Filter behavior on "openvidu-android"

Hello

I’m trying to implement the filter feature in “openvidu-android” in “tutorials”.

I have set the following, but it does not work properly.

public void publishVideo(SessionDescription sessionDescription) {
Map<String, String> publishVideoParams = new HashMap<>();
publishVideoParams.put(“audioActive”, “true”);
publishVideoParams.put(“videoActive”, “true”);

publishVideoParams.put(“filter”, “{"type":"GStreamerFilter","options":{"command":"videoflip method=vertical-flip"}}”); //<-- add

Is there any other way?

Please help me, thank you.

I haven’t solved it yet.
