You can live stream content without a capture card if you are viewing that content on the same machine you wish to stream from. Say for example you’re playing a PC game and you want to stream it on Twitch. You can use live streaming software such as OBS to capture your gameplay and send it to your audience without any extra hardware. However, if you’re playing a game on the PlayStation 5, this is an external device, so the process is different. If you want to live stream from a console or other external device, you will have to use the device’s built-in live streaming tools or get a capture card to send the video feed to your computer. From there, you can manage and edit the feed from the capture card on your computer in your live streaming software and beam it to your audience.
