Do you support rubberband filter？

[xujingzhu123]

I want to execute the ffmpeg command in Android. I have introduced the Javacv ffmpeg library in the project, and I used the following method to call the ffmpeg command

String ffmpeg = Loader.load(org.bytedeco.ffmpeg.ffmpeg.class);
ProcessBuilder processBuilder = new ProcessBuilder(ffmpeg, "-i", "1.mp3");

but, I have found that this ffmpeg does not support rubberband filters. May I know what to do

I need to use this filter to change the pitch of the audio

Please update the cppbuild.sh file:

I'm not very clear about what you mean. Do I need to modify the parameters and compile them myself? Could you please provide me with detailed instructions

You can check this pull bytedeco/javacpp-presets#1427 for an example of that, do something like that.

I have made the necessary changes. If I need it urgently, what should I do

You can build it locally on your machine: https://github.com/bytedeco/javacpp-presets#build-instructions

I am not very familiar with the compilation of C++. Can you help me compile one that supports ruberband? Thank you very much

If you have a version of FFmpeg installed on your system that does what you want, you should be able to use it by compiling the presets with a command like mvn install -Djavacpp.cppbuild.skip
