Introduction

VLC is a free and open source cross-platform multimedia player and framework that can play most multimedia files, as well as DVD, audio CD, VCD and various streaming media protocols.
Since VLC is completely open source, we can obtain all the project source code and carry out secondary development on this basis

VLC official website: http://www.videolan.org/

VLC source code download address: http://download.videolan.org/pub/videolan/vlc/2.2.4/

The test code refers to Raytheon's blog: http://blog.csdn.net/leixiaohua1020/article/details/42363079

VS configure vlc development environment

Which version of VS is fine, preferably VS2013 and above, I use VS2019

Download vlc source code

Click on the download address to choose win64/win32, I chose to win64download the one ending in .7z, and I downloadedvlc-2.2.4-win64.7z

After downloading and decompressing, it looks like this

Find the sdk folder after decompression, this folder is very important

Create a vlc environment

Open VS2019 and create a new console application project

Adjust the project properties to Debug x64 mode (I downloaded the 64-bit version), as shown in the figure below

Open the project-project properties window, add the sdk\include in the vlc file directory you unzipped to the "additional include directory" under the C/C++ option

Add the sdk\lib in the vlc file directory you unzipped to the "additional library directory" under the linker options

Finally, copy the plugins folder in the vlc file directory and the two files libvlc.dll and libvlccore.dll to the \x64\Debug directory of your project. If there is no such directory, first menu bar -> generate -> generate solution, the directory will be there

The development environment configuration under vlc VS is complete

Test vlc code

#include <Windows.h>
#include "vlc/vlc.h"
#pragma comment(lib,"libvlc.lib")
#pragma comment(lib,"libvlccore.lib")

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] = "cuc_ieschool.flv";
    //播放网络文件
    //m = libvlc_media_new_location (inst,"rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov" );
    //播放本地文件
    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;
}
