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

我可以像这样使用 gstreamer 的 gst-launch 在命令行上播放视频:

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

这会播放/tmp/myfile.mov 中文件的前 2 秒，之后视频播放停止.有没有办法让它重复循环?即将 2 秒长的 gnlfilesource 变成无限长的视频，一遍又一遍地播放那 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...

将其包裹在 while 循环中?

Wrap it in a while-loop?

while true; do [your command]; done

其中 true 什么都不做，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...
...
