Why different codecs? Or rather, how many different codecs, and which
ones? What is the intent behind providing several of them?

BTW, while we're talking about codecs:

Libquicktime 0.9.* supports at least four hardcoded, plus jpeg and png
from those ubiquitous libraries. LQT 0.9.3 seems to have more hardcoded
ones, plus a lot of pluggable ones (that depend on libraries that people
don't always have)

A list of currently supported codecs is available this way in GF:

[#out quicktime file /dev/null, codec HELLLLLLP]

Here it answers:

error: ArgumentError: warning: unknown fourcc 'help' (["DIVX", "v410",
"yuv2", "mjpa", "yuv4", "raw3", "png ", "raw ", "jpeg", "RTJ0", "yv12",
"v308", "v408"])

I don't quite know how to make it easier without bypassing a lot of
structure. I'm trying to think of a standard way to query a "Format"
without creating an object for it. I mention all of this because while
telling Normand how to access that list, he misunderstood me and overwrote
a file he had to get back from a CD :-( which is why I say /dev/null now
and why I'm looking for a better way.
