*.mp4 视频文件用什么播放器来放

robinswan

下了个*.mp4的视频文件，但是不知道用什么东西来放，MPlayer 也放不了。

命令行里放，有错误信息的，贴出来
肯定是少什么USE

有图像没声音。

那可能是解码器没装，还有可能是系统声音没配置好，别的程序有声音吗？
还有可能是mplayer的声音输出的设置没弄好。

至于解码器，这是我的USE，你可以参考下（我几乎把能选的都选了），现在我用smplayer作前端，除了.ts的不能放外，都成万能播放器了！

mp4一般是H.264的视频，AAC的音频，USE里面加个AAC和x264应该就可以了

everyoung

ts也能放的，ts只是一种封装格式，具体要看编码，我这里目前只有VC-1还不能放，其他的主流格式都没问题，就是高清视频很不流畅，h.264的解码器还不成熟
