GStreamer安裝缺少插件

我希望有人可以幫助解決這個問題，一直在尋找過去兩天的解決方案。GStreamer安裝缺少插件

爲了描述短的問題：我試圖做一個簡單的qt5.7應用程序，將流的M3U8（使用Qt創建者（社區），但是當我嘗試運行它，我得到一個

Warning: "No decoder available for type 'application/x-hls'." 
Error: "Your GStreamer installation is missing a plug-in."
。

「GST-檢查| grep的HLS」 回報：typefindfunctions：應用程序/ x-HLS：M3U8

在這一點上我不知道哪個插件可我甚至錯過，因爲我已經走線槽完整的GStreamer插件列表並且一個接一個地投入。 就我的搜索而言，通過安裝糟糕/醜陋的插件得到了一些解決方案。 QT5仍然使用gstreamer0.10，但新的linux版本使用1.0（此時丟失）。我試圖設置一個標誌來強制GST_VERSION = 1.0，沒有工作，或者我做了錯誤的事情（我使用了qmake GST_VERSION = 1.0命令）。另外，我可以在vlc中播放視頻。 我完全卡住了，不知道該做什麼了。

應用代碼：

import QtQuick 2.7 
import QtQuick.Window 2.2 
import QtMultimedia 5.7 

Window { 
    visible: true 
    width: 640 
    height: 480 
    title: qsTr("Hello World") 

    Item { 
     width: 640 
     height: 480 

     MediaPlayer { 
      id: player 
      source: "http://playertest.longtailvideo.com/adaptive/wowzaid3/chunklist_w249832652.m3u8" 
     } 

     VideoOutput { 
      anchors.fill: parent 
      source: player 
     } 

     Component.onCompleted: { 
      player.play(); 
     } 
    } 
}

的HLS插件是在GST-插件壞。確定請檢查 「gst-inspect-1.0 | grep hls」 - 在您的發行版上，gst-inspect可能是gst-inspect-0.10的符號鏈接。

缺失的元素名爲hlsdemux，並且住在gst-plugins-bad中。您可以通過gst-inspect-0.10或gst-inspect-1.0查看已安裝的插件列表。在grep中使用它可以讓你快速發現是否安裝了它。

gst-inspect-1.0 | grep hlsdemux（或0.10取決於您要使用的版本）

如果QtMultimedia確實使用了0.10，你應該丟失gstreamer0.10-plugins-bad。請注意，0.10已經過時並且已經多年不知。 1.0正在積極開發中。你應該檢查一下QtMultimedia的更新版本是否已經升級到1.0版本並嘗試使用它。

您需要確定qtmultimedia正在使用哪個版本。 1.0和0.10是單獨的和不兼容的 – thiagoss
