Changeset 1726 for pjproject/branches/users/nanang/pjmedia/src/pjmedia/transport_srtp.c

Timestamp:

Jan 22, 2008 10:31:13 PM (16 years ago)

Author:

Message:

Ticket #452:

• added part to test specific key, only for testing purpose
• replaced pool instance for parsing SDP and generating key (from suplied pool param of media_create/start to internal srtp pool)
• bug fixed in send rtcp callback
• changed mutex type from null mutex to recursive mutex
• changed srtp transport destroy: using mutex and reordering step.
