           Summary: gstreamer SPC plugin requires non-portable x86 code

          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED

gst-spc, the SNES SPC playback plugin uses OpenSPC, which is coded in raw,
nearly unpenetrable x86 assembly, limiting it to x86 and x86_64.

Luckily the emulation state of the art has advanced since then an a suitable
replacement library written in nearly unpenetrable C++ is available (and useful
on even PPC in theory for instance).  This is Shay Smith's snes_spc
(http://slack.net/~ant/libs/audio.html#snes_spc), as used by bsnes and now
zSNES and available under the LGPL.

I've prepared a patch utilizing this library (including it inline, v0.9.0,
instead of making it a dependency, as done with the similar NSF plugin), which
I will attach.  I suppose the naming convention would move spc from /ext to
/gst but I'll let you guys handle your directory layout. ;)

There's probably a porting bug or two (notably, I've not been able to test
seeking with gst-launch and I couldn't get eina to work, and I don't really
feel like waiting for anything larger to compile to test... :-/).  Hopefully
nothing major, if you have any question feel free to drop me a line.  Thanks.
