Since PC based broadcasting software has improved so much over the past year, we no longer recommend studios spend the time integrating game streaming directly into their PC game clients. Instead, we recommend studios to encourage their userbases to download third party broadcast solutions such as OBS, and promote their streaming community within their game with in-game viewing integrations and through all other communication channels such as social media and email.
Third party broadcast software such as OBS do not rely on the SDK and will be unaffected.
Also just to be clear, while we won't be offering the PC SDK for new integrations, we will continue to support existing integrations. Also if you have a unique/creative idea for an integration we would still like to hear from you.
