MediaManager serves as entry point for running media performance tests.
|
||||
It is responsible for the following
|
||||
1. Manage life-cycle of the mozHttpdServer and browser instance
|
||||
2. Provide RESTP API handlers for the Media tests
|
||||
3. REST API design follows the pattern
|
||||
<resource>/<component>/<operation>
|
||||
Example: audio recorder functionality
|
||||
==> audio/recorder/start, audio/recorder/stop
|
||||
For audio pesq functionality
|
||||
==> audio/pesq/compute
|
||||
For Stopping the server and browser
|
||||
==> server/config/stop
|
||||
|
||||
The idea here is to allow easy specification of resources
|
||||
(audio, video, server) , components (tools such as PESQ, SOX)
|
||||
and the operations on them (start, stop, computue..)
|
||||
|
||||
NOTE: Using PESQ seems to have licensing issues. Hence for time being
|
||||
usage of PESQ is replaced by the SNR computation.
