[gst-devel] How to use Gstreamer framework for hardware based video decoder ?

I haven't looked at the h264 encoder in gstreamer; but for a lot of
modules; gstreamer provides a wrapper around an external library
(jasper, ffmpeg).

The GStreamer buffers are prepared and passed to the library, the result
is put back in GStreamer buffers.

A hardware encoder would probably be the same.

And as for all the calls; you'd only need to expose the parameters that
your hardware encoder knows/uses.
