* Enable built-in echo canceler if available.Chia-chi Yeh2011-01-061-3/+7
| | | | | | | 1. Always initialize AudioRecord with VOICE_COMMUNICATION. 2. If echo canceler is available, disable our echo suppressor. Change-Id: Idf18d3833189a8478c1b252ebe6ce55e923280b3

|\ | | | | | | | | | | | | every second. * commit 'dc78e3fe7f2ffbc810cd54e86e3a83e279d74984': RTP: Send silence packets on idle streams for every second.
| * RTP: Send silence packets on idle streams for every second.Chia-chi Yeh2011-01-041-32/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | Originally a stream does not send packets when it is receive-only or there is nothing to mix. However, this causes some problems with certain firewalls and proxies. A firewall might remove a port mapping when there is no outgoing packet for a preiod of time, and a proxy might wait for incoming packets from both sides before start forwarding. To solve these problems, we send out a silence packet on the stream for every second. It should be good enough to keep the stream alive with relatively low resources.
