The bridging API<br>has also been extended slightly to allow setting this so bridge_softmix<br>can use it.<br><br>ASTERISK-27786<br><br>Change-Id: I0e49eae60f369c86434414f3cb8278709c793c82<br>---<br>M apps/app_confbridge.c<br>M apps/confbridge/conf_config_parser.c<br>M apps/confbridge/include/confbridge.h<br>M configs/samples/confbridge.conf.sample<br>M include/asterisk/bridge.h<br>M main/bridge.c<br>6 files changed, 36 insertions(+), 0 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.asterisk.org:29418/asterisk refs/changes/16/8716/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">diff --git a/apps/app_confbridge.c b/apps/app_confbridge.c<br>index 2527863..5907bf9 100644<br>--- a/apps/app_confbridge.c<br>+++ b/apps/app_confbridge.c<br>@@ -1543,6 +1543,7 @@<br> } else if (ast_test_flag(&conference->b_profile, BRIDGE_OPT_VIDEO_SRC_SFU)) {<br> ast_bridge_set_sfu_video_mode(conference->bridge);<br> ast_bridge_set_video_update_discard(conference->bridge, conference->b_profile.video_update_discard);<br>+ ast_bridge_set_remb_send_interval(conference->bridge, conference->b_profile.remb_send_interval);<br> }<br> <br> /* Link it into the conference bridges container */<br>diff --git a/apps/confbridge/conf_config_parser.c b/apps/confbridge/conf_config_parser.c<br>index 71da802..f9d7483 100644<br>--- a/apps/confbridge/conf_config_parser.c<br>+++ b/apps/confbridge/conf_config_parser.c<br>@@ -458,6 +458,18 @@<br> video update requests from clients.<br> </para></description><br> </configOption><br>+ <configOption name="remb_send_interval" default="0"><br>+ <synopsis>Sets the interval in milliseconds that a combined REMB frame will be sent to video sources</synopsis><br>+ <description><para><br>+ Sets the interval in milliseconds that a combined REMB frame will be sent<br>+ to video sources.
