Description

Adds OneStream Live to the service list, with our RTMPS ingest servers.

There's an Autodetect entry (live.onestream.studio, routed by GeoDNS to the closest ingest) and then one entry per location. Most locations have a Primary and a Backup server, a few only have a Primary (and Warsaw is a backup-only location).

All ingests are RTMPS on port 19350, app live. Plain RTMP on 1935 also works, but we'd prefer users connect over RTMPS. Stream keys come from the OneStream dashboard at https://app.onestream.live. Also bumped the services package version to 294.

Motivation and Context

OneStream Live (https://onestream.live) is a multistreaming and scheduling platform. A lot of our users stream from OBS and currently have to pick Custom and paste the server URL by hand. Having it in the list lets them pick a server and just paste their key.

How Has This Been Tested?

• Built on macOS (Apple Silicon, Xcode 26.2) and checked that OneStream Live shows up under Show All with the expected server list.
• Streamed from OBS to the Autodetect server and a few regional ones.
• Validated services.json against the v5 schema.
• Checked every server URL in the list accepts an RTMPS connection on 19350 with a valid certificate.

Types of changes

• New feature (non-breaking change which adds functionality)
