[M4IF Technotes] Downloadable standard MPEG test sequences

[Ben Waggoner]

Olivier,
    So, there really isn't a .yuv file format, then?  Just a bunch of
mutually incompatible formats with the same extension, and no
programmatically way to discriminate between them.
    Well, in that case we should convert them all the the 2vuy QuickTime
files or whatever and make THAT the de facto standard.  The file format for
those is fully public, and obviously familiar to MPEG-4 folks.  And it would
remove ambiguity and vastly increase the number of tools that can use the
standard test sequences.
