Hi, I found you have used ffmpeg to mix the audio and video, Is the C source code open? Where can I get it?

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.

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

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.

prepareAVFormatContext -> https://github.com/OpenWatch/FFmpegWrapper-Android/blob/master/FFmpegWrapper/jni/FFmpegWrapper.c#L302
setAVOptions -> https://github.com/OpenWatch/FFmpegWrapper-Android/blob/master/FFmpegWrapper/jni/FFmpegWrapper.c#L345
writeAVPacketFromEncodedData -> https://github.com/OpenWatch/FFmpegWrapper-Android/blob/master/FFmpegWrapper/jni/FFmpegWrapper.c#L374
finalizeAVFormatContext -> https://github.com/OpenWatch/FFmpegWrapper-Android/blob/master/FFmpegWrapper/jni/FFmpegWrapper.c#L432
