AVI and Matroska. If by MPEG-4 video, you mean AVC/H.264, then I
wouldn't recommend AVI.
Decent software players should have no problems with this, but very few
hardware players would support this combination, even if the codecs and
container are supported in other combinations.

Not sure if Matroska can specify an offset, but I know MP4 and MPEG-TS can.
