Compiling from SVN
------------------
If you donwloaded ffmpeg2theora from svn you have
need automake 1.6 or later to build the configure script.
To do this run ./autogen.sh
Then build as you would from a tarball.

Compiling from tarball:
-----------------------
you need
- the latest version of libtheora <http://downloads.xiph.org/releases/theora/>
- ffmpeg-trunk <http://ffmpeg.sf.net> by running ./get_ffmpeg_svn.sh
  (this script downloads current ffmpeg trunk, runs an appropriate
  configure and builds ffmpeg)

if you did not install ffmpeg but want to staticly link it
(recomended by ffmpeg developers) update PKG_CONFIG_PATH to
point to your ffmpeg source:

 export PKG_CONFIG_PATH=/path/to/ffmpeg_src:$PKG_CONFIG_PATH

now you can build ffmpeg2theora:
./configure
make

Installation
------------

make install

Unless you specify a different --prefix option to ./configure, you will
need root privileges for this, ie.:

sudo make install

Compiling on windows using mingw32:
---------------------------------
you have to compile libvorbis, libogg, libtheora
configure ffmpeg like this:
./configure --disable-encoder --enable-libogg --enable-vorbis --enable-theora \
 --enable-pp --enable-a52  --enable-gpl


vhook suppport
--------------

right now vhooks only work if you install ffmpeg and use 
the installed shared libs. otherwise one gets errors like this:
 undefined symbol: av_read_frame
this is a known limitation of vhooks in ffmpeg.
