AW: Using the valve plugin correctly in a gstreamer pipeline

[Thornton, Keith]

Hi,
I gave up using valve because it blocks events as well as buffers (you won't get EOS). If you use valve you have to set drop to false at the start and then when the pipeline has prerolled you can set it to true. However I would recommend using pad probes instead. You have much finer control over your pipeline. Sebastian has written a good guide if you google dynamic pipelines.
Grüße

Betreff: Using the valve plugin correctly in a gstreamer pipeline

I am trying to use the `valve` plugin to basically block one branch of a `tee` in a gstreamer pipeline but this is setting my whole pipeline to `PAUSED`. So, what I am doing is basically saving H264 encoded video from my camera stream and also displaying it on the screen at the same time.

I try to use the `valve` plugin to block off a branch as follows;



However, this basically seems to set the whole pipeline to PAUSED rather than just the branch. I was still expecting to see the camera stream on the display but that is not the case.
