These tags describe the product and quicktime library version respectively.
Originate from Adobe Premier, but some other products use them.

This comment was added in e309128f, in 2002, and has been brought
along since then more or less unmodified.

The first point of the todo was implemented in dbf30963 in 2006,
the second one is not relevant to rtpdec.c (brought along from
rtp.c in 8eb793c4 in 2008) but would be more relevant to the
rtp muxer, although it isn't a good idea anyway.
