is it possible to concatenate RTSP sources and stream this?

[isync]

Hello,
I've got a list of separate RTSP stream sources, like rtsp://www.example.com/file1.mp4, rtsp://www.example.com/file2.mp4, rtsp://www.example.com/file3.mp4

Would it be possible to create a playlist of these rtsp files and then re-stream the result as one uninterrupted stream?
