x86 lollipop reference camera HAL error on gralloc dequeue buffer due to invalid format (-22)

[mepi...@gmail.com]

Hi,

I'm trying to run Camera HAL3 reference code in /hardware/libhardware/module/camera to see actual function call flows of new api with logs.
While I'm testing the code, I faced below errors:

------------------------------

With some test code I could see failure comes from the image format 0x22 which is HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED (= CAMERA2_HAL_PIXEL_FORMAT_OPAQUE).
Does drm-gralloc support this format ?
If it does, is there anything I need to configure for camera HAL3 ?


Several things about my development environment:
- I don't have physical camera HW since I just want to see the code flow of new camera API.
- I have my desktop running Android-x86-Lollipop with nVidia graphics card. (NVS 310)

Below are things I've done so far:
- I changed graphics card to see if it's related, none of them works even virtual box.
- I tested nomodeset option for booting, but it's not working.
- I hard-coded the format to HAL_PIXEL_FORMAT_RGBA_8888. It passed the error during dequeuing, but another error comes on registerBuffer().

Thanks,
Chris Kwon.

>>>Does drm-gralloc support this format ?

drm_gralloc do not have support for format 34. You can make it RGB_565 and try.

You may also need to add support for format 34 in mesa
