To install gstreamer1. Try making the audio queue larger, or set tune=zerolatency on x264enc. For gstreamer rtspsrc this is the 'latency' parameter - we set it to 10ms to minimize latency as a value of 0 can confuse gstreamer. GstBaseSink handles many details for you, for example: preroll, clock synchronization, state changes, activation in push or pull mode, and queries. The jitterbuffer also eliminates network jitter and then tracks the drift between the local clock (as expressed in the GStreamer timestamps) and the remote clock (as expressed in the RTP timestamps). It provides the scaffolding for connecting media elements called plugins. Unlike most GStreamer elements, Appsrc provides external API functions.
