of the real _Init or _Create functions. That's 1000 lines of code gained. * ./src/misc/modules.c: we try not to keep the global lock in module_Need, which should speed up output spawning. * ./plugins/dummy/input_dummy.c: fixed vlc:quit command. * ./plugins/gtk/gtk_playlist.c: compilation fix. * ./plugins/macosx/*: preliminary fixes for the vout4 port. Notes on the *_Probe eradication: o I probably broke the DirectX video output, because of the "must init and run in the same thread" issue. I'll fix this ASAP. o Subtitles are broken (or at least, pretty ugly) in RGB mode. o The input plugins still have *_Probe functions. This will disappear when meuuh is finished with the access plugins. o The decoder plugins still have *_Probe functions. This is probably not going to change, it looks OK to me.
