 === Testing latency ===
 
-By default, ffplay (as a receiver for testing latency) introduces significant latency of its own, so if you use it for testing (see troubleshooting section) it may not reflect latency accurately. FFplay introduces some video artifacts, also, see notes for it in "troubleshooting streaming" section  Also some settings mentioned above like "probesize" might help it start more quickly.

Also useful:
+{{{
+ffplay -probesize 32 -sync ext INPUT
+}}}
+(the sync part tells it to try and stay realtime).
 
 Useful is mplayer with its -benchmark for testing latency (-noaudio and/or -nocache *might* be useful, though I haven't found -nocache to provide any latency benefit it might work for you).
