theora - Oct 2012 - building libtheora 1.0 on win64

I have an old conferencing app that uses theora and I'm building it for
win64.

libthora 1.1 builds just fine, but libtheora 1.0 has errors related to
assembly code when building for x64.

I've tried using 1.1, but the video does not look right --  the clients all
generate their own first 3 packets instead of sending them over the network
since they assume they are all on the same version of libtheora.

I need to either initialize the 1.1 library using the 1.0 mode codebook, or
somehow get the 1.0 library to build for win64 under vs2008.

I've googled and seen reference to a patch for win64 builds, but it is not
in the http://downloads.xiph.org/releases/theora/libtheora-1.0.zip that I
just downloaded.

Help?

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.

Do or does anyone have a Xcode document to aid in the chore? Any guidelines?

There have been several requests, but no one has contributed one.

Start with the source lists in *_sources.mk and *_headers.mk, define
OPUS_VERSION and OPUS_BUILD in the preprocessor. That should get you
a working xcode build of the library.

Is that for Opus or Theora?
