First of all, it’s 9021 already. On Android, MediaCodec is total enough though. Try it.
(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 ndk-build
, environment-variable
and similar basic technologies.
##How to use
ffmpeg-x.x.x/*
folder (actually, only ffmpeg-x.x.x/android/*
is enough.) under $NDK_HOME/sources/ffmpeg4android/
$(call import-module, ffmpeg4android/android/arm)
into Android.mk
of your project with NDK.##How to compile shared libraries (DEFAULT)
$NDK_HOME
(Will upgrade to ndk16 soon.)$X264_HOME
./build.sh FFMPEG_CODES_FOLDER
to compile. Tada~
##How to compile static libraries (BE CARE : LGPL limitation)
--enable-static
instead of --disable-static
in build_android.sh
build.sh FFMPEG_CODES_FOLDER
to compile static libraries. Tada~
Android.mk
, use PREBUILT_STATIC_LIBRARY
instead of PREBUILT_SHARED_LIBRARY
; And use lib***.a
instead of lib***.so
##Notice
build_android.sh
includes all decoders
but only aac and x264 encoders
, if you need more, please modify it and re-compile. BTW, per X264, please follow GPL license.ffmpeg
folder (not ffmpeg-x.x
) contains latest build (newer than ffmpeg-2.4
but not stable), be care.ffmpeg 2.4
, use Android_newer.mk
; otherwise, use Android.mk
.##Environment Android NDK only.
##License Should be same as FFmpeg…
