Though my current ndk version is greater than r10e , but it is saying
build on Linux x86_64
ANDROID_NDK=/root/Android/Sdk/ndk-bundle/
IJK_NDK_REL=15.1.4119039
You need the NDKr10e or later
EDIT
I am trying to build ijkplayer , I am just following the build instruction when I tried to execute the ./compile-ffmpeg.sh all
I got this error.
