Three ways to multistream
| Method | How it works | Trade-off |
|---|---|---|
| Direct, from your PC | Your software sends the stream to each platform's server | Needs upload for every destination; no middleman; you control quality |
| Relay service | You send one stream to a service that forwards it to every platform | Only one upload from you; the service may be paid and adds a dependency |
| Several encodes | One encode per platform with different settings | Allows per-platform quality, but costs more encoder work |
Do the upload sums first
If you send a 6 Mbps stream directly to three platforms, you need about 18 Mbps of upload plus margin. A relay service needs only the single 6 Mbps. Measure your real upload speed before choosing a method, and leave headroom: a connection that is exactly enough will drop frames.
How BriseStream handles it
- Several destinations can run at once. A destination's address chooses its protocol:
rtmp://orrtmps://,srt://, andhttps://for WHIP. - Destinations with identical video settings share one encoder; different codecs open a second encoder session.
- Each destination has its own statistics and switch in the health panel while you are live.
- A destination that drops reconnects automatically with exponential backoff, and a recording goes on while the network is down.
- When the upload saturates, the bitrate controller lowers the stream's bitrate and warns you rather than dropping frames silently.
Platforms differ on codecs and rules. In the project's notes of November 2026, Twitch and Kick accept H.264 only over RTMP. Check each platform's current terms before multistreaming.
Questions and answers
Can I stream to Twitch and YouTube at the same time for free?
Technically yes, if your software supports several destinations and your upload is large enough. BriseStream is free and supports several destinations; it is still in development and has no public release yet.
How much upload do I need to multistream?
Roughly the bitrate of one stream multiplied by the number of destinations you send directly, plus margin. A relay service reduces it to one stream.
Does multistreaming cost more FPS?
Destinations with the same settings share one encode, so extra destinations mainly cost upload bandwidth. A different codec or resolution opens another encoder session.
