ogg dirac granulepos in oggz tools
...word. If we assume it is the higher word, i believe the granulerate would
need to be 2*(1<<9)*fps_n/fps_d; in order to allow dumb tools to get things
vaguely right.
Ie, if you were to perform a remux by:
foreach logical_stream s:
foreach page with GP64 != 0xffff_ffff_ffff_ffff:
page.muxing_time <- granule_rate * page.GP64
output_order <- sort_and_interleave (all logical_streams) using x.muxing_time
That would work for say dirac and vorbis i think and end up with
a reasonable ordering. Unfortunately, that doesn't work for the theora
granule-shift method, since mapping GP64<...
