Stream LoL yourself - how it works on Twitch.tv

In this practical tip you will learn how you can stream LoL yourself on Twitch.

Stream LoL yourself on Twitch.tv: Set up Open Broadcaster software

First you need a streaming program to run a stream. The free Open Broadcaster Software (OBS), for example, is ideal for this.
After installation, open the program and carry out an update first. To do this, click on "Check for updates" in the Help menu.
When the program is up to date, open the settings menu and here the sub-item "Coding".
Depending on the quality in which you want to stream, set the "Max. Bitrate" here. The buffer size is automatically adjusted.
If you want to stream in 1080p, a bit rate of 3300 is recommended, for 720p at least 1800.
If your internet connection is not fast enough, you should provide at least 80 percent of your maximum upload speed. In a separate practical tip, we will explain how you can find out how fast your internet connection is.
Now switch to the broadcast settings. Enter "Livestream" as the mode, select Twitch as the streaming platform and Frankfurt as the FMS URL. You also need your Twitch streamkey.
You can find the streamkey on your Twitch dashboard. Click here on the far right on "Streamkey" and display your key.

League of Legends is a little bit more demanding to stream than other games because it uses different windows for the game client and the actual matches.
First of all, you have to create the appropriate scenes in the OBS. To do this, right-click in the "Scenes" window in the OBS start window. Rename the existing scene or create a new one.
You need at least two scenes: one for the character selection, the other for the actual match. Name the scenes accordingly, for example "Client" and "Game".
Usually there is also a welcome screen and a pause screen when streaming, which you can also create as individual scenes. However, these are irrelevant for the actual LoL stream.
Every scene needs a source. Therefore select "Client" and right-click in the "Sources" window. Under "Add" select the option "Window capture".
Select the LoL PVP client under "Window". Note that the client must run in parallel for this.
Then you have further setting options to adapt the window to your needs. For example, you can center it and display the client in full screen.
Now you can stream the game client. However, as soon as you start the game mode, the stream no longer updates because another window is now in focus.
Therefore you now have to set up the "Game" scene. Select a source here as well, this time as a "game recording".
Start a LoL match or watch another match to start game mode. Then you can select this as a window when setting up the scene.

When you have set up all the scenes you need, you still have to switch between them. This is usually done by hand.
This is where the plugin "Simple Scene Switcher" comes in, which OBS has now officially integrated into the program.
Open the scene change in the settings menu.
Here you select the respective window and the associated scene, for example the PVP.net Client and the scene "Pre-Game". Then click on "Add".
Note that the windows must also be available here so that they can be selected. So you have to run a game in the background so that you can assign the "League of Legends Client" to the "Game" scene.
If all scenes are in the list, you can now also set whether the scene changer should be activated automatically. You can also set a hotkey and a standard scene.
If the scene changer is activated and set correctly, you can now stream LoL without having to switch between the scenes yourself.
