[Ffmpeg-devel] Image formats missing?

Hi,

I'm trying to turn a bunch of jpegs into an AVI movie.

I've compiled the latest svn ffmpeg on Windows following the
guidelines of generating a Visual C++ compatible version:
http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC26
I'm using MINGW and MSYS latest versions and all compiled ok.

However aside from the already discussed .dll.xxx versioning
problems, there appears to be only GIF support in ffmpeg. I
noticed that the code for the image formats is commented
out in "libavformat/allformats.h and .cxx" by a #if 0 block.

I read most of the docs and faq and compatibility notes
but don't see anything about how I get sgi, png, jpeg, or
tiff support added to the "configure" script anywhere - and
beside it looks like the current #if 0 block will stop this
anyway.

Thanks for any pointers. I have versions of jpeg, png, libz
and tiff compiled up separately.

Cheers,

Colin.
