    <p>I am working on an Android app where I want to create a video from a list of static images. After doing some search on internet, it made me realized that using "FFMPEG" is the way to go in getting this thing done. So I got hold of this site: <a href="https://github.com/guardianproject/android-ffmpeg-java" rel="nofollow">https://github.com/guardianproject/android-ffmpeg-java</a> from where I downloaded the C library and the Java wrapper. I was able to compile the C library - of course not the way the instruction was laid out - but still I was able to get "ffmpeg" executable under /external/android-ffmpeg/ffmpeg directory. I copied that executable in my current directory and then copied it to a directory under Android where my app can access it. Then I called the provided Java wrapper but I am seeing some errors in the log file like follows:</p> <pre><code>08-13 11:55:37.848: D/FFMPEG(29598): /data/data/com.sample/app_bin/ffmpeg -y -loop 1 -i /storage/emulated/0/usersnapshot/ffmpeg/image%03d.jpg -r 25 -t 2 -qscale 5 /storage/emulated/0/video/snapshot-video.mp4 08-13 11:55:37.898: I/ShellCallback : shellOut()(29598): /data/data/com.sample/app_bin/ffmpeg[1]: syntax error: '(' unexpected 08-13 11:55:37.938: I/ShellCallback : processComplete()(29598): 1 </code></pre> <p>And following is the code snippet (where targetDirectoryForFFMPEG = directory where the images are stored):</p> <pre><code>FfmpegController ffmpegController = new FfmpegController(this, targetDirectoryForFFMPEG); String out = videoOutPutFile.getPath(); MediaDesc mediaIn = new MediaDesc(); mediaIn.path = targetDirectoryForFFMPEG+"/image%03d.jpg"; mediaIn.videoFps = "25"; ffmpegController.convertImageToMP4(mediaIn, 2, out,new ShellCallback() { @Override public void shellOut(String shellLine) { Log.i("ShellCallback : shellOut()", shellLine); } @Override public void processComplete(int exitValue) { Log.i("ShellCallback : processComplete()", exitValue+""); } }); </code></pre> <p>Has anybody implemented this before? If yes, can you point me to what am I doing incorrect? I will provide more information if needed.</p>
