Element for blocking the data - Like Valve

[Baby Octopus]

Hi,

Is there an element to block the data and release the data dynamically to the pipeline, something like valve, which can be configured via property?

Not sure what you mean with this. The valve state is configurable via property using the "drop" property.

Do you want to block the pipeline rather than drop the frames? Unfortunately I am not aware of a variant like that.

A solution, albeit not an answer to your exact question is to use a probe to block the pipeline.

What would be the criteria for blocking and releasing?

Yes, blocking and releasing to be based on property, juts like blocking and dropping is based on valve's property

May be its not too difficult to create an element. Was wondering if any such element already exists

If you know how long you want to block and release for, you can do it with a queue by changing the min-threshold parameter

That would not really block, though - it would just queue up data until the threshold is reached or changed.

The difference is that by using queue, upstream is still actively pushing, while with a probe, upstream too gets blocked.
