From aebfbbf2bdda8e18beef90c16da97bd335f7d3b0 Mon Sep 17 00:00:00 2001 From: wm4 Date: Sun, 12 Aug 2012 15:30:21 +0200 Subject: Remove win32/qt/xanim/real binary codecs loading Remove the win32 loader - the win32 emulation layer, as well as the code for using DirectShow/DMO/VFW codecs. Remove loading of xanim, QuickTime, and RealMedia codecs. The win32 emulation layer is based on a very old version of wine. Apparently, wine code was copied and hacked until it was somehow able to load a limited collection of binary codecs. It poked around in the code segment of some known binary codecs to disable unsupported win32 API calls to make them work. Example from module.c: for (i=0;i<5;i++) RVA(0x19e842)[i]=0x90; // make_new_region ? for (i=0;i<28;i++) RVA(0x19e86d)[i]=0x90; // call__call_CreateCompatibleDC ? for (i=0;i<5;i++) RVA(0x19e898)[i]=0x90; // jmp_to_call_loadbitmap ? for (i=0;i<9;i++) RVA(0x19e8ac)[i]=0x90; // call__calls_OLE_shit ? for (i=0;i<106;i++) RVA(0x261b10)[i]=0x90; // disable threads Just to show how utterly insane this code is. You wouldn't want even your worst enemy to have to maintain this. In fact, it seems nobody made major changes to this code ever since it was committed. Most formats can be decoded by libavcodecs these days, and the loader couldn't be used on 64 bit platforms anyway. The same is (probably) true for the other binary codecs. General note about how support for win32 codecs could be added back: It's not possible to replace the win32 loader code by using wine as library, because modern wine can not be linked with native Linux programs for certain reasons. It would be possible to to move DirectShow video decoding into a separate process linked with wine, like the CoreAVC-for-Linux patches do. There is also the mplayer-ww fork, which uses the dshownative library to use DirectShow codecs on Windows. --- loader/resource.c | 487 ------------------------------------------------------ 1 file changed, 487 deletions(-) delete mode 100644 loader/resource.c (limited to 'loader/resource.c') diff --git a/loader/resource.c b/loader/resource.c deleted file mode 100644 index c15b308c69..0000000000 --- a/loader/resource.c +++ /dev/null @@ -1,487 +0,0 @@ -/* - * Resources - * - * Copyright 1993 Robert J.
