使用gstreamer和gst-launch循环播放视频? [英] Looping a video with gstreamer and gst-launch?

问题描述

我可以使用gstreamer的gst-launch在命令行上播放视频，如下所示:

I am able to play a video on the command line with gstreamer's gst-launch like this:

gst-launch gnlfilesource location=file:///tmp/myfile.mov start=0 duration=2000000000 ! autovideosink

这将播放/tmp/myfile.mov中文件的前2秒，然后视频播放停止.无论如何，有没有让它反复循环?即将2秒长的gnlfilesource变成无限长的视频，可以一次又一次地播放那2秒?

This plays the first 2 seconds of the file in /tmp/myfile.mov, afterwards the video playback stops. Is there anyway to get this to loop repeatidly? i.e. turn the 2 second long gnlfilesource into an infinite length video that plays those 2 seconds again and again and again?

推荐答案

假设bash ...

Assuming bash...

将其包裹在while循环中?

while true; do [your command]; done

其中true不能成功执行任何操作，即

where true does nothing sucessfully, i.e.

true: true
    Return a successful result.

    Exit Status:
    Always succeeds.

它允许您创建无限循环，例如

It allows you to create infinite loops, e.g.

$ while true; do echo "run..."; sleep 1; done
run...
run...
run...
run...
run...
...
