modify media_profiles.xml

[ispark]

Target:

i.mx6 Android 4.4.2 1.0.0~rc3

Kernel 3.0.35

Board: solid-run cubox-i som i1.

I uses i.mx6 with UVC camera and current configuration is like below.

V/CAM_VideoModule( 3280): mDesiredPreviewWidth=640. mDesiredPreviewHeight=480

I/FslCameraHAL( 2299): Width * Height 640 x 480 format 0x56595559, fps: 30

Now I wanna change resolution to below.

I/FslCameraHAL( 2299): SupportedPictureSizes: 1280 x 720

Android builder echos below process for default configuration.

target Prebuilt: media_profiles.xml (out/target/product/cuboxi/obj/ETC/media_profiles.xml_intermediates/media_profiles.xml)

Install: out/target/product/cuboxi/system/etc/media_profiles.xml

I want to change out/target/product/cuboxi/system/etc/media_profiles.xml

Where should I modify original media_profiles.xml?

:smileyhappy: , OK!

When checking log data, below value is changed.

Initial value:

I/FslCameraHAL( 2299): mMaxWidth:1280, mMaxHeight:720

changed value;

I/FslCameraHAL( 2298): mMaxWidth:960, mMaxHeight:544

But below value are still not changed:

V/CAM_VideoModule( 3445): mDesiredPreviewWidth=640. mDesiredPreviewHeight=480

do you have any idea?

[ispark]

Dear Weidong,

One more thing, when I set below parameter manually, video broken.

width = 960; height =544;

and while finding some information, it should be upgraded to KK4.4.3.

Do you have any idea?

[ispark]

I upload new UvcDevice.cpp and tested.

but resolution is still remains to 640*480 like attached.

Would you please check what should I do?

belowis new log.

I've got source, thanks.

Hi ,

     You don't need to modify media_profile.xml, but camera HAL of UVC should be adjusted. you can try the attchment. I adjusted the HAL for you !

Regards,

Weidong

[ispark]

Thanks for your response, but i cant find attachment, would you please check again?

[weidong_sun]

UvcDeivice.cpp was attached again, check it please!

[ispark]

Hi Weidong, Does it possible to get by email?

ispark@megacast.co.kr

or any link should be OK.

[ispark]

Sorry but I cant find link or attachment for UvcDeivice.cpp .

would you please let me know where should I download?
