Starting from scratch is certainly a viable option. Going straight to
d would not solve the problem for Phonon4, or Qt4 for that matter as
Phonon5 is supposed to be exclusively Qt5. However from a backend POV
there is not going to be a whole lot difference between the two
versions as Phonon5's key element is getting rid of pointless API
dynamics and through that simplifying the frontend API (like not
having a mediagraph where in theory one could order nodes in any order
and something reasonable should come out at the end). The heavy
lifting code of setting a source, building a pipeline and making it
create output should be largely the same.

I personally would go for a rewrite but at the same time I am also
very confident that starting from the existing code base would yield
success. Torrie Fischer already rewrote a lot of the pipeline building
and control logic a while ago, so it is most certainly not as bad as
it used to be. At the very least there is stuff that can be salvaged
for a possible rewrite.

There definitely are solid reasons for having a GStreamer backend,
otherwise it would have gotten the boot like all the other broken
backends years ago. While I had not originally thought of mobile
devices, it certainly has even greater importance there. Regardless of
the device though it would be a shame to loose the backend, so I
really hope someone who enjoys HD videos steps up and volunteers to
make software to play them (better) :)
