Unable to get GstClock from GstElement

[svenyonson]

Thanks Sebastian, I will do this in the future.

Olivier has created a patch that I would like to try (attached to the bug report). I assume this means that I will need to build GStreamer from sources for the ARM/Android platform? 

Are there instructions/scripts for doing this? Hopefully to create a drop in replacement for the gstreamer-1.0-android-arm-debug-1.4.4 SDK that I downloaded earlier? Or would this available from nightly builds?

Thanks for all of your help.

Steve
