我希望有人可以在过去2天寻找解决方案的情况下为您提供帮助.
简而言之,描述问题:我正在尝试制作一个简单的qt5.7应用程序,该应用程序将流m3u8(使用Qt Creator(社区).但是当我尝试运行它时,我得到了一个
Warning: "No decoder available for type 'application/x-hls'."
Error: "Your GStreamer installation is missing a plug-in."
“ gst-inspect | grep hls”
返回值:typefindfunctions:应用程序/ x-hls:m3u8
在这一点上,我什至不知道我会错过哪个插件,因为我已经浏览了完整的GStreamer插件列表并一个接一个地放置.
就我的搜索而言,有些错误是通过安装不良/丑陋的插件得到的.有人说QT5仍然使用gstreamer0.10,但是新的Linux版本使用1.0(此时已丢失).我试图设置一个标志来强制使用GST_VERSION = 1.0,但它不起作用,或者我做错了什么(我使用了qmake GST_VERSION = 1.0命令).另外,我可以在vlc中播放视频.
我完全被困住了,不知道该怎么办了.

解决方法:
hls插件位于gst-plugins-bad中.可以肯定的请检查
“ gst-inspect-1.0 | grep hls”-在您发行的gst-inspect上可能是gst-inspect-0.10的符号链接.
