Do I need both the 1.4.5 binaries and the GStreamer SDK? The GStreamer 1.4.5 binaries contain everything that the "GStreamer SDK" contains, just 3 years newer. > 2.

You just need to extract the binaries to some please and then set GSTREAMER_ROOT_ANDROID in the environment to that place. Then you can just build them like any other Android project. > 3.

Which tutorials are more current, ~slomo or the GStreamer SDK? See above :) > 5. Is it possible to run something like the command line gst-launch > application on Android to test pipelines and installations? Yes but command line applications don't have access to the hardware codecs and other things, and you need a rooted device.
