基於 LIBVLC sdk 開發

本文來自csdn lidp http://blog.csdn.net/perfectpdl, 轉載註明出處，謝謝。

基於 libvlc庫的開發可以把vlc的功能嵌入我們自己的應用程式中，下面為linux平台(centos)使用libvlc庫的開發過程。

1.安裝libvlc sdk

linux平台直接可以 用命令安裝，centos平台 命令為  yum install libvlc-devel

也可以基於官方源碼安裝(git://git.videolan.org/vlc.git)。 

安裝後會有動態庫 libvlc,so和標頭檔。

2.  基於sdk api 開發

在程式中需要引入標頭檔 vlc.h

#include <stdio.h> #include <stdlib.h> #include <vlc/vlc.h>  int main(int argc, char* argv[]) {     libvlc_instance_t * inst;     libvlc_media_player_t *mp;     libvlc_media_t *m;          /* 載入 VLC 引擎 */     inst = libvlc_new (0, NULL);       /* Create a new item */     m = libvlc_media_new_path (inst, "http://mytest.mov");             /* Create a media player playing environement */     mp = libvlc_media_player_new_from_media (m);          /* No need to keep the media now */     libvlc_media_release (m);  #if 0     /* 下面的代碼為具體平台像或聲音渲染的控制代碼 */      libvlc_media_player_set_xdrawable (mp, xdrawable);     /* or on windows */      libvlc_media_player_set_hwnd (mp, hwnd);     /* or on mac os */      libvlc_media_player_set_nsobject (mp, view);  #endif      /* play the media_player */     libvlc_media_player_play (mp);         sleep (10); /* Let it play a bit */         /* Stop playing */     libvlc_media_player_stop (mp);      /* Free the media_player */     libvlc_media_player_release (mp);      libvlc_release (inst);      return 0; }

3. 編譯 

需要引入庫檔案 libvlc.so

gcc -I ${VLC_SRC}/include/  -lvlc -L VLC_LIBS   test.c
-vlc -o test 

4. 總結

上面只是使用libvlc的基本過程，libvlc sdk提供了很多api 給外部介面，比如指定音頻或者視頻流的回調等。

下面是我摘出來的可用的api
