I'm trying to develop an android app to extract frames from video, using VideoCapture in OpenCV. To interface ffmpeg onto OpenCV, I followed Roman10's tutorial and then downloaded the sample package that was provided by Roman10 and written by Stephen Dranger: https://github.com/roman10/android-ffmpeg-tutorial
When I build the project, it gives me a bunch of errors: Android NDK: Aborting. Stop. make: * [libavfilter/x86/af_volume.o] Error 127 recipe for target 'libavfilter/x86/af_volume.o' failed
Where should I start to troubleshoot this issue?
