For Rpi4 platform - Run the below command in all terminals where you need to run the rialto commands.
| export WESTEROS_DRM_CARD=/dev/dri/card0 |
|---|
Note: In case of Rpi3 platform, no need to run the above command. Since, Rpi3 uses only one master card.

Start server manager simulator:

Note:
If you are not able to play HLS using rialto-mse sinks, then try to increase value of RIALTO_SESSION_SERVER_STARTUP_TIMEOUT_MS (>2000) or remove the TIMEOUT. So, there will be no startup limit.Run Rialto Server for YouTube:

There is a small correction in the below "Run YouTube" Command mentioned in rdk wiki page
remove "$PWD" in COBALT_CONTENT_DIR
This approach had flaws as considering the fact that RialtoServer shouldn't be started by service file directly.
libRialtoServerManager.so should be responsible for creating an insatnce of RialtoServer which should spawn the socket for running rialto.
As mentioned above the latest approach was to integrate libRialtoServerManager.so to RDKShell which would give RDKShell the access to invoke API's.
API's to be invoked via RDKShell.
initiateApplication - causes for a new RialtoSessionServer instance to be spawned.
https://github.com/vijith-tv/rdkservices/blob/sprint/23Q2/RDKShell/RDKShell.cpp#L3517 places for invoking the API suggetsed by Michael
changeSessionServerState - requests an session server to change its state
https://github.com/vijith-tv/rdkservices/blob/sprint/23Q2/RDKShell/RDKShell.cpp#L4011 - suspend
https://github.com/vijith-tv/rdkservices/blob/sprint/23Q2/RDKShell/RDKShell.cpp#L4086 - destroy
