Hi, 
I am trying to build tutorial 5 for Android with ffmpeg plugin, but I am getting following linking error:

Looks like av_malloc, av_realloc and av_free are beeing defined both in ffmpeg and ffmpegcolorspace.

Thanks.

This one is already fixed:
http://cgit.freedesktop.org/gstreamer-sdk/gst-plugins-base/commit/?id=8599175207e044ad5a46edc81ed9166dd3175157

You will need to rebuild gst-plugins-base-static

Could you give me a hint on how to rebuild this as well as from where to clone the repository?

It's documented here in the "Cross-compilation of the SDK" section:
