How can I record video on a Pinephone?

[Kevin Kofler]

I did find that device references needed to be changed to from "device4" to "device1". (The devices 0, 1, and 2 exist. Only #1 had the required entries.)

Looks like the device number depends from phone to phone, depending possible on the distro, the kernel version, and/or the hardware revision. My PinePhone now has the accelerometer on device2. Used to be device3, which does not even exist now.

I guess we should just use a wildcard, as in:

Code:

CUR_X=$(cat /sys/bus/iio/devices/iio\:device*/in_accel_x_raw)
CUR_Y=$(cat /sys/bus/iio/devices/iio\:device*/in_accel_y_raw)

then the shell will pick the correct sensor.

Code:

[mobian@mobian bin]$ ./record.sh test
portrait

**** Executing the following command:
**** media-ctl -d1 -l'"gc2145 4-003c":0->1:0[0],"ov5640 4-004c":0->1:0[1]'

Unable to parse link: Invalid argument (22)
[mobian@mobian bin]$

I guess the camera names are wrong. Try using 3-003c and 3-004c instead of 4-003c and 4-004c. For me, the ones with 3- are the correct ones, both back when I wrote the script and now. It looks like those names also depend on the hardware or distro, which is a problem, because the numeric IDs (5 and 7 in my case) are not stable either (e.g., I had them swapped at some point). Or print the topology with

Code:

media-ctl -d1 -p

and copy the names from there. That, or the hardcoded 1 for the sink is wrong, try the name "sun6i-csi" (including the quotes) instead.
