New Revision: 359406
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=359406
Log:
Add tests for main/jitterbuf.c
This patch adds unit tests for main/jitterbuf.c. This includes checking for
the following:
* Nominal insertion and retrieval of frames
* Insertion and retrieval of frames where the frames are inserted out of
order with respect to the previous frame
* Insertion and retrieval of frames where some number of frames that would
occur in the expected sequence are instead dropped
* Insertion and retrieval of frames with an arrival time that does not occur
at the same rate as the surrounding frames
* Resynchronization of the jitter buffer when an inserted frame breaks the
resynchronization threshold
* Overfilling of the jitter buffer
For each of the tests, both JB_TYPE_VOICE and JB_TYPE_CONTROL permutations
exist.
