我正在尝试使用gstreamer播放本地mpeg2 TS文件：
gst-launch filesrc location=open_season.mpg ! mpeg2dec ! xvimagesink
第一帧显示为大块颜色，然后停止。关于我在这里做错了什么的想法？是否需要以不同的方式处理-TS文件？
这是日志：
$ gst-launch filesrc location=open_season.mpg ! mpeg2dec ! xvimagesink

我认为首先应该首先尝试在playbin2的帮助下播放该文件。如果你能够播放它，那么你应该使用decodebin2，调试它的输出并相应地构建你的管道。
playbin2的语法如下： -
gst-launch playbin2 uri = file:///home/user1031040/Desktop/file.mpg
decodebin2的语法如下： -
gst-launch filesrc location = file.mpg ! decodebin2 ! autovideosink
