybe I can get a 4.x kernel up.


PS: On a sidenote an issue I had where captures shorter than 1000ms seconds would always fail in 16bit seems to have improved as well with the fixed kernel
