[android help] Why CamcorderProfiles doesn't define the whole quality in android source code?

As we know , android provide the CamcorderProfile class in frameworks/base/media/java/android/media/CamcorderProfiles.java and the quality levels.

The following data is from android SDK.

1. int QUALITY_1080P Quality level corresponding to the 1080p (1920 x 1080) resolution.


2. int QUALITY_480P Quality level corresponding to the 480p (720 x 480) resolution.


3. int QUALITY_720P Quality level corresponding to the 720p (1280 x 720) resolution.


4. int QUALITY_CIF Quality level corresponding to the cif (352 x 288) resolution.


5. int QUALITY_HIGH Quality level corresponding to the highest available resolution.


6. int QUALITY_LOW Quality level corresponding to the lowest available resolution.


7. int QUALITY_QCIF Quality level corresponding to the qcif (176 x 144) resolution.


8. int QUALITY_QVGA Quality level corresponding to the QVGA (320x240) resolution.

There are eight levels.

The definition of the levels is in frameworks/av/media/libmedia/MediaProfiles.cpp . But I can only find little implemetion about createDefaultCamcorder action.

Such as:

/static/ MediaProfiles::CamcorderProfile* MediaProfiles::createDefaultCamcorderQcifProfile(camcorder_quality quality){}

/static/ MediaProfiles::CamcorderProfile* MediaProfiles::createDefaultCamcorderCifProfile(camcorder_quality quality){}

There are only two levels . So I want to know , why google don't implement the whole 8 levels? Or I had missed something ?

I am using Android 4.1.

Thanks.
