Thank you for doing that work, Martin!
It looks very promising.
However, initialization of AudioVideoLib-Container-maku.1.mcz
runs into an error. This is because
AvihChunk initialize
is evaluated before
RIFFChunk initialize
was evaluated.
RIFFChunk initialize creates an IdentityDictionary that is needed for
AvihChunk initialize.
I think the problem here is that (as in change sets) there
is no way to control the sequence in which the class initializers
are called.
A quick fix would add a check in
RIFFChunk class>registerHandler:forType:
Greetings,
Boris
