+LOW LATENCY PLAYBACK
+mpv is optimized for normal video playback, meaning it actually tries to buffer
+as much data as it seems to make sense. This will increase latency. Reducing
+latency is possible only by specifically disabling features which increase
+The builtin ``low-latency`` profile tries to apply some of the options which can
+reduce latency. You can use ``--profile=low-latency`` to apply all of them. You
+can list the contents with ``--show-profile=low-latency`` (some of the options
+are quite obscure, and may change every mpv release).
+Be aware that some of the options can reduce playback quality.
+Most latency is actually caused by inconvenient timing behavior. You can disable
+this with ``--untimed``, but it will likely break, unless the stream has no
+audio, and the input feeds data to the player at a constant rate.
+Another common problem is with MJPEG streams. These do not signal the correct
+framerate. Using ``--untimed`` or ``--no-correct-pts --fps=60`` might help.
+For livestreams, data can build up due to pausing the stream, due to slightly
+lower playback rate, or "buffering" pauses. If the demuxer cache is enabled,
+these can be skipped manually. The experimental ``drop-buffers`` command can
+be used to discard any buffered data, though it's very disruptive.
+In some cases, manually tuning TCP buffer sizes and such can help to reduce
+Additional options that can be tried:
+- ``--opengl-glfinish=yes``, can reduce buffering in the graphics driver
+- ``--opengl-swapinterval=0``, same
+- ``--vo=xv``, same
+- without audio ``--framedrop=no --speed=1.01`` may help for live sources
+ (results can be mixed)
