Does a SMIL file having multiple mpeg-4 files being played sequentially or in
parallel, eventually get converted into 1 mp4 file during playback ? Given
below is one such SMIL file, which plays 2 video clips in parallel, when
played in a media player.

It has been observed that while using IBMToolkitForMpeg420061204 tool the
following  conversions resulted

SMIL -> XMT-0 ->(using XMTBatch.exe) .mp4 -> (using MP4BOX tool) BIFS (Had 2
streams for audio and video, 1 for each clip.)   

 It this always true and takes place internally, when a SMIL file is being
played by media players ?
