Hi,

Hardware accelerated decoders are only available in Android >= 4.2 as they
depend on the public Media Codec API, which was added in API level 16. The
default set of plugins used in the tutorials only support codecs that are
already available in the device or open codecs without any license/patent
restrictions. You will need to include manually the ffmpeg plugin to
support a bigger lists of formats or contact Fluendo for licensed decoders
that you can use a distribute legally.

Cheers,
Andoni
