Capturing SurfaceView into video file based on google/grafika examples

I would like to load video from file, make some transformation on it and render it back into file. Said transformation is mainly two videos overlapping and shifting one of them in time. Grafika has some examples relevant to this issue. RecordFBOActivity.java contains some code for rendering video file from surface. I'm having trouble changing two things:

My only success so far was to load .mp4 file and add some basic seeking features to PlayMovieActivity.java.

In my reasearch I came across these examples, which are also using generated video. I didn't found them quite useful, because I couldn't swap this generated video with decoded one from file.

Is it posible to modify code of RecordFBOActivity.java so it can display video from file instead of generated animation?

You can try INDE Media for Mobile, tutorials are here: https://software.intel.com/en-us/articles/intel-inde-media-pack-for-android-tutorials

Sample code showing how to enable editing or make transformation is on github: https://github.com/INDExOS/media-for-mobile

It has transcoding\remuxing functionality in MediaComposer class and a possibility to edit or transform frames. Since it uses MediaCodec API inside encoding is done on GPU so is very battery friendly and works as fast as possible.
