PODoes anyone find this useful? - Compiling FFMPEG on Windows with Cywin and NDK r5
text
Body
copied!<p>Does anyone find this information useful in anyway?</p> <p>I've been trying to compile this thing for a while now and I know of the numerous posts floating around the internet offering help. I have read and tried most of the suggestions and wanted to colate my success into this single post for others to benefit from.</p> <p>Since I don't have a blog, I thought it wouldn't hurt to post on here instead.</p> <p>I have managed to compile FFMPEG 0.10.3 (Freedom) on Windows 7 (32 bit) using NDK r5 and Cygwin. The steps:</p> <p>1 - Download/install Cygwin in the root of your C drive. I'm not going to give instructions on this, it's simple enough and there <em>are</em> plenty of tutorials on this.</p> <p>2 - Download NDK r5 from <a href="http://dl.google.com/android/ndk/android-ndk-r5-windows.zip" rel="nofollow noreferrer">here</a> and extract to the root of your C drive.</p> <p>3 - Download FFMPEG 0.10.3 from <a href="http://ffmpeg.org/download.html" rel="nofollow noreferrer">here</a> and extract to the root of your C drive.</p> <p>4 - Open the file 'configure' in the root of the FFMPEG directory in a text editor.</p> <p>5 - Comment out lines 2073, 2074 and 2075.</p> <p>6 - Below 2075, add the following line: </p> <blockquote> <p>TMPDIR=c:/cygwin/tmp</p> </blockquote> <p>7 - Download <a href="http://roman10.net/src/build_android_r5b.txt" rel="nofollow noreferrer">this</a> script (thankyou roman10) and place it inside your FFMPEG root directory. Rename the file to </p> <blockquote> <p>build_android.sh</p> </blockquote> <p>8 - Open the script in a text editor and edit line 17 to read </p> <blockquote> <p>c:/android-ndk-r5</p> </blockquote> <p>9 - Click start > run and type "bash" (without the speech marks) and press enter.</p> <p>10 - Type the following and press enter: </p> <blockquote> <p>cd /cygdrive/c/ffmpeg-0.10.3</p> </blockquote> <p>11 - Type the following and press enter: </p> <blockquote> <p>dos2unix build_andoird.sh</p> </blockquote> <p>12 - Type the following and press enter: </p> <blockquote> <p>./build_android.sh</p> </blockquote> <p>13 - Sit back and wait... libffmpeg.so will soon appear in your "c:\ffmpeg-0.10.3\android\" directory (where is defined in the bottom of the script from roman10's blog). The default architecture is armv7-a.</p> <p>The script from roman10's blog will actually compile quite a large shared object (.so) file. The compiler flags can be adjusted to suit your needs in the script from roman10's blog.</p>
