Display two videos together then output as a merged video on a single screen

Question

This question may sound a little bit complex or ambiguous, but I'll try to make it as clear as I can. I have done lots of Googling and spent lots of time but didn't find anything relevant for windows.

I want to play two videos on a single screen. One as full screen in background and one on top of it in a small window or small width/height in the right corner. Then I want an output which consists of both videos playing together on a single screen.

So basically one video overlays another and then I want that streamed as output so the user can play that stream later.

I am not asking you to write the whole code, just tell me what to do or how to do it or which tool or third party SDK I have to use to make it happen.

update: Tried a lots of solution.

1.Xuggler- doesn't support Android.

2.JavaCV or JJMPEG- not able to find any tutorial which suggested how to do it?

Now looking for FFMPEG- searched for a long time but not able to find any tutorial which suggest the coding way to do it. I found command line way to how to fix it. So can anyone suggest or point the tutorial of FFMPEG or tell any other way to

Answer 1

I would start with JavaCV. It's quite good and flexible. It should allow you to grab frames, composite them and write them back to a file. Use FFmpegFrameGrabber and Recorder classes. The composition can be done manually.

The rest of the answer depends on few things:

• do you want to read from a file/mem/url?
• do you want to save to a file/mem/url?
• do you need realtime processing?
• do you need something more than simple picture-in-picture?
