That's not the reason: The SLPlugin binary, while a separate process
than the viewer main binary, is also shipped only compiled for 32bit in
the official downloads and thus faces the same problem as the main
binary: it can only load 32bit libraries. The reason why it can display
web content anyway, is that the library used for rendering html is also
included (also in 32bit) in the download.

For audio/video stream display, the GStreamer libraries are used, but
those aren't included in the download. So SLPlugin tries to load the
system-installed version (if any), which (if SLPlugin is compiled for
32bit) can only succeed if those libs are compiled for 32bit, too.
So the possibilities would be:
* Include 32bit GStreamer libraries in the official download (or in
a separate download)
o Around 17 MB including common plugins, but still excluding
any dependency libraries that might have to be added for
this to work, too
* Offer SPLugin (and maybe the whole viewer) compiled for 64bit, too
o This would mean additional QA work for LL.
* Have Linux 64bit users install a 32bit GStreamer
o Probably difficult on many distributions (because GStreamer
is usually not part of the 32bit compatibility bundles, such
(I've gone into more detail about the options from the users' point of
view in past explanations

I don't know of any specific one. There's a feature request for offering
official 64bit downloads: VWR-13793

That would indeed make life much easier for non-technical Linux 64bit users.

Although this has been discussed in the past, it's good that someone
brings it up again.
