I'm developing a video chat like application for Android. Can I record and play video on the screen at the same time? Can I compose the videos over one another (FaceTime style) or do the y have to be side by side? Can I use the MediaPlayer and MediaRecorder classes or do I have to use lower level APIs?
Avner,
To answer to your question bit wise
1> Can I record and play video on the screen at the same time? Ans : yes you can.
2> Can I compose the videos over one another (FaceTime style) or do the y have to be side by side?
Ans: You can not have PIP(Picture in picture) (http://stackoverflow.com/questions/4521674/handling-two-surfaceviews)
you can go for a side by side option.
3> Can I use the MediaPlayer and MediaRecorder classes or do I have to use lower level APIs? ans: yes you can use these.
