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. |

README
Compiling with full features requires development files for several external libraries. Below is a list of some important requirements. For more information see the output of './configure --help' for a list of options, or look at the list of enabled and disabled features printed after running './configure'. If you think you have support for some feature installed but configure fails to detect it, the file config.log may contain information about the reasons for the failure. Libraries specific to particular video output methods (you'll want at least one of VDPAU, GL or Xv): - libvdpau (for VDPAU output, best choice for NVIDIA cards) - libGL (OpenGL output) - libXv (XVideo output) general: - libasound (ALSA audio output) - various general X development libraries - libfreetype (for libass) - libfontconfig (for libass) - libass - FFmpeg libraries (libavutil libavcodec libavformat libswscale libpostproc) Most of the above libraries are available in suitable versions on normal Linux distributions. However FFmpeg is an exception (distro versions may be too old to work at all or work well). For that reason you may want to use the separately available build wrapper that first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those.
