Hi,

you should start reading the gstreamer docuemntation (also online at
http://gstreamer.freedesktop.org). In addition each source code module
has tests/examples that you can study. Right now the ndk can be used to
write an audio player. We still need to write a working video sink for
the android platform. Existing linux video sinks are mostly unusuable as
android does not provide the apis.
