求助Qt5的Media Player Example如何播放视频
我用的是VMware虚拟机装的Centos6.3。用Qt5的例子编译完运行，可以播放mp3，但是不能播放视频，试过mp4和mkv，都没成功，下面一堆报错，显示：
Starting /mnt/hgfs/share/video-player/build-player-Desktop_Qt_5_1_1_GCC_64bit-Debug/player...

但是我用centos application里的播放器都可以播放mp4和mkv的，这说明视频解码的库我应该都有了，但不知道是哪里出了问题？ qt5 mp4 mkv 视频 centos --------------------编程问答-------------------- 没有知道吗？ --------------------编程问答-------------------- = =b 正在研究 问题差不多。
补充：移动开发 , Qt
