在 gstreamer 中复制视频以传递回管道?
我一直在尝试制作一个管道,按顺序同时具有视频混合器和 T 恤,并且我试图将视频从 T 恤循环到混音器。我希望这会像摄像机上的“b 停止”一样,但在视频上逐渐进行,因此当您在其自身上记录视频层时,会产生模糊效果,就像您在带有轨迹的星星照片中看到的那样由于曝光时间较长,随着视频的继续而积累。
我的问题是我无法说服 tee.link(mixer) 工作,并且我不知道我是否做错了什么或者我无法沿着管道将流传递回。如果有人知道为什么它不起作用,或者可以建议更好的方法,请告诉我。
I have been trying to make a pipeline that has both a videomixer then a tee, in that order, and i am trying to loop the video from the tee back round to the mixer. i was hoping this would be like a "b stop" on cameras, but progressively over the video, so as you record the video layers over itself, creating like a blur, in the sort of way you see in pictures of the stars with trails because of longer exposures, accumulating as the video goes on.
My problem is that I can not convince tee.link(mixer)
to work, and I do not know whether I am doing something wrong or that I cannot pass a stream back along the pipeline. If anyone knows why it isn't working, or can suggest a better method, please let me know.
