/* * vo_dxr3.c - DXR3/H+ video out * * Copyright (C) 2002 David Holm * */ /* ChangeLog added 2002-01-10 * 2002-04-03: * Carl George added spuenc support * * 2002-03-26: * XorA added an option parser and support for selecting encoder * codec. We thank him again. * * 2002-03-25: * A couple of bugfixes by XorA * * 2002-03-23: * Thanks to Marcel Hild the jitter-bug experienced * with some videos have been fixed, many thanks goes to him. * * 2002-03-16: * Fixed problems with fame, it gives a better picture than avcodec, * but is slightly slower. Most notably the wobbling effect is gone * with fame. * * 2002-03-13: * Preliminary fame support added (it breaks after seeking, why?) * * 2002-02-18: * Fixed sync problems when pausing video (while using prebuffering) * * 2002-02-16: * Fixed bug which would case invalid output when using :noprebuf * Removed equalization code, it caused problems on slow systems * * 2002-02-13: * Using the swscaler instead of the old hand coded shit. (Checkout man mplayer and search for sws ;). * Using aspect function to setup a proper mpeg1, no more hassling with odd resolutions or GOP-sizes, * this would only create jitter on some vids! * The swscaler sometimes exits with sig8 on mpegs, I don't know why yet (just use -vc mpegpes in this * case, and report to me if you have any avi's etc which does this...) * * 2002-02-09: * Thanks to the new control() method I have finally been able to enable the em8300 prebuffering. * This should speed up playback on all systems, the vout cpu usage should rocket since I will be hogging * the pci bus. Not to worry though, since frames are prebuffered it should be able to take a few blows * if you start doing other stuff simultaneously. * * 2002-02-03: * Removal of libmp1e, libavcodec has finally become faster (and it's code is helluva lot cleaner) * * 2002-02-02: * Cleaned out some old code which might have slowed down writes * * 2002-01-17: * Testrelease of new sync engine (using previously undocumented feature of em8300). * * 2002-01-15: * Preliminary subpic support with -vc mpegpes and dvd's * Device interfaces tries the new naming scheme by default (even though most users probably still use the old one) * * 2002-01-10: * I rehauled the entire codebase. I have now changed to * Kernighan & Ritchie codingstyle, please mail me if you * find any inconcistencies. */ #include #include #include #include #include #include #include #include #include #include #include #include #include "config.h" #include "fastmemcpy.h" #include "video_out.h" #include "video_out_internal.h" #include "aspect.h" #include "postproc/rgb2rgb.h" #include "postproc/swscale.h" #include "cpudetect.h" #include "spuenc.h" #define USE_LIBFAME /* Libfame codec initialisation */ #ifdef USE_LIBFAME #include "../libfame/fame.h" static unsigned char *outbuf = NULL;
