Mobile streaming to DaCast and Akamai

Larix mobile SDK allows publishing live streams from mobile devices to wide variety of destinations like media servers and streaming services. Some destinations require special handling due to authorization or other concerns.

DaCast service provides a turn-key solution for live streaming. It uses Akamai CDN for ingest and delivery, making it simple for an average user to get it working. However, Akamai has its requirements for authorization and other stream parameters. Nimble Streamer allows publishing to Akamai already so we've added the same support into Larix Broadcaster.

Here is how you can get it working.

Set up DaCast stream


We assume you already have DaCast account, so just open the dashboard and add a new stream.



Click on the stream name to see its full setup details. Click on Encoder tab on top to see the encoder setup details.

Click on Other RTMP encoder to see full parameters of RTMP connection.



Here you see Login and Password values which you will use later in Larix.

Now click on "Click if your encoder has one field" link to see a field with full URL for publishing.


Copy this full URL for later use, it should look like this:
rtmp://p.ep123456.i.akamaientrypoint.net/EntryPoint/dclive_1_150@123456

While you're in DaCast dashboard, check Publish settings tab to get a player page in order to check future result of your setup.

Now let's get to Larix setup.

Set up Larix Broadcaster


Larix Broadcaster is available for both Android and iOS platforms so just install it as usual.

Open the app and and enter settings by tapping on gear icon.

Tap on Connections -> New connection to enter a form below.



  • Name field can contain any alias you want for your connection. Larix Broadcaster allows streaming to multiple destinations simultaneously, so this is how you will distinct them from one another.
  • URL field defines the target destination. Insert the URL which you copied in the previous section.
  • Target type must be set to Akamai/DaCast.
  • Login and Password need ot be exactly like you've seen in DaCast connection settings.

Save connection, get back to connections list and make sure you select this new connection.
Now return to image preview screen and just hit the red button to start streaming.

Now check DaCast player page from previous section to watch the results.

Akamai


This setup procedure is applied the same way for publishing to Akamai CDN via RTMP. The publishing URL will have the same structure with same type of credentials. Larix Broadcaster target type is also "Akamai/DaCast". Please refer to Akamai website to learn more about its setup.



If you have any issues with this feature set, just let us know.
