Hello,
i have a sanyo cg10 camcorder, i've tried to connect it to my pc using
it "pc camera" mode, it is recognized as uvc device but it is not
working. With vlc i see a green background, with luvcview:
$ luvcview -d /dev/video1
luvcview 0.2.6
SDL information:
Video driver: x11
A window manager is available
Device information:
Device path: /dev/video1
Stream settings:
Frame format: MJPG
Unable to set format: Input/output error
Init v4L2 failed !! exit fatal
Do you get any additional message printed to the kernel log when this
happens ? If not, please raise the driver trace level with
echo 0xffff> /sys/modules/uvcvideo/parameters/trace
and run luvcview again. The driver should then print additional debug
information.
well, i've found that it's working fine out the box, it's actually a
call to luvcview -L -d /dev/video1 that breaks it.
I'm very surprised by that. luvcview -L doesn't modify the hardware state.
Maybe only the first stream attempt succeeds ? Could you try running luvcview
-d /dev/Video1 multiple times in a row ?
You are right, the first time luvcview -d /dev/video1 works fine, the
second it does not.
