在安裝的gstreamer1.0中找不到uridecodebin

Question

我在嘗試gstreamer SDC文檔中的例子。

特別this page，建議使用URIDecodebin這樣的：

gst-launch-1.0 uridecodebin uri=file:///test.ogg ! ! audioconvert \ 
    ! audioresample ! autoaudiosink 

但我立即得到這個錯誤：

ERROR: pipeline could not be constructed: no element "uridecodebin". 

我跟着this installation instruction的Ubuntu。

我得到了安裝這個東西已經：

i gstreamer1.0-alsa - GStreamer plugin for ALSA 
i gstreamer1.0-clutter - Clutter PLugin for GStreamer 1.0 
i gstreamer1.0-libav - libav plugin for GStreamer 
i gstreamer1.0-nice - ICE library (GStreamer plugin)

i gstreamer1.0-plugins-good - GStreamer plugins from the "good" set

i libgstreamer1.0-0 - Core GStreamer libraries and elements 
i libgstreamer1.0-0:i386 - Core GStreamer libraries and elements 
i phonon-backend-gstreamer1.0 - transitional package 

如何獲得安裝uridecodebin？或者是否被棄用，應該被忽略？

Answer 1

你有兩個錯誤在你管

• 一個是錯誤的路徑文件：///test.ogg（你需要有絕對路徑），
• 兩部分！ ！在中間沒有元素..

這是爲我工作（希望你會從test.ogg的位置執行）：

gst-launch-1.0 uridecodebin uri=file://`pwd`/test.ogg ! audioconvert ! audioresample ! autoaudiosink 

uridecodebin肯定不會被棄用.. 可以檢查您是否有命令有它：

gst-inspect-1.0 uridecodebin - 貝約的元素
