I'm looking for an open-source video editing program that can combine 2 videos into one single video where both video are playing along each other side by side (see example here)

One video is made from my own set of images (export from powerpoint presentation) and has therefore no sound and speed can be adjusted if necessary

Any suggestions ?

Unfortunately, open source video editors are few and far between. Unlike most other common application types (like audio editors, video players, text editors, etc), the video editing application market has been largely untouched by the open source community. I don't know if you'll find what you're looking for if you limit yourself to strictly open-source software. – SpikeX Jan 18 '11 at 17:42

The merging behavior you describe is called Picture in Picture (PiP), or more specifically it's called Picture and Picture (PaP, P&P), commonly referred to as Picture by Picture (PbP).

For Linux, you could try use Cinelerra to create PIP videos.

For Windows, you are going to face a lot of trials/shareware so your best bet is professional software.

For programming your own solution, you might be able to use this OpenCV example.

Yeah, I passed along that one while searching and I thought I saw a tutorial for it. But didn't list it because it looks like a trial... – Tom Wijsman Jan 19 '11 at 13:58
