See the official [VideonLabs](https://www.videonlabs.com/) site for documentation, installation instructions, and additional support. ## Videon EdgeCaster ### 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): | Name | 1080p | | ----------------- | ----------------- | | Video Scaling | 1920x1080p (16:9) | | Encoding Mode | Variable Bitrate | | Video Bitrate | 5,000 kbps | | Video Encoding | H.264 (AVC) | | H.264 Profile | High Profile | | Keyframe Interval | 0.5 seconds | | Quality/Latency | Lowest | | Name | 720p | | ----------------- | ---------------- | | Video Scaling | 1280x720p (16:9) | | Encoding Mode | Variable Bitrate | | Video Bitrate | 3,000 kbps | | Video Encoding | H.264 (AVC) | | H.264 Profile | High Profile | | Keyframe Interval | 0.5 seconds | | Quality/Latency | Lowest | | Name | 360p | | ----------------- | ---------------- | | Video Scaling | 640x360p (16:9) | | Encoding Mode | Variable Bitrate | | Video Bitrate | 700 kbps | | Video Encoding | H.264 (AVC) | | H.264 Profile | High Profile | | Keyframe Interval | 0.5 seconds | | Quality/Latency | Lowest | Under **Audio Profiles**, set up your preferred audio encoding and audio bitrate settings. ![](/pr-863/assets/images/videon_audio_profiles-06e99437cd8f80a4019624dbb332ea3e.png) #### Using RTMP Open your OptiView Real-time Streaming Dashboard and copy the [**RTMP publishing paths**](https://docs-preview.optiview.dolby.com/pr-863/millicast/broadcast/rtmp-and-rtmps.md). Additionally, enable the\*\* RTMP multi-bitrate\*\* toggle. You can also use the [Multi-Source builder](https://docs-preview.optiview.dolby.com/pr-863/millicast/multi-source-builder.md) 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 OptiView RTMP dashboard. ![](/pr-863/assets/images/videon_outputs-016e7edacd98aac7d98e75214394e3b7.png) 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: | Output name | Video source | Protocol | URL | | ----------- | ------------ | --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ | | RTMP 1 | 1080p | `rtmp://` | `rtmp-auto.millicast.com:1935/v2/pub/lq30pf11?token=bcf5ffca692892ff5f861019316dd8277192698b92b08014398bfe646259c60a&sourceId=1&simulcastId` | | RTMP 2 | 720p | `rtmp://` | `rtmp-auto.millicast.com:1935/v2/pub/lq30pf11?token=bcf5ffca692892ff5f861019316dd8277192698b92b08014398bfe646259c60a&sourceId=2&simulcastId&videoOnly` | | RTMP 3 | 360p | `rtmp://` | `rtmp-auto.millicast.com:1935/v2/pub/lq30pf11?token=bcf5ffca692892ff5f861019316dd8277192698b92b08014398bfe646259c60a&sourceId=3&simulcastId&videoOnly` | ![](/pr-863/assets/images/videon-rtmp-e570fdf896c1f90bba703af194bdbe64.png) #### 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 OptiView Real-time Streaming 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](https://docs-preview.optiview.dolby.com/pr-863/millicast/multi-source-builder.md) to generate those URLs. Example: | Output name | Video source | URL | Stream ID | | ----------- | ------------ | ------------------------------------------ | ----------------------------------------------------------------------------------------- | | SRT 1 | 1080p | `srt://` `srt-auto.millicast.com` :`10000` | `lq30pf11?t=vPX_ymkokv9fhhAZMW3YJ3GSaYuSsIAUOYv-ZGJZxgo&simulcastId` | | SRT 2 | 720p | `srt://` `srt-auto.millicast.com` :`10000` | `lq30pf11?t=vPX_ymkokv9fhhAZMW3YJ3GSaYuSsIAUOYv-ZGJZxgo&sourceId=1&simulcastId&videoOnly` | | SRT 3 | 360p | `srt://` `srt-auto.millicast.com` :`10000` | `lq30pf11?t=vPX_ymkokv9fhhAZMW3YJ3GSaYuSsIAUOYv-ZGJZxgo&sourceId=2&simulcastId&videoOnly` | ![](/pr-863/assets/images/videon-srt-9d90553f6038dcc545c375d16855e838.png) ### How-to apply a multi-viewer with Videon EdgeCaster You can also use the [Multi-Source builder](https://docs-preview.optiview.dolby.com/pr-863/millicast/multi-source-builder.md) to generate the URLs. For information on Simulcast, refer to [the documentation](https://docs-preview.optiview.dolby.com/pr-863/millicast/distribution/using-webrtc-simulcast.md) 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: | Encoder | Source name | Protocol | URL | | ------------ | ----------- | --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ | | EdgeCaster 1 | Main | `rtmp://` | `rtmp-auto.millicast.com:1935/v2/pub/lq30pf11?token=bcf5ffca692892ff5f861019316dd8277192698b92b08014398bfe646259c60a&sourceId=1&simulcastId` | | EdgeCaster 2 | Backstage | `rtmp://` | `rtmp-auto.millicast.com:1935/v2/pub/lq30pf11?token=bcf5ffca692892ff5f861019316dd8277192698b92b08014398bfe646259c60a&sourceId=2&simulcastId=Backstage` | | EdgeCaster 3 | VIP | `rtmp://` | `rtmp-auto.millicast.com:1935/v2/pub/lq30pf11?token=bcf5ffca692892ff5f861019316dd8277192698b92b08014398bfe646259c60a&sourceId=3&simulcastId=VIP` | 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.
