Installation of libtheora

Install libtheora by running the following commands: 

sed -i 's/png_\(sizeof\)/\1/g' examples/png2theora.c &&
./configure --prefix=/usr &&
make

If you wish to run the tests, issue: make check.

Now, as the root user: 

make install

If you built the examples and wish to install them (so that you can hack on theora): 

cd examples/.libs &&
for E in *; do
install -v -m755 $E /usr/bin/theora_${E}; done

Command Explanations

sed -i 's/png_\(sizeof\)/\1/g' examples/png2theora.c: This sed fixes build with libpng 1.6.

--disable-static: This switch prevents building static libraries.
