Locally compiled FFmpeg

clj-media also supports using a locally compiled FFmpeg build.

Example compilation:

git clone https://github.com/FFmpeg/FFmpeg.git
cd FFmpeg
./configure  --extra-ldflags='-Wl,-ld_classic' --enable-shared --prefix=`pwd`/build
make
make install

To use the local build:

1. Add the libraries to the JNA library path
2. Exclude the ffmpeg dependency, org.bytedeco/ffmpeg-platform

Example alias:

{:aliases
 {:local-ffmpeg
  {:jvm-opts ["-Djna.library.path=/path/to/FFmpeg/build/lib"]
   :deps {com.phronemophobic/clj-media {:mvn/version "2.3"
                                        :exclusions [org.bytedeco/ffmpeg-platform]}}}}}
