    Default [ Add filter on video stream ]

    Hello,

    I'm new here & I wanted to know if it's possible to add a "Blur filter" to a video stream ?

    I saw that we can reduce the quality of a Stream with the transcoder but I want to add filter, to blur completely a video stream, is that possible with wowza (server-side) ?

    Thanks

    Hello there and welcome to the Wowza support forum.

    The feature you are looking for is not available with the current version of Wowza. Not sure if it will be in the future or not.

    An alternative might be to add an image overlay to the stream:

    Also, you might be able to do this at the encoder. Depending on the encoder you are using. You can do it via FFMPEG, possibly Wirecast.

    I hope this is helpful.

    Kind regards,

    Salvadore

    A sample ffmpeg command would be something like this:
     -i sample.mp4 -vf "boxblur=enable='between(t,0,113)'" -codec:a copy -f flv rtmp://[wowza-ip]:1935/live/myStream
     0,113 (start/end)
