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

第一帧显示为大块色块，然后停止。关于我在这里做错了什么有什么想法吗？是否需要以不同方式处理 -TS 文件？

这是日志：

$ gst-launch  filesrc location=open_season.mpg ! mpeg2dec ! xvimagesink

我认为首先你应该首先尝试在 playbin2 的帮助下播放文件。如果您能够播放它，那么您应该使用 decodebin2 ，调试它的输出并相应地构建您的管道。

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
