mp4parser version conflict (compressed video has no sound)

I am using these two libraries in my project:

https://github.com/HemendraGangwar/VideoTrimmingLikeWhatsapp https://github.com/fishwjy/VideoCompressor

Both libraries are imported locally to my project (i.e. copied them and added them to the project)

Both libraries work fine when used separately, but when I use them together I get some errors of type Program type already present which I solved by deleting the file isoparser-1.0.6.jar from the second library, because I noticed that the two libraries use the same library 'com.googlecode.mp4parser:isoparser' but with different versions: 1.1.21 for the first one and 1.0.6 for the second one.

When using only the old library, I get this code:

error: cannot find symbol class FileDataSourceViaHeapImpl

It is working now, but the problem the output video (after compression) does not have sound on it. How can I solve this?

Here is the code I am using for compressing the video (after trimming):

VideoController.getInstance().convertVideo(tmpFile.toString(), dstFile.toString(),
           VideoController.COMPRESS_QUALITY_MEDIUM, null);
