Media Handler and Storage
The media Handler manages your captured audio storage, it recieves audio from the Audio Connector and processes it according to Storage and Export Policies, when requested by the application the Media Handler will retrieve and provide the captured audio to the application for playback.
The Media Handler receives audio from the Audio Connector in PCM 16 stereo format, this way the call audio can be stored and processed in a consistent way. The call audio will have a Conversation ID associated with it, which is used to identify the call throughout the system, and allows the system to query specific calls and tie conversations together.
Using MinIO the Media Handler sends the audio over GRPC to the configured S3 storage, ready to be retrieved when needed. When a user opens a live or captured call in the UI, a request will be sent to the Media Handler with the Conversation ID to retrieve the call and stream it to the application via GRPC.
For more information on configuring storage in a U-Capture system see Manage Endpoints and Storage Locations.
For information on S3 storage by Amazon, see Amazon's documentation here.
Note
The above summarizes how call audio is processed and stored by the media handler for U-Capture, the Media Handler is an X-Platform component and can be used other applications, see the relevant documentation for details.
