Huh, it's 'review pending patches' day :-)
hverkuil: it's 'pull requests' day for me :-)
is this the appropriate channel for questions about the uvcvideo module?
Romme: it is
i'm having this intermittent error:  uvcvideo: Failed to set UVC commit control : -32 (exp. 26)
when this happens the camera doesn't start streaming
and i also get this message all the time but it's not fatal: "uvcvideo: Failed to query (GET_DEF) UVC control 1 on unit 2: -110 (exp. 2)."
what camera is that ?
a chinese one
one of these guys http://www.elpcctv.com/usb-cameras-c-85.html
can you send me the output of 'lsusb -v' (preferably running as root) for the camera ?
pretty expensive stuff, $100 a piece
it will be rather long, you can send it by e-mail
building usbutils...
gentoo ?
i got a few "can't get debug descriptor: Resource temporarily unavailable" in stderr when running lsusb
buildroot on rpi
i also got "failed to resubmit video URB" in dmesg last time
now trying to reproduce a situation in which the camera doesn't start
ah, rpi
that's most likely the issue
the rpi usb host controller is crap
i'll revert to linux 4.1 and this most likely will fix my issue
mainline 4.1 ?
raspberry pi foundation 4.1
i'm on 4.4 from the foundation right now
I doubt it will work better
maybe if you're lucky
it helped
the errors are no more
pinchartl: what's the host on Rpi?
headless: its a broadcom USB controller
ah
not sure it's supported upstream
no it's not
is it possible to "suspend" a uvc webcam?
what do you mean by suspend ?
like on usb flash drives, suspending them (or whatever) turn off the LED
UVC devices, like all USB devices, should support USB suspend
hverkuil: I decided to add 16-bit media bus codes and 16-bit pixelformats as well to the set. Still waiting for confirmation on the 10-bit packed format fix...
sailus: OK
what is the script called again that generates you a .config for your current system?
hverkuil: hi! did you find time to run stability tests on your tw686x?
ezequielg: no. I did some tests some time ago, but it wasn't long enough (several hours only, I think).
hverkuil: i'm still wondering about that damn memcpy mode...
hverkuil: we never got the board manufacturer to look into it, and i was unable to purchase a different card.
hverkuil: I am seeing kernel page execptions in v4l2_release() path if unbind driver while video device is in use. I have a fix for it. Should I send RFC so we can dicuss
shuah: RFC is fine.
okay thanks
ezequielg: how different are the fps vaues for 50Hz
larsc: diet_kconfig
(for an optimized one that will disable all other drivers)
make oldconfig if all you want is to repeat the same config stuff on a newer Kernel
