How to make OBS Plugins for Twitch TV

Plugins should be easy to make! And for OBS, this is true. Hurray! The best way by far, my opinion, is using OBS Browser Sources. Start by trying to add a new Browser Source to your Scene. The following example shows you how to add the source.

The above shows you how to integrate a Browser Source, which is easiest way to add your custom plugin into OBS. You can set the URL to a local html file which contains your code for the plugin. The code in the HTML file may be simple or complex.

Twitch TV OBS Subtitles is a great example of what you may put into the HTML file. It's really that simple! You can have animated Cats and cat pictures that change over time. Pretty much anything you can image, just with some HTML and CSS. It's a whole new world and you can have as many cats as you like!

Modern Closed Captioning ( Subtitles )

Live TV traditionally required a human in a TV studio to transcribe spoken voice and sounds on TV. The studio transcriber's job is to listen to the live video feed and as quickly and accurately as possible type the transcription into a computer terminal which appends the closed captions directly into the Television Signal. The technical job title is a "stenographer".

During a live broadcast of a special event or of a news program, captions appear just a few seconds behind the action to show what is being said. A stenographer listens to the broadcast and types the words into a special computer program that adds the captions to the television signal.

Closed Captioning is a Slow Process

This captioning can only go as fast as a human can process information. The average reaction time of a human is is 215 milliseconds, according to the data collected so far. In addition to your reaction time, there is additional latency of your computer and the internet.

However it takes longer to determine the spoken words and then type these into a computer terminal. Your experience is seeing a delay of 4-8 seconds. Humans are creating the transcriptions, and errors are prone to happening.

Artificial Intelligence Makes Closed Captioning Easier

With advancements in Artificial Intelligence, closed captioning is becoming more efficient. AI is already automating tasks that once required human effort, like stenography. In fact, AI tools like OBS Subtitles are now handling what used to be transcriber jobs, including identifying background noises, music cues, and speakers—at no extra cost.

Why PubNub makes OBS Plugins Better

PubNub connects everything, everywhere, providing data transfer from one app to another app. In the case of the subtitles captured for Twitch TV, your web browser app is sending data to your OBS app. Essentially your computer is sending data to itself between two apps. Your voice is being transcribed in your web browser using your microphone. The resulting transcription is transmitted into the OBS Browser Source.

Imagine now you can send data directly into OBS and create entirely new online live experiences. You, or a friend, can use your an iPad to draw action lines on your live stream. You can give remote control to channel mods to manage your screen display and make minor changes. So many cool things can happen now.

PubNub can send data to anywhere. More than just sending data from one app into another app on the same computer. PubNub can send data to other computers nearby. It can even send data to computers around the world. Anywhere the internet exists, data can be transferred.

PubNub can broadcast data from one app into all other apps. Millions of apps all-at-once, and even more beyond that.
