Work in Progress – Japanese Translation

I’ll be translating some of these into Japanese (which will require revising the original English writings). Part of this is being done since there aren’t a lot of these guides in Japanese (because Twitch is not a large streaming platform in Japan). これらのうちいくつかを日本語に翻訳します（そのため元の英語文章を改訂する必要があります）。その一因として、日本語でのガイドがあまり存在しないことが挙げられます（Twitchが日本では大きな配信プラットフォームではないためです）。

Local SRT Streaming Setup: IRL Pro, Moblin, OBS

This is a simple internal (wired/wireless LAN) SRT streaming setup between a smart phone (Android or iPhone) and OBS (PC or Mac) which is useful for using them as camera sources without having to rely on something like VDO.ninja. While there is nothing wrong with VDO.ninja per se (it utilizes WebRTC), the initial setup does require going through their site (after that portion is established, connections are peer-to-peer). By comparison, this setup is under your complete control internally from start to finish and is also useful for setting up an actual OBS relay for IRL streaming (where there are more...

Travel/IRL Gadget Backpack (Work-in-Progress DRAFT)

This is a work-in-progress draft (I also don’t do any sponsorships/monetize anything so nothing in this writeup is sponsored). Travel/IRL backpack, cable/power management test build (I already have tested quality braided USB-C cables that can handle 100W of charging/data transfer via a 5Gbps USB-C hub with 100W passthrough charging/power delivery (to trickle charge a phone, tablet, vlogging camera, DSLR, stabilizer, etc) and power a peltier cooler). The premise is to have an organized system (for my DSLR, tablet/laptop/devices) with secured cable management (quality braided cables that can handle both 65+W of power and USB 3.0 transfer speeds) alongside an easy...

iPad/iPhone Screen Mirroring to Windows PC via AirDroid Cast

Background: AirDroid Cast (the free version) allows wireless screen mirroring from a mobile device (Android, iOS, iPadOS) to a Mac or Windows PC (the paid version enables other options like Apple’s AirPlay and USB). Both mobile and desktop need to be running the application for each respective platform. This tutorial is specifically for iPad/iPhone screen mirroring to a Windows PC (iPad/iPhone’s can stream natively to any AirPlay device including Mac’s running at least macOS 12 Monterey). Testing Note: I ran this setup for several hours streaming audio/video without any crashes or frame rate drops (my PC is connected via Cat6...

Moblin Picture-in-Picture Multi-camera

This is pretty simple to setup. It involves creating a new scene and new widget (in OBS terminology, this is like adding another source to your scene). The main scene is going to be the rear (outside) camera while the widget will be the front (inside) camera. The low power rear/outside camera source is what needs to be selected for the main Picture-in-Picture scene with this multi-camera setup. 1. Tap Settings, then Scenes. Create a new scene and name it to whatever you want (in this example, I am using “PIP2”). 2. Select your video source. This again is going...

Multistreaming via OBS

This is a work-in-progress… Multistreaming (aka multicasting) is simply being able to stream to different platforms simultaneously. Note that each specific platform has their own requirements (to qualify for live streaming). None of that will be covered here. As for the how, there are different ways to achieve this, each with their positives and negatives. Restream.io The free version of Restream.io allows streaming to two platforms (paid allows streaming to 30+ platforms simultaneously); OBS is reconfigured to stream directly to Restream (where you setup your Twitch and YouTube stream key info). While it’s not my preference because it is now...

Streamer.bot Twitch Clip to Discord Action Import String

The following is a Streamer.bot action script that can be imported and modified to perform a Twitch clip (30 seconds) from chat (!clip) and have the URL posted to a channel on Discord. The 30 seconds is a Twitch API restriction. The channel owner will have the ability to go and manually edit these clips using the Twitch clip tool where its length can be longer (before and after the stream marker) and titles can be changed (another Twitch API restriction is that the clip title will match the name of the stream title). In the Discord Basic Webhook sub-action...

Gimbal/Stabilizer versus Tripod Stick

There are a lot of wide ranging thoughts/opinions regarding whether or not gimbals/stabilizers (I will use these terms interchangeably) for ones smartphone are a high priority piece of equipment for IRL streaming compared to a tripod-style selfie stick. Gimbals utilize motors (gyroscopes) to stabilize the motion and allow for smooth tracking and panning. Thus it seems like it would be a natural fit for IRL live streamers. The reality is it depends highly on the equipment and actual situational use cases. Older stabilizers were large/bulky because they were designed with large motors. They were great for capturing really smooth footage...

Screenshot Twitch Stream to Discord via Streamer.bot and OBS

This tutorial is for a channel point redeem that takes a screenshot of a camera source (raw) from a selected scene in OBS Studio (using Streamer.bot), which is then posted into a channel on Discord.  Capturing a screenshot with all of the overlays is slightly more complicated requiring referencing a previously defined scene (and is not covered).  Similarly, an on-stream visual/sound effect are also not covered. An importable action script is located at the bottom (though I recommend also reading through this to see how the script actually works). Please see the note in Step 6 regarding the security considerations...

Sidekick Clip Shoutout

Overlay for OBS that plays back clip from a channel (allows you to shoutout video clips from a Twitch channel).  Note that this used to exist at efuse.gg/sidekick but is now located at the linked site.  Prior overlays/settings were not migrated over to the new site (but may still be running on the prior site). It’s a standard browser source overlay for OBS that is configurable. Step 1: Create an account and sign in (old efuse.gg accounts still work; you will just need to link your streaming platform account).  Some of the following screenshots do not match the newer setup...

Sun Microsystems Stuff

Sun Microsystems (in the 90’s which was wild due to the dot.com bubble) was a great learning experience (as a systems engineer).  Most of what I did was on Sun-4c (SPARC) aka SPARCstation and SPARCserver, Sun-4u (Ultra SPARC) and SunOS 4.1.x (aka Solaris 1.1.x).  Lot of the workstation and enterprise hardware was built like tanks. The following folder are some of the Solaris 7 datasheets (after I’d left). Google Drive I still have my SPARCstation IPX (SunOS 4.1.4) It’s still funny looking back at what are now crude digital images (from the lousy 90’s era digital cameras that existed at...
