VLC的官网：http://www.videolan.org/
VLC源码下载地址：http://download.videolan.org/pub/videolan/vlc/2.2.4/
测试代码参考雷神的博客：http://blog.csdn.net/leixiaohua1020/article/details/42363079
qt环境搭建教程
下载vlc源码
点击下载地址选择win64/win32,我选的是win64，下载.7z结尾的，我下载的是vlc-2.2.4-win64.7z
下载解压之后是下面这个样子
解压后找到sdk文件夹，这个文件夹非常重要
第一次提交代码，最简单的libvlc播放器
创建控制台项目（参考qt环境搭建教程）
配置.pro文件
在底部添加如下代码
win32{
INCLUDEPATH += $$PWD/sdk/include
LIBS += -L$$PWD/sdk/lib -llibvlc -llibvlccore
}else{
INCLUDEPATH += /usr/local/include
LIBS += -L/usr/local/lib -lvlc -lvlccore
}
将解压后的sdk文件夹复制到main.cpp文件夹下即可
测试代码见simple_libvlc_qt_player
运行结果播放cuc_ieschool.flv这个视频
#include <QCoreApplication>
#include <Windows.h>
#include "vlc/vlc.h"
using namespace std;
int main(int argc, char* argv[])
{
libvlc_instance_t* inst;
libvlc_media_player_t* mp;
libvlc_media_t* m;
libvlc_time_t length;
int width;
int height;
int wait_time = 5000;
const char* version;
version = libvlc_get_version();
printf("version: %s\n", version);
inst = libvlc_new(NULL, NULL);
char filename[1024] = "../simple_libvlc_qt_player/cuc_ieschool.flv";
//m = libvlc_media_new_location (inst,"rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov" );
m = libvlc_media_new_path (inst,filename);
mp = libvlc_media_player_new_from_media(m);
libvlc_media_release(m);
libvlc_media_player_play(mp);
//wait until the tracks are created
_sleep(wait_time);
length = libvlc_media_player_get_length(mp);
width = libvlc_video_get_width(mp);
height = libvlc_video_get_height(mp);
printf("Stream Duration: %ds\n", length / 1000);
printf("Resolution: %d x %d\n", width, height);
//Let it play
_sleep(length - wait_time);
// Stop playing
libvlc_media_player_stop(mp);
libvlc_media_player_release(mp);
libvlc_release(inst);
return 0;
}
在
simple_libvlc_qt_player文件夹下有一个release文件夹将里面的动态链接库放到打包的程序目录下即可发布
