libav/ffmpeg: Compile/Link 2 versions of native FFMPEGMediaPlayer methods FFMPEGNatives -> FFMPEGv08Natives + FFMPEGv09Natives
Enables FFMPEGMediaPlayer to work w/ either ffmpeg/libav version 8 or 9 w/ same JOGL binary Same C source code is compiled against 1: version 0.8 FFMPEGv08Natives lavc53.lavf53.lavu51 2: version 0.9 FFMPEGv09Natives lavc54.lavf54.lavu52.lavr01 FFMPEGv08Natives and FFMPEGv09Natives implements FFMPEGNatives, native C code uses CPP '##' macro concatenation to produce unique function names. To enable 'cpp' to find the libav* header files matching the desired version, we have placed them in the c-file's folder, issued '#include "path/file.h" and added symbolic links to allow finding same module and 'sister modules': ls -l libavformat/ .. lrwxrwxrwx 1 sven sven 13 Aug 26 12:56 libavcodec -> ../libavcodec lrwxrwxrwx 1 sven sven 14 Aug 26 12:56 libavformat -> ../libavformat lrwxrwxrwx 1 sven sven 12 Aug 26 12:57 libavutil -> ../libavutil .. At static init FFMPEGDynamicLibraryBundleInfo, determines the runtime version and instantiates the matching FFMPEGNatives, or null if non matches. FFMPEGMediaPlayer still compares the compile-time and runtime versions. FFMPEGMediaPlayer passes it's own instance to FFMPEGNatives for callbacks.
