How-to use multi-bitrate on Videon EdgeCaster

Inside the Videon web UI, under Video Profiles, create three profiles of distinct bitrate (1080p, 720p, 360p):

Under Audio Profiles, set up your preferred audio encoding and audio bitrate settings.

Using RTMP

Open your Dolby.io dashboard and copy the RTMP publishing paths. Additionally, enable the RTMP multi-bitrate toggle. You can also use the Multi-Source builder to generate those URLs.

Under Outputs, for each RTMP, select Video Source corresponding to the RTMP profile (1080p for the highest profile and 360p for the lowest profile). Make sure to set Streaming Providers to Generic RTMP and paste the Stream URL from the Dolby.io RTMP dashboard.

For the Stream URL, combine the RTMP publish path (use RTMPS publish path and select rtmps:// if you prefer to publish to an RTMPS endpoint), with the RTMP multibitrate corresponding value: High for RTMP 1, Medium for RTMP 2, and Low for RTMP 3.

Example:

Using SRT

Under Outputs, for each SRT, select Video Source corresponding to the SRT profile (1080p for the highest profile and 360p for the lowest profile). For the URL, select the srt:// protocol, enter the URL of the SRT publish path from the Dolby.io dashboard, and enter port 10000. For the Stream ID, use the SRT stream ID from the dashboard and append &simulcastId for the first layer, &sourceId=1&simulcastId&videoOnly for the second layer, and &sourceId=2&simulcastId&videoOnly for the third layer. You can also use the Multi-Source builder to generate those URLs.

You can also use the Multi-Source builder to generate the URLs. For information on Simulcast, refer to the documentation to understand its usage.

Using RTMP

To enable the multi-view, add this to the end of your stream URL, add the sourceId parameter with a unique value. Example: &sourceId=1. The name of your source will be set using the simulcastId parameter. Your main source does not need a value for this parameter so leave it empty &simulcastId. Your other feeds must be defined as &simulcastId=SourceName.

Example:

If you are combining multi-view and multi-bitrate, for each source, usually only the first layer contains the audio track, so for the other layers, add the parameter &videoOnly to the Stream URL.
