recorderCaptureVideo results in blank video

[GoogleCodeExporter]

What device(s) are you experiencing the problem on?

Samsung Captivate

What firmware version are you running on the device?

2.1

What steps will reproduce the problem?
1. use recorderCaptureVideo in a python script
2. ???
3. don't profit?

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

The expected output was a video saved in the location I passed into the 
function.  The file shows up once recording is finished, but it has no video, 
only audio.

What version of the product are you using? On what operating system?

The latest SL4A release _r2, I believe and Python 2.6.2.  Android 2.1 is the OS.

Please provide any additional information below.

Here's the script:

import android
droid = android.Android()
droid.recorderCaptureVideo("sdcard/videos/testvid.3gp", 5, 0)

I forgot to mention that cameraCapturePicture and 
startInteractiveVideoRecording both work just fine.

On my T-Mobile Touch G2 (aka HTC Hero) startInteractiveVideoRecording ignores 
the path argument completely (it records to \100MEDIA\VIDEOnnnn.g3p), 
cameraCapturePicture honores the path, but produces a completely black 1024x768 
picture. cameraInteractiveCapturePicture works, sort of, but is fixed to a 
640x480 (i.e. low) resulution. 

(SL4A V4, Python 2.6.2)
