Add watermark using plugin

[Цэрэнчимэд Цэгмид]

Hello. I am trying to add watermark on RTMP stream on Ant media EE.

I know there is no built in feature on that and i want to accomplish using plugins. 

Is it possible?

And is there any guide about using plugin. I checked sample plugin, but that code is not clear.

Hi,

Actually you can do it with built-in filter plugin in v2.4.0.2

You should do  followings:

1. Add an adaptive bitrate setting 

2. Copy the logo image somewhere in server

3. Call Create filter REST method as:

curl -i -X POST -H "Accept: Application/json" -H "Content-Type: application/json" "https://your_domain:5443/APP_NAME/rest/v2/filters/create" -d '{"inputStreams":["stream_name"],"outputStreams":["stream_name"],"videoFilter":"movie=/path/to/your/image.png,scale=100:100[logo];[in0][logo]overlay[out0]","audioFilter":"[in0]acopy[out0]","videoEnabled":"true","audioEnabled":"true","type":"synchronous"}'

Then the logo will be added your stream.

Thank you for your answer. 

is There any documentation of this plugin? I could not find anything.

You may check this:

https://github.com/ant-media/Plugins/tree/master/FilterPlugin#filter-usage

But the documentation isn't mature yet.

You may also check from source:

https://github.com/ant-media/Plugins/blob/master/FilterPlugin/src/main/java/io/antmedia/rest/FilterRestService.java

Hi, if adding logo and restreaming logo will display on other networks or just on ams.

Watermarks are usually composited into the video and not just superficially overlayed. So the output should  contains the logo irrespective of where it is transmitted to and should also appear on recordings.

@Burak@Connessione  Can You Please tell me how can we achieved to display user uploaded watermark on their streaming or can we set watermark position

[usama]

yes you can archive it using filter plugin please take a look at https://antmedia.io/discover-the-filter-plugin/ 

search for  Movie Filter and Adding Logo. But please keep in mind that this is CPU hungry task

[yogesh jain]

@usama where is any option for set logo position because it shown left-top corner i want right-bottom corner.

[yogesh jain]

or is there any solution which does not affect cpu. 

[usama]

curl -i -X POST -H "Accept: Application/json" -H "Content-Type: application/json" "http://localhost:5080/WebRTCAppEE/rest/v2/filters/create" -d '{"filterId":"logodemo","inputStreams":["stream1"],"outputStreams":["test"],"videoFilter":"movie=/home/burak/antmedia.png[logo];[in0][logo]overlay=main_w-overlay_w-10:main_h-overlay_h-10[out0]","audioFilter":"[in0]acopy[out0]","videoEnabled":"true","audioEnabled":"true","type":"asynchronous"}'

If your viewers are on web , you can do it on client side as well.then it would not take any cpu usage on server side.

[yogesh jain]

[yogesh jain]

@usama when we call this post api we pass image path can we pass url in replace of path. so we add custom watermark from users. because how to upload user watermark on our ant media server

Edited April 5 by yogesh jain

[usama]

I think you will have to develop a image file uploading service on your back end and upload the file to your server and save it in a directory. because ant media does not have any API to upload a image file
