/* * vo_dxr3.c - DXR3/H+ video out * * Copyright (C) 2002 David Holm <dholm@iname.com> * */ /* ChangeLog added 2002-01-10 * 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 <linux/em8300.h> #include <sys/ioctl.h> #include <sys/stat.h> #include <sys/types.h> #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <fcntl.h> #include <stdio.h> #include <time.h> #include "config.h" #include "fastmemcpy.h" #include "video_out.h" #include "video_out_internal.h" #include "../postproc/rgb2rgb.h" #ifdef USE_LIBAVCODEC #ifdef USE_LIBAVCODEC_SO #include <libffmpeg/avcodec.h> #else #include "libavcodec/avcodec.h" #endif /* for video encoder */ static AVCodec *avc_codec = NULL;
