GStreamer:播放mpeg2 [英] GStreamer: Play mpeg2

问题描述

我正在尝试使用gstreamer播放本地mpeg2 TS文件:

I'm trying to play a local mpeg2 TS file with gstreamer with this:

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

第一帧显示为大块彩色，然后停止.对我在这里做错什么有任何想法吗? -TS文件的处理方式是否与此不同?

The first frame appears as big blocks of color and then stops. Any thoughts about what I'm doing wrong here? Does a -TS file need to be handled differently than this?

这是日志:

$ gst-launch  filesrc location=open_season.mpg ! mpeg2dec ! xvimagesink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ....

推荐答案

我认为首先您应该首先尝试在playbin2的帮助下播放文件.如果您能够播放它，那么您应该使用encodebin2，调试其输出并相应地构建您的管道.

I think first you should first try to play the file with the help of playbin2. If you are able to play it then u should use decodebin2 ,debug its output and construct your pipeline accordingly.

playbin2的语法如下:-

The syntax for playbin2 is as follows :-

gst-launch playbin2 uri = file:///home/user1031040/Desktop/file.mpg

decodebin2的语法如下:-

The syntax for decodebin2 is as follows:-

gst-launch filesrc location = file.mpg ! decodebin2 ! autovideosink
