The author must have modified some codes to satisfy the application. This is the key.

No, the FFmpeg sources are unmodified. The JNI bridge is open source.

Where can I download the JNI bridge codes?

[chrisballinger]

https://github.com/Kickflip/kickflip-android-sdk/blob/master/sdk/src/main/java/net/openwatch/ffmpegwrapper/FFmpegWrapper.java

Cant seem to find the .c file, but it's somewhere.

[yulf]

Did the author release the C source code ? I can not find them.

The FFmpeg wrapper can be found here: https://github.com/OpenWatch/FFmpegWrapper-Android/tree/master/FFmpegWrapper/jni

But, if you want to make changes to that code, you have to build the library with ndk-build.sh

EDIT: the compiled and built .so library goes here: https://github.com/Kickflip/kickflip-android-sdk/tree/master/sdk/src/main/jniLibs

Pay attention to match library/architecture

[yulf]

In https://github.com/Kickflip/kickflip-android-sdk/blob/master/sdk/src/main/java/net/openwatch/ffmpegwrapper/FFmpegWrapper.java, there are functions as follow: public native void setAVOptions(AVOptions jOpts); public native void prepareAVFormatContext(String jOutputPath); public native void writeAVPacketFromEncodedData(ByteBuffer jData, int jIsVideo, int jOffset, int jSize, int jFlags, long jPts); public native void finalizeAVFormatContext();

But, In https://github.com/OpenWatch/FFmpegWrapper-Android/blob/master/FFmpegWrapper/jni/FFmpegWrapper.c, I can not find corresponding C implementations.
