How to Add a Watermark to Video

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.

val nested = spannable{ bold(italic("nested ")) + url("www.google.com", "text") }

val noWrapping = bold("no ") + sub("wrapping ) + sup("also ") + "works"

text_view.text = spanned + nested + noWrapping

Example of using RxJava to listen to connectivity status in Android

You could use the same approach to listen to any status, but this example includes network connectivity specifics too (ConnectionChangeReceiver and AndroidUtils.isConnected).
