In general the response is "there is no generic way", the best that
you can achieve right now is to convert to a cattable format (mpeg,
rawvideo) and physically cat or use the concat protocol.

Logical join is not yet possible, although there is a gsoc task
concerning this (can't say about the status of the task itself).
