FFmpeg/libx264 build for android1) Requirement

-Ndk R4: Please use ndk R4 instead of ndk R3.

-Using ndk R4 new option, you can know the detail build option.

-Please get FFMPEG http://www.ffmpeg.org/download.html

-Please get libx264 http://www.videolan.org/developers/x264.html

2) Build option for libx264

Export arm_root =/export/home/Android/ndk
Export arm_inc = $ arm_root/build/platforms/Android-5/arch-arm/usr/include/
Export arm_lib = $ arm_root/build/platforms/Android-5/arch-arm/usr/lib/
Export arm_tool = $ arm_root/build/prebuilt/linux-x86/arm-eabi-4.4.0
Export arm_libo = $ arm_tool/lib/GCC/ARM-Eabi/4.4.0
Export Path = $ arm_tool/bin: $ path
Export arm_pre = arm-Eabi

3) Build option for FFMPEG

4) You will get 4 files ..

-FFMPEG, ffprobe, ffserver, x264.
-Because we didn't ready SDL, we can't get ffplay.

5) how to use it?

-Because Android support a few codecs, it's a little bit difficult to play some common files.
So, FFMPEG/ffserver will run on Android device to change stream format.

-For this one, Howard Chu, FFMPEG team member already check it. https://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2010-May/088706.html

-Screen capture to use ffserver/FFMPEG to play h264/AAc/mpeg ps stream file on Android emulator.

 

-Unfortunately, the x264 doesn't work well on Android, need to check x264/FFMPEG.
