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.

+ *
+ * @{
+ * Dictionaries are used for storing key:value pairs. To create
+ * an AVDictionary, simply pass an address of a NULL pointer to
+ * av_dict_set(). NULL can be used as an empty dictionary wherever
+ * a pointer to an AVDictionary is required.
+ * Use av_dict_get() to retrieve an entry or iterate over all
+ * entries and finally av_dict_free() to free the dictionary
+ * and all its contents.
+ *
+ * @code
+ * AVDictionary *d = NULL; // "create" an empty dictionary
+ * av_dict_set(&d, "foo", "bar", 0); // add an entry
+ *
+ * char *k = av_strdup("key"); // if your strings are already allocated,
+ * char *v = av_strdup("value"); // you can avoid copying them like this
+ * av_dict_set(&d, k, v, AV_DICT_DONT_STRDUP_KEY | AV_DICT_DONT_STRDUP_VAL);
+ *
+ * AVDictionaryEntry *t = NULL;
+ * while (t = av_dict_get(d, "", t, AV_DICT_IGNORE_SUFFIX)) {
+ * <....> // iterate over all entries in d
+ * }
+ *
