Both. The helix client handles most of the work, but there
are specific parts of the process that are the
responsibility
of the fileformat plugin.
Since the fileformat plugin is the plugin with the
datatype-specific knowledge of how to parse a file, then
it is the plugin that knows how much of a file can
be played, given a certain amount of the file is
downloaded.
Therefore, most fileformats support the
IHXMediaBytesToMediaDur interface. The
ConvertFileOffsetToDur
method of this interface passes in a fileoffset and expects
a duration to be returned.

Fileformats should implement IHXMediaBytesToMediaDur.
