Camera Support Thru Android

[tllim]

hopefully it works or there is a way to enable it to work.

Aside from any camera-related project like the one I'm planning to fulfil when I receive my boards, Pine64 runs Android and one of Android's basic apps is Skype. That said, If there is no UVC support then skyping will not be possible and that would be a major blow for many users, if not for all.

I am currently work with Remix OS folks and they will report UVC driver to next Remix OS release. Once work, we will follow up on Android build.

Good to know! Thanks for the feedback.

I'm sure you are going to make it. I have no experience with Android development but I'm quite sure it's easy for a developer to implement UVC driver to the Operating System itself.

Please do keep us updated.

Any progress on this? I take the silence as a negative response...

Progress is positive, the UVC source code already located and currently porting over to 64 bit version for Pine A64. Hopefully we will release in about two weeks time.

Oh great!  Was not expecting  positive news. Thanks

And as I have you here TL LIm, may I ask if the camera module finally arrived? May I also ask if RTC module and HDMI cables are available? If these are already available, then it's safe to assume that my order is about to be shipped or has been shipped already.

There is a library that should enable what you need, I am currently after the same thing, so I am right as I write downloading the source to build a rom that has UVC as an android native camera.

I am working on bringing up the camera module for pine64 which will open UVC webcams, I have it compiling and building and attempting to open /dev/video0, just need to test tonight when I am home, am working with Ayufan's branch of work so eventually it will be working on one of his builds.

@mikey0000 Any progress with USB based UVC webcams?

I'm playing with a Logitech HD Pro Webcam C920, which doesn't work nice on Android TV 7.0. I've tried different version, but I get the same log output.

$ dmesg
[   65.597979] uvcvideo: Found UVC 1.00 device HD Pro Webcam C920 (046d:082d)

When Skype accesses the camera, I get the following from logcat:

$ adb logcat HALCameraFactory:* VideoService:* V4L2CameraDevice:* *:S

Any help would be appreciated.

I've added the Tellybean "Test Camera" logcat. Here is snippet:
