(FFmpeg README is listed below) ffmpeg4android is a “source” project for Android NDK, which contains latest FFmpeg modules (without bins), and ANDROID-USE-ONLY libraries compiled with all decoders and x264/aac encoders.
NOTICE: If what you need, are “how to use FFmpeg” rather than “how to compile FFmpeg” or “how FFmpeg works”, PLEASE goto FFmpegAdapter directly.
Please make sure, before you follow “How to xxx” below, you already knew what’s
environment-variable and similar basic technologies.
##How to use
- Download Android NDK
- Put the whole
ffmpeg-x.x.x/*folder (actually, only
ffmpeg-x.x.x/android/*is enough.) under
- Add reference
$(call import-module, ffmpeg4android/android/arm)into
Android.mkof your project with NDK.
- Now ndk-build should work. Tada~
##How to compile shared libraries (DEFAULT)
- Add path of ndk11 as environment variable :
$NDK_HOME(Will upgrade to ndk16 soon.)
- If you want to compile with x264, you need x264android at first. Then add x264 path as environment variable :
- Now you can run
./build.sh FFMPEG_CODES_FOLDERto compile. Tada~
##How to compile static libraries (BE CARE : LGPL limitation)
- Follow step 1 and 2 of “How to compile (shared libraries)”
- Now you can run
build.sh FFMPEG_CODES_FOLDERto compile static libraries. Tada~
- One more thing, modify
PREBUILT_SHARED_LIBRARY; And use
- Now the
all decodersbut only
aac and x264 encoders, if you need more, please modify it and re-compile. BTW, per X264, please follow GPL license.
ffmpeg-x.x) contains latest build (newer than
ffmpeg-2.4but not stable), be care.
- Codes newer than
ffmpeg 2.4, use
Android_newer.mk; otherwise, use
##Environment Android NDK only.
##License Should be same as FFmpeg…
