A second call to Camera.takePicture() crashes the mediaserver if Camera.Parameters.setRecordingHint() is true #639

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
On Glass, the MediaRecorder only works if the Camera Parameters has 
setRecordingHint(true). However, with this set, the camera can only take one 
picture. The second call to takePicture() crashes the mediaserver.

What steps will reproduce the problem?
1. Build a typical camera activity - SurfaceView, open the camera, etc.
2. After opening the camera, get its parameters, call .setRecordingHint(true) 
on the parameters, and then set those parameters back on the camera.
3. After calling startPreview() on the camera, call takePicture() with a JPEG 
callback.
4. Call startPreview in the JPEG callback, as normal, to be able to take 
another picture.
5. Call takePicture() again.

What is the expected output? What do you see instead?

A second successful call to takePicture() is expected. Instead, the mediaserver 
crashes.

The mediaserver crashes, and not always in the same place. Here's one of the 
stacktraces that appeared in logcat:

Note that the second call to takePicture() does not need to be at all near (in 
time) to the first call. In this example, the second takePicture() call 
happened 3 seconds after the first.

Hello,

Could you share a small source code or sample APK that we can use to reproduce? 
I've been using the described steps but can't make the crash happen.

Thanks!
Alain

Here's a simple app which reliably crashes the mediaserver. It shows a simple 
count in the lower right hand corner for the number of successful takePicture() 
calls.

In the CameraActivity, if you comment out the line 
"parameters.setRecordingHint(true)", you can take as many pictures as you want. 
If you leave it in, then the media server will crash the second time you 
depress the camera shutter.
