How to use the data which received from callback onFrameChanged() to feed to ffmpeg to generate a h.264 video?
Is this possible? Any suggestions are welcome. Thanks.

I havent used ffmeg but it should be simple to implement.

If you create a demo on this I can add it to the examples :)

OK, I will create a demo.

Are there any improvements in using ffmpeg? A demo would have been quite helpful.
I'm wondering how to save in video format using this library. I run the examples, and I get the screenshots. But my goal is to capture these data as video files without saving them as images. Could you please show me a way? @xfirefly @smasherprog
