Mplayer 不能播放 MSS 编码的 wmv 格式视频

影音多媒体

系统是 12.3 64 位的，安装了 smplayer、mplayer 和 win32codecs-all，可以播放 mkv、rmvb 格式的，但就是不能播放 wmv 格式的，求指教

2

ffmpeg 可以解码 wmv, 你安装一下试试

win32codecs 这玩意感觉现在它貌似不起任何作用～

4

怎么安装的。

5

安装 packman 源 http://ftp.skynet.be/pub/packman/suse/openSUSE_12.3/，然后 zypper 安装 mplayer、smplayer、win32codecs-all

6

我装了 ffmpeg，但是我怎么使用 mplayer 关联到 ffmpeg 这个解码器呢？

7

别听他瞎说，mplayer 编译时内置 ffmpeg，它根本不用系统的 ffmpeg。

另外 Packman 源的 mplayer 支持 wmv，我刚放过。

你在终端运行：

mplayer 你的视频.wmv

看有什么错误输出。

是不是WMV9不支持，显示这些信息，你看看

精简下错误基本是这些。

第一个错误，你是 Nvidia 显卡吗？是的话装一下 libvdpau1 和 vdpau-video。看看消失没。不是 Nvidia 显卡就请当它不存在。

第二个错误是 MSS 编码的 WMV 需要编译时支持 32 位的 w32codec-all，我回头看看我们的 MPlayer。

参考：[ubuntu] 64 bit Ubuntu can not play MSS2 video encoded WMV files?

wmsdmod 和 wms10dmod 是 w32codec-all 里面的两个 dll：

mplayerhq.hu/MPlayer/DOCS/codecs-status.html

第三个错误是 FFMpeg 尚未实现 WMAPro 功能。查了下最新的 FFMpeg git tree，依然未实现：

git.videolan.org/?p=ffmpeg.git;a=blob;f=libavcodec/wmavoice.c;h=1bf2497667e2464b233f63cd8aa7536124f5be76;hb=HEAD

avpriv_request_sample(ctx, “WMAPro-in-WMAVoice”);
