Abstract

Described are examples for obtaining data from a single stream output. An indication of requested data from multiple stream sources can be received from an application. A single stream output including one or more output frames can be received from a stream server where at least one output frame includes at least data from each of the multiple stream sources. The requested data can be extracted from the single stream output and provided to the application.

Claims

1. A method for obtaining data from a single stream output, comprising:

receiving, from an application, an indication of requested data from multiple stream sources;

receiving, from a stream server, the single stream output including one or more output frames where at least one output frame includes data from each of the multiple stream sources;

extracting the requested data from one or more containers of the one or more output frames of the single stream output;

building a data structure comprising the requested data for providing to the application; and

providing the data structure to the application.

2. The method of claim 1, further comprising providing an interface to facilitate indicating the requested data, wherein the indication of the requested data is received from the application via the interface.

3. The method of claim 2, further comprising:

querying the stream server to determine a set of data available from the multiple stream sources; and

indicating at least a portion of the set of data for requesting via the interface.

4. The method of claim 1, further comprising:

determining whether the requested data from the multiple stream sources is available from the stream server; and

requesting, from the stream server, correlation of one or more of the multiple stream sources into the single stream output where it is determined that the requested data is not available from the stream server.

5. The method of claim 1, wherein providing the data structure to the application corresponds to a cadence at which the single stream output is received from the stream server.

6. The method of claim 1, wherein providing the data structure to the application comprises at least one of responding to the indication of requested data with the data structure or calling a callback function with the data structure.

7. The method of claim 1, wherein the data structure includes data of different media types.

8. A device for obtaining data from a single stream output, comprising:

a memory storing one or more parameters or instructions for executing a stream server, wherein the stream server interfaces with a plurality of stream sources; and

at least one processor coupled to the memory, wherein the at least one processor is configured to;

receive, from an application, an indication of requested data from multiple stream sources;

receive, from the stream server, the single stream output including one or more output frames where at least one output frame includes at least data from each of the multiple stream sources;

extract the requested data from one or more containers of the one or more output frames of the single stream output; and

build a data structure comprising the requested data for providing to the application; and

provide the data structure to the application.

9. The device of claim 8, wherein the at least one processor is further configured to provide an interface to facilitate indicating the requested data, wherein the indication of the requested data is received from the application via the interface.

10. The device of claim 9, wherein the at least one processor is further configured to:

query the stream server to determine a set of data available from the multiple stream sources; and

indicate at least a portion of the set of data for requesting via the interface.

11. The device of claim 8, wherein the at least one processor is further configured to:

determine whether the requested data from the multiple stream sources is available from the stream server; and

request, from the stream server, correlation of one or more of the multiple stream sources into the single stream output where it is determined that the requested data is not available from the stream server.

12. The device of claim 8, wherein the at least one processor is configured to provide the data structure to the application corresponding to a cadence at which the single stream output is received from the stream server.

13. The device of claim 8, wherein the at least one processor is configured to provide the data structure to the application at least in part by at least one of responding to the indication of requested data with the data structure or calling a callback function with the data structure.

14. The device of claim 8, wherein the data structure includes data of different media types.

15. A computer-readable medium, comprising code executable by one or more processors for obtaining data from a single stream output, the code comprising code for:

receiving, from an application, an indication of requested data from multiple stream sources;

receiving, from a stream server, the single stream output including one or more output frames where at least one output frame includes at least data from each of the multiple stream sources;

extracting the requested data from one or more containers of the one or more output frames of the single stream output;

building a data structure comprising the requested data for providing to the application; and

providing the data structure to the application.

16. The computer-readable medium of claim 15, wherein the code further comprises code for providing an interface to facilitate indicating the requested data, wherein the indication of the requested data is received from the application via the interface.

17. The computer-readable medium of claim 15, wherein the code further comprises code for:

determining whether the requested data from the multiple stream sources is available from the stream server; and

requesting, from the stream server, correlation of one or more of the multiple stream sources into the single stream output where it is determined that the requested data is not available from the stream server.

18. The computer-readable medium of claim 15, wherein the code for providing provides the data structure to the application corresponds to a cadence at which the single stream output is received from the stream server.

19. The computer-readable medium of claim 15, wherein the code for providing provides the data structure to the application at least in part by at least one of responding to the indication of requested data with the data structure or calling a callback function with the data structure.

20. The computer-readable medium of claim 15, wherein the data structure includes data of different media types.
