Plugin black image

Hello, i was testing 

 

2. Overlay Filter:

You can use an overlay filter to add a stream over another one as an overlay.

curl command:

curl -i -X POST -H "Accept: Application/json" -H "Content-Type: application/json" "http://localhost:5080/WebRTCAppEE/rest/v2/filters/create" -d '{"filterId":"overlaydemo","inputStreams":["stream1","stream2"],"outputStreams":["test"],"videoFilter":"[in0]scale=240:160[s0];[in1][s0]overlay[out0]","audioFilter":"[in0][in1]amix=inputs=2[out0]","videoEnabled":"true","audioEnabled":"true","type":"asynchronous"}'

Input streams: stream1 and stream2

Output streams: test

Video Filter Text:
[in0]scale=240:160[s0];[in1][s0]overlay[out0]","audioFilter":"[in0][in1]amix=inputs=2[out0]

Explanation: We scale stream1(in0) to 240×160 and obtain a hidden stream(s0). The we apply it to the stream2(in1) and obtain the output stream test(out0).

Output:

 

but not working for me version 2.4.1

i get stream black.

 

So question is:

 

here say we have to inputs Stream 1 and stream 2 and the output stream name test

{"filterId":"overlaydemo","inputStreams":["stream1","stream2"],"outputStreams":["test"]

 

So the output here we create or should be existing one.

input streams are i guess from where we get the video to insert in the output , or not?

Also if i want to rewrite means

i already create output test then i want to add another filter on same output test? without loosing transmition.

Hi @robertosamayoa,
First you don't have to have a stream with the id of output stream, it will be created automatically.

Also do you have the input streams available when you called the REST method?

Could you please send me the filter text you send?

 

[robertosamayoa]

i was able to test plugin option, making testing i saw the issue here is,

 

if we get input sources A and B we also have to create an output stream, the problem here is we want to apply new plugin to same outpout stream is not possible, as we have to delete current and create new, and doing that is a new stream.

 

get it? or i am wrong?

Using source A and source B, you can update the existing plugin output stream without creating a new one. Here's a postman Curl sample:

curl --location --request PUT 'https://domain-name:port/LiveApp/rest/v2/filters/mcu-filter' \
--header 'Accept: Application/json' \
--header 'Content-Type: application/json' \
--data '{"filterId":"overlay","inputStreams":["sourceA","sourceB"],"outputStreams":["output"],"videoFilter":"[in0]scale=240:160[s0];[in1][s0]overlay[out0]","audioFilter":"[in0][in1]amix=inputs=2[out0]","type":"asynchronous","videoEnabled":true,"audioEnabled":true}'

For example, I used the overlay filter. You can use different filters depending on your needs.

I hope it helps.

also when i update the same filter not start playing not even if refresh. i am testing playing streams on DASH.

example

 

1./ Put first api

2./ Put second api

and keep changing, will see 

 

example

curl --location --request PUT 'https://domain:5443/WebRTCAppEE/rest/v2/filters/mcu-filter' \
--header 'Accept: Application/json' \
--header 'Content-Type: application/json' \
--data '{"filterId":"overlay3","inputStreams":["stream1","stream2"],"outputStreams":["hellomundo"],"videoFilter":"[in0]scale=534:354:force_original_aspect_ratio=decrease,pad=720:360:93:3:color=black[s0];[in1]scale=174:114:force_original_aspect_ratio=decrease,pad=720:120:273:3:color=black[s1];[s0][s1]vstack=inputs=2,pad=720:480:0:0[out0]","audioFilter":"[in0][in1]amix=inputs=2[out0]","type":"asynchronous","videoEnabled":true,"audioEnabled":true}'
 

 

curl --location --request PUT 'https://domain:5443/WebRTCAppEE/rest/v2/filters/mcu-filter' \
--header 'Accept: Application/json' \
--header 'Content-Type: application/json' \
--data '{"filterId":"overlay3","inputStreams":["stream2","stream1"],"outputStreams":["hellomundo"],"videoFilter":"[in0]scale=240:160[s0];[in1][s0]overlay[out0]","audioFilter":"[in0][in1]amix=inputs=2[out0]","type":"asynchronous","videoEnabled":true,"audioEnabled":true}'
