You can now use the "kululuLIVE Browser Encoder", which allows you to stream using only a browser, without the need for streaming software such as OBS.
It will now be possible to stream on ChromeOS (Chromebooks, GIGA school devices, etc.), which was previously impossible to do no matter how hard you tried.
Of course, it can also be used on Windows, MacOS, smartphones and tablets, and can also be used by people who cannot use OBS or apps for religious reasons.
Obtain a streaming slot and open "Browser Encoder" from the menu.
In the opened browser encoder, click "Start Push Connection".
Once you have properly granted browser permissions, you will be presented with a screen to select your audio and video devices.
Select Camera if you want to broadcast the real world using your device's camera, or select "Capture screen" if you want to broadcast your device's screen.
*Due to the specifications of the OS, "Capture Screen" cannot be used on mobile devices. Images can only be captured by the camera. If you want to use "Capture Screen", please use the app version.
*If you select screen capture and microphone, the stereo mixer function will mix the sound from the microphone and the sound played on your device.
The push connection will start automatically. After that, you can switch to public streaming as usual.
The kukuluLIVE Overlay will be automatically composited into the broadcast video, and if you enable overlays such as comments, they will be composited into the broadcast video.
No additional settings are required like with OBS.

On mobile devices such as smartphones and tablets, comments will be displayed in the bottom half of the screen, just like the app version.
You can use the read aloud function in the comment section settings.
As with the app version, video and audio will not be sent unless the browser encoder is in the foreground, but unlike the app version, the push will not be cut off immediately.
Unlike a normal push connection, the browser encoder connects to a server-side encoder using WebRTC (WHIP).
The server converts the RTMP to HEVC and then pushes it.
This makes it less likely for the connection to be lost, even in environments with unstable specifications or lines and frequent frame drops.
RTMP will disconnect after 13 seconds of inactivity, but WHIP will tolerate up to 3 minutes.
・If you are pushing content on the go via a PC or dedicated distribution device, it may be possible to replace it with this browser encoder.
・kukuluLIVE Overlay can be used even in mobile environments.
・You can connect using the same URL even if the distribution slot changes.
