[WIP] - ICS Camera HAL for 2.6 kernel

rapmv78 · Jan 4, 2012

I have re-written the ICS camera HAL module to be a thin wrapper for the gingerbread libcamera.so and hence it will only work with the 2.6 kernel. The advantage is that getting to gingerbread level functionality should be quick

Creating a new thread because there is a slight chance that this will work for all qualcomm devices with existing libcamera.so files (with slight mods ofcourse

)

http://www.mediafire.com/download.php?wjf035mz2vzunw4

Here is a zip file which contains the new camera HAL module. README file accompanying it has instructions on the locations for the files. If you already have the previous version of camera HAL working, all you have to do is replace camera.qsd8k.so and libcamera.so with the ones in the zip file.

What works:
1) Preview works.
2) Taking a picture works pretty well.
3) Size of picture is no longer huge.
4) Software zoom works.
5) Most of the other knobs like focus, file size etc. seemed to work as well in my testing.
6) Pretty stable as far as I can see

Not working yet:
Video and other fancy stuff.

If people have requests for other qualcomm devices after having tried the HAL included in the zip file, kindly include the following information.
1) logcat from having used the HAL module.
2) build.prop
3) libcamera.so from gingerbread ROM for the device.
4) liboemcamera.so from gingerbread ROM.

Currently known to work on the following devices:
1) Nexus One.
2) HTC Desire
3) HTC HD2

Enjoy and thanks for all the feedback.

Working Panorama mode

Flashable zip file (should work with texasice's ROMs)

Known issues:
Sometimes screen has some garbage while in Panorama mode viewfinder. Quitting completely from the app and restart or invoking Gallery from inside the app and returning back to camera app should mostly fix it.

Video enabled version:

Fastboot compatible images compiled from evervolv base:

Your upload doesn't include a HAL, and from your instructions I am not sure if you are implying to use the HAL and the GB libcamera and liboemcamera, or the ones included.

please show me what i have to type in adb to push these files? (sorry i'm noob)

is camera.qsd8k.so not included?
sorry for my english..

rapmv78 · Jan 4, 2012

Sorry wrong link. Now updated. Please re-download. And yes the files need to pushed through adb.

tonyeva · Jan 4, 2012

One step closer!
Thank you!

Link fixed. The files included in the zip are the ones to be used. The generic libs part is only for people with non nexus one devices and would want help enabling camera on them. Hope this clarifies better.

Is the code specific to qsd8 or just a generic wrapper function? On most "newer" devices you are looking at msm7x30, but generic qsd8 code, much like the gralloc, would still work with a rename.

if i have installed the previous version, is it right what i have to type in adb?

Code:

adb remount
adb push libcamera.so /system/lib/libcamera.so
adb push camera.qsd8k.so /system/lib/hw/camera.qsd8k.so
adb reboot bootloader
fastboot flash boot boot-new.img
fastboot reboot

please help, i don't know what to do..
thanks..

If you have previously working camera, you can skip flashing the boot-new.img file. It is there for people who do not have existing ics camera hal. Rest looks fine to me.

It is just a wrapper, but is dynamically linked with the libcamera.so file. So, if kernel change does not change structs and constants, things will work fine with a rename as you suggest. Otherwise it will not.

Maybe you should ask @charnsingh_online help for video, as he already works on 720p for N1

So what were the kernel changes?

There are none in this hal, that is why it works. What I was intending to say was that if MSMx30 kernel uses different size structs/constants it will not work.

That is why I asked if it was generic code or specialized to qsd8. If the kernel code was not edited, that will be irrelevant because the source is not built (at least not by anyone other than CAF) using an inline kernel.

The hal code itself is generic, but it depends on libcamera.so, which inturn depends on kernel structs and constants to match the running kernel for successful control ioctls/pmem etc.

Can confirm this works on HTC Desire exactly as mentioned in OP.

I tried it with (Texas)Ice ICS ROM and network not work. Failed to load driver! Need flash another kernel?
