changing gstreamer filter parameters on the fly, e.g. update volume or mute attribute of the gst volume filter

[r...@zcast.co]

Is there a way to change the attributes/parameters of a GST filter on the fly? E.g. I'm trying to use the volume command for a GStreamerFilter and I want to be able to read as well as update the volume on the fly.

If this is not possible, is there a way to swap a filter with another instance without causing any "break" in the stream? (say a break in the sound?)

Also looking for this answer, any hint?

So far nothing.

Have you tested to change one GStreamerFilter with another? It should work out of the box without issues.

That's the workaround, Micael. That, however, causes a short stop in the stream while the filter is exchanged. The ideal would be to update the filter parameters on the fly via API. That'd be a cool feature to have.

Yes... that'd be a cool feature. 

If you want you can implement it and make a PR.
