 == Latency ==
 You can decrease latency by specify that I-frames come "more frequently" (or always, in the case of x264's zerolatency), though this can increase frame size/decrease quality, see [http://mewiki.project357.com/wiki/X264_Encoding_Suggestions here] for alternatives.

+== Streaming a simple RTP audio stream from ffmpeg ==
+
+FFmpeg can stream a single stream using the RTP protocol. In order to avoid buffering problems on the other hand, the streaming should be done through the -re option, which means that the stream will be streamed in real-time.
+
+For example the following command will generate a signal, and will stream it to the port 1234 on localhost:
+{{{
+ffmpeg -re -f lavfi -i aevalsrc="sin(400*2*PI*t)" -ar 8000 -f mulaw -f rtp rtp://127.0.0.1:1234
+}}}
+
+To play the stream with ffplay, run the command:
+{{{
+ffplay rtp://127.0.0.1:1234
+}}}
