After upgrading my macbook to Yosemite, I have been getting the following error whenever I launch an android emulator. I've tried all combinations of settings, but all report the same error. Any attempt to launch the built in camera app, or use the camera in my own app produces a crash. Below is the error I get when the emulator launches. Running the emulator with additional debug flags did not produce any additional useful info.
emulator: ERROR: Unrecognized pixel format 'v024'
emulator: ERROR: Pixel format 'v024' reported by the camera device is unsupported
This is an example of one of my emulator configurations:
Name: Nexus_5_API_21

The webcam works fine for other applications like photobooth or facetime.
Any ideas for how I might be able to resolve this error are greatly appreciated.
I had the same error. I fixed it by opening the Photo Booth app and then restarted the AVD while having Photo Booth in the background.
