gst-ffmpeg软件包安装正常，使用出错.

时间：2009-06-21

来源：互联网

为了安装gnash
我安装了Gstreamer,gst-plugin-base, gst-plugin-good,gst-ffmpeg四个包
安装过程还比较顺利，装完以后，我用gst-inspect检查。

#gst-inspect
这里列出好多项目，

#gst-inspect ffdec_flv
这样运行就会提示错误，提示如下：

代码:

查找原因，发现是gst-ffmpeg包的问题。我卸载了gst-ffmpeg包就没有了ffdec_flv这个插件了。

可是我安装gst-ffmpeg包的0.10.3/0.10.4/0.10.7三个版本都不能解决问题。

请坛友帮忙，这个问题是什么引起的？我要怎么解决。
