+Summary: divx/xvid crash gst-register
+
+XviD/DivX apparently share several public symbols ("grep divx
+/usr/lib/libxvidcore.so" to see for yourself). gst-register loads and
+unloads each plugins. Unloading is apparently unimplemented. Therefore,
+xvid will overrule the divx symbols before divx can load itself, or divx
+will load symbols which xvid wants to overrule. The one makes the other crash.
+
+xvid will segfault in xvid_init() if divx was loaded first. divx versions
+etc. will be overrules by xvid and the version check in the divx plugin
+(because divx4linux isn't ABI/API stable) therefore fails if xvid was
+loaded before divx, and the plugin fails to load.
+
+I don't know how to solve it, apart from kicking the hell out of the xvid
+people for screwing up so badly (they overrule divx symbols, but not the
+other way around). Anyone knows a better (working ;) ) solution for this
+issue? Even if we'd implement plugin unloading, we still wouldn't be able
+to load xvid/divx plugins in the same pipeline. :(.
