OpenCore PVAuthor give a framework for mediarecorder. But for still
Image Capture is another framework in Android.
Now
1. Voice Recorder (use PVAuthor)
2. Still Image Capture (use Android Camera framework)
3. Video Recorder (There isn't in android)
What is the plan about Camera and MediaRecorder?
Does still image capture will be integrated in PVAuthor ?
They are much same point , such as the preview funtion.
Video recorder is now in the cupcake branch and will be merged to main
in the next few weeks. The mediarecorder takes a Camera object, or
creates one if the application doesn't supply one. The media recorder
service and the camera service are in the same process, so there is no
IPC overhead.

I don't think you are looking at cupcake branch. MediaRecorder has a
binder interface. It is not based on PVAuthor. Instead, like
MediaPlayer it is an abstraction layer so that another media framework
can be used if desired.

I know MediaRecorder is abstraction layer .
Whar is the final Implementation ,
Are they like this :
1. SoundRecorder is based on PVAuthor
2. Camera is not based PVAuthor
3. VideoRecorer will not be based on PVAuthor.
Do we have plan to using unify Implementation such as PVAuthor,
But it seem both PVAuthor and MediaRecorder abstraction layer are not
defined the still image capture intercace.

Thanks .
I think the Widget for Camera and VideoView may need consider more
for using HW overlay Surface.
For Preview case , It need do more consider than MediaPlayer. Ex, Add
UI emelent on the top of privew, so the WIdget Class need take
consider the layers management and color key.
Just like we discussed before.
