Re: building libtheora 1.0 on win64

Hello there,

if I remember correctly Theora 1.0 used the old VP3 encoder mostly
unchanged, perhaps even with the original header values.

Thankfully you can force Theroa 1.1/1.2 into a VP3 compatible mode, use
http://www.theora.org/doc/libtheora-1.1/theoraenc_8h.html#a382d685a39a34d8e6ba76b00d804efd8
with
http://www.theora.org/doc/libtheora-1.1/group__encfuncs.html#ga3a427f6514dfdc01ea72172c469d51d9

This of course means you need to (very) slightly modify your encoding
setup code.
