Haivision KB
To get started, log into your Dolby OptiView dashboard. Enter your KB web interface, switch views to the Channel Control Center, and create a new channel.
Follow the Create Channel Wizard prompts to create a channel as normal:
- Enter the desired channel name.
- Identify your live source for the channel input.
- Choose RTMP for the channel output and copy the RTMP publish path from the Dolby channel you have created.
RTMP URL:rtmps://rtmp.<my-channel-region>.hesp.live/live - Enter the RTMP publish stream name from the ingest server section.
Stream Name:<my-stream-key>
With the broadcast credentials set up, the stream is ready to go live. To view the stream, scroll down to the Playout configurations section in your channel page and start the player.
Recommended settings
Here are some adjustments recommended by the Haivision support team:
| Settings Location | Recommendation |
|---|---|
| In Input settings | Change Timestamps from System Time to Zero-Based* |
| In Video Encoder settings > Settings tab | Change the Framing from IBBP to IP |
| In the Advanced tab | Change the Codec Present to Baseline |
| Set GOP | Fixed Mode with 2000ms |
| Set Entropy coding mode | CABAC |
| Set Recommended Bitrate | 6,000 @ 1080p or 4,500 @ 720p |
*Note: The timestamp seeding seemed to be the magic change on the KBs.
Remember to set the frame rate to the same value as in your THEOlive channel ingest configuration and make sure that your encoder has a stable connection and enough upload bandwidth. See Stream configuration for more details.
