How to remove audio using the filter plugin?

[timantmedia]

I am trying to use the filter plugin to create a new stream where the audio is removed.

This is the API request I am using:

curl -i -X POST -H "Accept: Application/json" -H "Content-Type: application/json" "http://localhost:5080/LiveApp/rest/v2/filters/create" -d '{"filterId":"filter1","inputStreams":["stream1"],"outputStreams":["stream2"],"videoFilter":"[in0]acopy[out0]","audioFilter":"[in0]acopy[out0]","videoEnabled":"true","audioEnabled":"false"}'

However, I get an error:

{"success":false,"message":"Video filter graph can not be initiated:[in0]acopy[out0]","dataId":null,"errorId":0}%

I just copied the request from the blog post here https://antmedia.io/discover-the-filter-plugin/ that is used to flip the video using vflip but I replaced vflip with acopy.

@USAMAWIZARD Actually, I tried it again on a new installation and it worked. I used the sample request on this post
that flips the video. My problem is how to not flip video. I tried chaning vflip to acopy but it errors.

This causes an error

"videoFilter":"[in0]acopy[out0]"

So what I tried is this but errors:

curl -i -X POST -H "Accept: Application/json" -H "Content-Type: application/json" "http://localhost:5080/WebRTCAppEE/rest/v2/filters/create" -d '{"filterId":"filter1","inputStreams":["stream1"],"outputStreams":["test"],"videoFilter":"[in0]acopy[out0]","audioFilter":"[in0]acopy[out0]","videoEnabled":"true","audioEnabled":"false"}'
