To remove a submodule you need to:
class PostIndex extends React.Component { | |
state = { loading: false }; | |
componentDidMount() { | |
window.onscroll = () => { | |
if (!this.state.loading | |
&& (window.innerHeight + window.scrollY) | |
>= document.body.offsetHeight) { | |
this.setState({loading: true}, () => { |
var Index = React.createClass({ | |
getInitialState: function () { | |
return { | |
lastPress: 0 | |
} | |
}, | |
onPress: function () { | |
var delta = new Date().getTime() - this.state.lastPress; |
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.

# batch resize @3x iOS image assets to @2x and @1x | |
# copy this script to the folder where the @3x images files live and run "./resizer3x.sh" in terminal. | |
# this will generate [filename]@2x.[extension] and [filename].[extension] images in the same folder | |
# Ensure we're running in location of script. | |
