A fusão não vai me ajudar aqui, porque o segundo vídeo é enviado pelo cliente e pode estar em muitos formatos e codecs diferentes (avi, mp4, mpeg, mpg, ts, mp4 ...) meu pensamento original era converter os dois vídeos para mp4 e se juntar a eles, mas que eu tenho problema com dois átomos MOOV e não é adequado para streaming Como mesclar 2 arquivos mp4 com 1 átomo?

Respostas:
Você precisa concatenar a introdução e o arquivo principal. A menos que eu tenha entendido mal sua exigência. Você pode usar o desmuxer; filtro; ou métodos de protocolo. Veja isso:
http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20concatenate%20%28join,%20merge%29%20media%20files
e isto:
http://ffmpeg.org/ffmpeg-filters.html#concat
Você diz que o segundo vídeo pode estar em uma variedade de formatos. Nesse caso, a recodificação é a única opção. O filtro parece funcionar nesses cenários.
