Watermarking on existing video

Question

I'm looking for a method to watermarking on a video with C#.

As writing text on it.

Image or text label...

How can I do it? Thanks.

Answer 1

You can use Nreco Video Converter

The Code will look like

NReco.VideoConverter.FFMpegConverter wrap = new FFMpegConverter();
wrap.Invoke("-i D:\\input.mp4 -i D:\\inputImage.png -filter_complex \"overlay=10:10\" D:\\Output.mp4");

What about the great framework from AForge?

Answer 3

The great people at Splicer for .Net have already developed some C# code that does what you are looking for, but unfortunately I have heard that it takes a while to complete.

At least this can serve as a starting point if nothing else
