Most "<a class="reference external" href="https://mpv.io/manual/master/#list-of-input-commands">input commands</a>" are mapped to methods of the MPV class. Check out these methods and their docstrings in <a class="reference external" href="https://github.com/jaseg/python-mpv/blob/main/mpv.py">the source</a> for things you can do. Additional controls and status information are exposed through <a class="reference external" href="https://mpv.io/manual/master/#properties">MPV properties</a>. These can be accessed like <tt class="docutils literal">player.metadata</tt>, <tt class="docutils literal">player.fullscreen</tt> and <tt class="docutils literal">player.loop_playlist</tt>.</p> +<div class="section" id="threading"> +<h3>Threading</h3> +<p>The <tt class="docutils literal">mpv</tt> module starts one thread for event handling, since MPV sends events that must be processed quickly. The +event queue has a fixed maxmimum size and some operations can cause a large number of events to be sent.</p> +<p>If you want to handle threading yourself, you can pass <tt class="docutils literal">start_event_thread=False</tt> to the <tt class="docutils literal">MPV</tt> constructor and +manually call the <tt class="docutils literal">MPV</tt> object's <tt class="docutils literal">_loop</tt> function. If you have some strong need to not use threads and use some +external event loop (such as asyncio) instead you can do that, too with some work. The API of the backend C <tt class="docutils literal">libmpv</tt> +has a function for producing a sort of event file descriptor for a handle. You can use that to produce a file descriptor +that can be passed to an event loop to tell it to wake up the python-mpv event handler on every incoming event.</p> +<p>All API functions are thread-safe. If one is not, please file an issue on github.</p> +</div> +<div class="section" id="advanced-usage"> +<h3>Advanced Usage</h3> +<div class="section"
