issue with watermark application via transcoder on a VOD stream

[jainam]

I’m facing an issue with watermark application via transcoder on a VOD stream:

The watermark only appears on the transcoder stream , Previously (or as I expected), it was showing directly in the original video stream as well, or I could view the VOD stream with watermark.

How can I make the watermark visible directly in the original VOD stream without switching to the transcoder stream?

Good day.

How can I make the watermark visible directly in the original VOD stream without switching to the transcoder stream?

Watermark may be applied to the transcoded stream only. It can't be applied to an original stream. Please read the docs:

This is my step to implement stream and transcoder


First, I start the stream using the rest-api/vod/startup API with the following parameters:
{
"uri" : "vod-live://bg.mp4",
"localStreamName" : "Test",
"loop" : true
}
This runs bg.mp4 in a loop under the stream name Test.


Next, I start the transcoder using rest-api/transcoder/startup, where Test is the remote stream and Test_with_watermark is the local stream. I set the encoding parameters as follows:

{
"uri":"transcoder://Test_tcode1",
"remoteStreamName":"Test",
"localStreamName":"Test_with_watermark",
"encoder": {
"width": 640,
"height": 480,
"keyFrameInterval": 30,
"fps": 30
}
}

After that, I apply a watermark using rest-api/transcoder/set_watermark, setting the watermark image and positioning it as follows:
{
"uri":"transcoder://Test_tcode1",
"watermark":"/media/13983.png",
"x":10,
"y":10,
"marginTop":5,
"marginLeft":5,
"marginBottom":5,
"marginRight":5
}



Previously, the watermark appeared on both the main stream (Test) and the transcoded stream (Test_with_watermark). However, now it only appears in Test_with_watermark, and the main stream (Test) remains unmodified.

This change happened around 10-15 days ago. I would like to know if there has been any recent change in Flashphoner’s behavior regarding watermarking .
and if there is a way to make the watermark visible in the main stream (Test), as it was before.

It was the bug. The watermark must be applied to transcoder output stream, not to the transcoder source stream.
The bug was fixed, so you should change your flow: a viewers should play transcoder output stream, but not the original stream.

is there any way to apply the watermark directly to the main (source) stream?

You must decode the stream to apply watermark at server side. For example:
1. Set the following parameter in falshphoner.properties

custom_watermark_filename=/media/13983.png

2. Play the stream with resolution set explicitly
In this case the stream will be transcoded to the resolution set, and watermark will be applied for all the viewers.
You can also apply watermark at publisher client side using HTML5 canvas. In this case, you draw watermark over the captured picture in browser.
