I am trying to compile ffmpeg for android armeabi devices.
I am following tutorial by roman10.net
His given build script builds ffmpeg for armv7-a devices. I want to build it for armeabi.
My ultimate aim is to run ffmpeg commands on android armeabi and armv7-a devices.
So I change the script's CPU part from
#arm v7vfpv3 CPU=armv7-a OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=vfpv3-d16 -marm -march=$CPU " PREFIX=./android/$CPU ADDITIONAL_CONFIGURE_FLAG= build_one to
#arm v6 CPU=armv6 OPTIMIZE_CFLAGS="-marm -march=$CPU" PREFIX=./android/$CPU ADDITIONAL_CONFIGURE_FLAG= build_one (I thought changing it to armv6 would build ffmpeg compatible with armeabi devices. m I wrong?)
Doubt 1:
Do I also have to change toolchain?
i.e from arm-linux-androideabi-4.4.3 to arm-eabi-4.4.0 ?????
Doubt 2:
When I try running ./build.sh (without changing toolchain) it gives me following error:
/home/chaitanya/android/android-ndk-r5b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc is unable to create an executable file. C compiler test failed. If you think configure made a mistake,.. blaah blahh blaah after that I got lot of warnings saying:
‘sub_id’ is deprecated and many other function deprecated warnings.
platform: ubuntu 11.10
ffmpeg version: 0.11.2
NDK : android-ndk-r5b
Here is my build script:
