You can configure your account with as many input streams in RTMP and URI (HLS pull) protocols as you wish. For SRT configurations, you may reach a limit or need your Customer Success Manager to allocate endpoints on your behalf.
What counts afterwards is the number of activated signals at any point in time. This limit is set in your annual agreement with Backlight. This number might be as high as 100 concurrent streams that you can run at any one time, or as low as 5- it all depends on the contract. We do not have a technical limit to the number of streams you can run.
