Include in cordova project

[gen-failure]

Hi,

I tried to include the library to cordova project, but it's failing on this error :

E/FFmpegMediaMetadataRetriever(20120): FFmpegMediaMetadataRetriever libraries not found. Did you forget to add them to your libs folder?
W/dalvikvm(20120): Exception Ljava/lang/UnsatisfiedLinkError; thrown while initializing Lwseemann/media/FFmpegMediaMetadataRetriever;
W/System.err(20120): java.lang.UnsatisfiedLinkError

I tried to compile by myself and printed out the list of browsed directories

When I open .apk file the libs directory is present.

I will be very grateful for any help

[wseemann]

Can you send along an APK or the app source code?

[gen-failure]

I sent you apk file

I know that cordova has it's own building mechanism based on ant, so maybe some attribute is simply missing.

[gen-failure]

This actually helped me and it's not cordova related issue, maybe it will help others as well

I found the solution, it's still dirty, but works

100 /FIXME
101 if (!foundLibs) {
102 Log.e(TAG, TAG + " libraries not found. Did you forget to add them to your libs folder?");
103 throw new UnsatisfiedLinkError();
104 }
105
106 for (int i = 0; i < JNI_LIBRARIES.length; i++) {
107 System.load(path.toString() + JNI_LIBRARIES[i]);
108 }/
109 $
110 System.loadLibrary("avutil");
111 System.loadLibrary("swscale");
112 System.loadLibrary("avcodec");
113 System.loadLibrary("avformat");
114 System.loadLibrary("ffmpeg_mediametadataretriever_jni");
11
116 native_init();
117 }

Back when I used to compile FFmpeg with a soname prefix I need to load each library using the explicit path. Since I no longer use the prefix System.loadLibrary(...) seems to work fine. I've modified the code to use the proposed approach. Thank you for the bug report.

[gen-failure]

actually, it would be cool to have access to full ffmpeg binary but "/data/data" is probably not reliable way to reach it :)

[wseemann]

There are other projects that can build that binary (https://github.com/guardianproject/android-ffmpeg). A full binary wouldn't really make sense for this library so I won't provide one.
