Node-fluent-ffmpeg: How to add an image watermark

[seblavoie]

Version information

• fluent-ffmpeg version: 2.1.2
• ffmpeg version: 3.3
• OS: macOS 10.12.6

Code to reproduce

ffmpeg()
    .input("video-file.mov")
    .input("watermark.png")
    .complexFilter([
        "overlay=10:10"
    ])
    .videoCodec('libx264')
    .outputOptions('-pix_fmt yuv420p')

Expected results

The video should render with the watermark png onto it. There might be another way to do this. I am basically trying to do the same command from from this gist https://gist.github.com/bennylope/d5d6029fb63648582fed2367ae23cfd6.

Observed results

I get this error:

ffmpeg exited with code 1: Filtergraph 'scale=w=trunc(iw0.5/2)2:h=trunc(ih0.5/2)2' was specified through the -vf/-af/-filter option for output stream 0:0, which is fed from a complex filtergraph.
-vf/-af/-filter and -filter_complex cannot be used together for the same stream.

For those ending up here, I found the solution from this Stack Overflow answer: https://stackoverflow.com/questions/10934420/ffmpeg-how-to-scale-a-video-then-apply-a-watermark

ffmpeg()
   .input(videofile.mp4)
    .input(watermark.png)
    .videoCodec('libx264')
    .outputOptions('-pix_fmt yuv420p')
    .complexFilter([
        "[0:v]scale=640:-1[bg];[bg][1:v]overlay=W-w-10:H-h-10"
    ])
