USB Camera issue with Android 2.3.4 Devkit 2.1

Hi Vinayaka,

For USB camera, kindly go to the function CameraHardware:CameraHardware() - CameraHardware.cpp file..

And mkae the version=0 after check of KERNEL version....

1. Idea here is to use standart camera framework for USB camera  and use a media framework for other cameras...

2. So I would advise make the version as zero, so that it will take standard path

I hope this will solve your problem.

Satish,

Thanks for the input. I tried this and no success with this change as well. I had removed some of the prints, so unable to see is this crossed the above error or not. I will try that and update you on exactly where it is giving error (I mean same place mentioned above or not). Mean time can you give some more inputs on this? I want camera to be up on Gingerbread or ICS. But I don't want to try on both - all experiment I can do it only one (I mean GB or ICS). If you have any suggestion please give it.

I have connected the USB (logitech) camera through a USB hub (external powered), even tried by connecting directly but the result was same earlier, but I have not tried with your suggested change.

Hi Vinayaka,

1. As I mentioned earlier, you have to take normal V4L2 path for USB camera not the media framerwork path.

2. After doing the changes suggessted by me kindly post both kernel logs ( dmesg) and android logs ( logcat) for more analysis

Satish,

I have attached both the logcat and kernel messages with this post. Please note that I have copied the log only after connecting the USB camera to the board.

Some of the prints in the kernel are added by me to find the problem location.

Hi Vinayaka,

Your logcat file is not opening.. Could you resend the same. ?

Satish,

Please find more detailed log cat & dmesg attached with this post. In this dmesg some of my debug prints have been removed

Please help me in resolving this issue. Is there a way to debug this issue using CCSv5 (or which forum is best for CCSv5 related question)?

Satish,

Any update on this?

Hello,

I'm using a USB camera with Android ICS, and it works fine with an specific App, but I need to set the webcam as default for all the apps. I mean that each one of the apps uses the USB camera.

¿Is it posible to do that in the script you mentioned?, I already make some changes and the camera works fine, but with some apps that just activate rear cameras it didn't work.

Can you help me please!!

I attache an image of the webcam working on the beagleboard-xm with Android ICS.

Hello!!

I have a question, the USB camera works with an specific app or as default for all the apps?

Thanks for the answer, I think I can help you to modify Android to get USB cameras working, but the issue is that the USB camera doesn't not work with all the apps.
