THEOlive offers some pre-configurations for different types of streams. This allows you to adjust the stream settings according to your use case.
Depending on the resolution you choose, your ABR ladder will exist out of four steps (in case of 1080p), three steps (in case of 720p), two steps (in case of 480p), or one step (in case of 360p).
When configuring your RTMP ingest, it is important to match the highest bitrate of your bitrate ladder. When using the recommended preset at 1080p for example, the RTMP ingest should be configured at 4000 kbps.
The default configuration that will work for most use cases.
|HD - 1080p||4000 kbps|
|HQ - 720p||2500 kbps|
|MQ - 480p||1200 kbps|
|LQ - 360p||900 kbps|
The ideal configuration for streams with fast-moving images and a lot of scene changes that have a high bit rate. An example can be a broadcasted football game.
|HD - 1080p||4500 kbps|
|HQ - 720p||2700 kbps|
|MQ - 480p||1400 kbps|
|LQ - 360p||1000 kbps|
The configuration that can be used when not a lot of scene changes are expected, think about a meeting with a few slides.
|HD - 1080p||2200 kbps|
|HQ - 720p||900 kbps|
|MQ - 480p||800 kbps|
|LQ - 360p||450 kbps|
To obtain the best performance, set the same frame rate on both your encoder and in the channel configuration (the suggested values for this are 25, 29.97 or 30 fps). Frame rate differences between encoder and channel may lead to information loss and stalls.
Make sure your encoder has a stable connection with enough upload bandwidth to correctly serve all frames. Dropped frames or connection interruptions may lead to increased latency, stalls and playback failures.
