Android , Java - Rendering a video using bitmap frames to reverse a video (Xuggler)


You can use ffmpeg to assemble video from images. You can integrate ffmpeg in Java(Android) in a couple of ways (one being directly running it via

Runtime.getRuntime().exec("ffmpeg <options>");

), but probably a good way to do it is via the Xuggler project - it heavily relies on ffmpeg. For starting point, here's a set of introduction tutorials and here's a complete tutorial how to encode video from sequence of images. It's a lot of work and reading, but all the information you need is there. Good luck!


Regarding your xuggler usage, the version of your library won't work on your specific device, as it contains native code compiled for x86_64 and i686 platforms:

[2012-08-18 00:29:16 - xugglertest2]  - com/xuggle/ferry/i686-pc-linux-gnu/[2012-08-18 00:29:16 - xugglertest2]  - com/xuggle/ferry/x86_64-pc-linux-gnu/

try finding version of this library with native code parts compiled for ARMv6 (most common Android architecture - includes older devices, if don't want to support devices older than ~1-2 years ago, ARMv7 would be better).

Otherwise, you'll need to get the ffmpeg compiled for ARM and use it with support of Android NDK. You'll need to write a code in C/C++ implementing encoding your series of images into a specific file and wrap it up with JNI interface. You can pass Java arrays to native implementations of class' methods.

please see sample Android NDK applications in SDK samples to see how to use JNI in your code
