There is no way you can achieve this with current Android API.

You need to encode the frames using an encoder in C++ and pass your bitmaps to the encoder via JNI. You can start with MoboPlayer's ffmpeg port. You may find the download link to their ffmpeg port at the bottom of this page

If you have the image sequence in Bitmaps, you can access the Bitmap's buffer from JNI using the AndroidBitmap_* methods and pass it on to ffmpeg for encoding
