[Chromebooks] nabil2000:
again revisiting Acer Iconia W700 hybrid tablet...

My trick nocturne 71, eve 71 (on ATB v72) to get camera migration working no longer works for Acer Iconia W700 -

I think Google changes camera settings independently - camera from webstore still works -

However camera will never work with eve v72 & above -

though as said earlier, it works for MrChromebox flashed firmware Acer Chromebook C720P -

I wanted it to work for Acer Iconia W700 though as it's a hybrid tablet...

Camera again - got it to work as camera migration with cyan (with exton) on Acer CB C720P (Android 7.1.1)- but very laggy - so it might be a matter of memory resources -

will check on Acer W700 & report...

nope no dice -

I must add that this was with exton chromium OS (kernel 4.13.87) - not ATB v72 -

as summary, camera is not properly set up by googledevs to operate from Android container, I would say it is still in beta.

testing ...

$ sudo dmesg | grep uvcvideo -m 1 | awk -F '[()]' '{print $2}'

04f2:b335

$ sudo dmesg | grep uvcvideo -m 2 | awk -F '[()]' '{print $2}'

04f2:b335

04f2:b355

front & back camera of Acer Iconia W700

to be injected in

/etc/camera/camera_characteristics.conf

this courtesy of someone I will ack later if it works :)

camera

just mitigate manually by typing this in the shell: sudo dmesg | grep uvcvideo -m 1 | awk -F '[()]' '{print $2}'

copy the output, change any lowercase to uppercase

then remount / as rw, vim /etc/camera/camera_characteristics.conf

change the X part in camera0.module0.usb_vid_pid=XXXX:XXXX with the output of the above

and open Android settings > App > Camera > DISABLE

open chrome webstore, install Camera app.

I prefer like this:

chronos@localhost ~/Downloads $ sudo cp /etc/camera/camera_characteristics.conf ./.

chronos@localhost ~/Downloads $ ls

camera_characteristics.conf

modify, then copy back

chronos@localhost ~/Downloads $ sudo mount -o remount,rw /

$ chronos@localhost ~/Downloads sudo cp -f camera_characteristics.conf /etc/camera/camera_characteristics.conf

Tested tried for Acer Iconia W700 - did not work -

the camera from webstore does not work initially, used to work with older versions of eve like v71... on eve 73,

I removed camera from webstore - did the change as advised for front camera - disabled camera in Android settings, added to chrome webstore camera, does not work, so camera will not work either -

also there are 2 camera's back & front...

I will test try now with eve v71 as I just checked it still has webstore camera working... but how about the back camera?

this is the current content of

/etc/camera/camera_characteristics.conf

a similar section could be needed for the back camera?

it's not working for the front camera, will not work for the back camera - front is 04f2:b335 back is 04f2:b355 - I will reboot & see if it sticks - see my notes I posted in XDA forum

no dice on Acer Iconia W700 - only webstore with eve 71 - & none at all with eve 73...

I will stick to Acer Chromebook C720P :smirk:

mystery/peculiarity -

webstore camera mysteriously started working in Acer Iconia W700 with eve 73 after a reboot -

still no camera migration with above hack...
