FFMPEG filters provide a powerful way to programmatically enhance or alter videos, and it’s fairly simple to add a watermark to a video using the overlay filter. The easiest way to install ffmpeg is to download a pre-built binary for your specific platform. Then you don’t have to worry about including and installing all the right dependencies and codecs you will be using.
Once you have ffmpeg installed, adding a watermark is as easy as passing your existing source through an overlay filter like so:
ffmpeg -i test.mp4 -i watermark.png -filter_complex "overlay=10:10" test1.mp4
Basically, we’re passing in the original video, and an overlay image as inputs, then passing it through the filter, and saving the output as test1.mp4.

For users who prefer working with a command line or need to access advanced encoding settings for Hap the popular FFmpeg library can be used to work with Hap movies.
If this is your first time using FFmpeg you may need to install it on your system, or compile it from source. In either case be sure that Snappy is enabled as part of the binary. If you already have FFmpeg on your system with Snappy enabled, you can skip this step.
You can check that your version of FFmpeg can encode Hap using
ffmpeg -encoders | grep hap

| Setup: | |
| 1. Index buffer containing N quads (each 2 triangles), where N is the max amount of spheres. Repeating pattern of {0,1,2,1,3,2} + K*4. | |
| 2. No vertex buffer. | |
| Render N*2 triangles, where N is the number of spheres you have. | |
| Vertex shader: | |
| 1. Sphere index = N/4 (N = SV_VertexId) | |
| 2. Quad coord: Q = float2(N%2, (N%4)/2) * 2.0 - 1.0 | |
| 3. Transform sphere center -> pos |
