Kurento:
- Backport memory leak fixes for lossy environments from upstream gstreamer
- Backport Kurento/kms-elements#27: this adds two new options (
externalIPv4/externalIPv6) which supersede the currentexternalAddressconfig to make it dual stack (IPv4+IPv6) friendly. - Backport Kurento/kms-elements#26: add a new configuration option (
niceAgentIceTcp) to allow disabling TCP ICE candidate gathering. TCP is usually closed on firewalls on regular deployments, so by deactivating them we halve the number of server-side * Kurento candidates while also speeding up connectivity. - Adjustments to Kurento's audio jitterbuffer: improves listen only audio quality.
