在已安装的 gstreamer1.0 中找不到 uridecodebin

Question

我正在尝试 gstreamer SDC 文档中的示例。

特别是this page，建议像这样使用URIDecodebin：

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

但我立即收到此错误：

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

我关注 this installation instruction Ubuntu。

我已经安装了这些东西：

i  gstreamer1.0-libav - libav plugin for GStreamer

如何安装 uridecodebin？或者它是否已被弃用并且应该被忽略？

Answer 1

你的管道有两个错误

一个是错误的路径file:///test.ogg（需要有绝对路径），
有两个的部分！！中间没有元素..

这对我有用（希望您将从 test.ogg 的位置执行）：

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

当然不会弃用 uridecodebin.. 你可以用命令检查你是否拥有它：

gst-inspect-1.0 uridecodebin - shell 输出有关元素的详细信息

在已安装的 gstreamer1.0 中找不到 uridecodebin

uridecodebin not found in installed gstreamer1.0
