copied!<p>I agree with Mark. Among the C/C++ libraries are ffmpeg <a href="http://www.ffmpeg.org/" rel="noreferrer">here</a> or X264 <a href="http://www.videolan.org/developers/x264.html" rel="noreferrer">here</a>. I have to say I havn't found them or the Android NDK easy to use but that's probably because I don't really know much about C/C++ and JNI. If you're interested in this route, then the RockPlayer free app for Android has the pre-built shared libraries from ffmpeg ready for use on Android. They claim these libraries only use LGPL components but you'd have to satisfy yourself on this, I guess. With regards to Java, there is a port (of sorts) of ffmpeg called, unsurprisingly, jffmpeg which you can access <a href="http://jffmpeg.sourceforge.net/" rel="noreferrer">here</a> but it still calls out to much of the existing ffmpeg framework, so you're back in NDK land. It is possible to convert a series of images to video with the Java Media Framework (JMF) but it has the following drawbacks:</p> <ol> <li>Limited number of video formats.</li> <li>Doesn't produce videos which can be played back on most (if not all) Android phones e.g. H264 or MPEG4.</li> <li>The JMF code is now quite old, hasn't progressed in a long time, is bloated and not well structured so there may be additional Java dependencies which are not packaged in Android.</li> </ol> <p>Another option I've seen used is Adobe Air, but it's a 17Mb payload which some users complain about.</p> <p>There are lots of other questions here on Stack Overflow regarding ffmpeg and Android NDK.</p> <p>Good luck with the project.</p>
