copied!<p>I am trying to compile ffmpeg for android armeabi devices. <br /> I am following tutorial by <a href="http://www.roman10.net/how-to-build-ffmpeg-for-android/" rel="noreferrer">roman10.net</a> <br /> His given build script builds ffmpeg for armv7-a devices. I want to build it for armeabi. <br /> </p> <p><strong>My ultimate aim is to run ffmpeg commands on android armeabi and armv7-a devices.</strong></p> <p>So I change the script's CPU part from</p> <pre><code>#arm v7vfpv3 CPU=armv7-a OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=vfpv3-d16 -marm -march=$CPU " PREFIX=./android/$CPU ADDITIONAL_CONFIGURE_FLAG= build_one </code></pre> <p>to</p> <pre><code>#arm v6 CPU=armv6 OPTIMIZE_CFLAGS="-marm -march=$CPU" PREFIX=./android/$CPU ADDITIONAL_CONFIGURE_FLAG= build_one </code></pre> <p>(I thought changing it to armv6 would build ffmpeg compatible with armeabi devices. m I wrong?)</p> <p><strong>Doubt 1:</strong> <br /> Do I also have to change toolchain?<br /> i.e from <strong>arm-linux-androideabi-4.4.3</strong> to <strong>arm-eabi-4.4.0</strong> ?????</p> <p><strong>Doubt 2:</strong></p> <p>When I try running ./build.sh (without changing toolchain) it gives me following error: <br /></p> <pre><code>/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 </code></pre> <p>after that I got lot of warnings saying: <br /> ‘sub_id’ is deprecated and many other function deprecated warnings.</p> <p><strong>platform</strong>: ubuntu 11.10 <br /> <strong>ffmpeg version</strong>: 0.11.2 <br /> <strong>NDK</strong> : android-ndk-r5b</p> <p>Here is my build script:</p> <pre><code>#!/bin/bash ###################################################### # Usage: # put this script in top of FFmpeg source tree # ./build_android # It generates binary for following architectures: # ARMv6 # ARMv6+VFP # ARMv7+VFPv3-d16 (Tegra2) # ARMv7+Neon (Cortex-A8) # Customizing: # 1.
