UxPlay). <strong>New: the UxPlay build script will now also detect
Homebrew installations in non-standard locations indicated by the
environment variable <code>$HOMEBREW_PREFIX</code>.</strong></p>
<p><strong>Using GStreamer installed from MacPorts</strong>: this is
<strong>not</strong> recommended, as currently the MacPorts GStreamer is
old (v1.16.2), unmaintained, and built to use X11:</p>
<p><strong>Using GStreamer installed from MacPorts</strong> : (MacPorts
is now again supplying current or recent Gstreamer). Before building
UxPlay, install the MacPorts GStreamer with
“<code>sudo port install gstreamer1 gstreamer1-gst-plugins-base</code>”.
Plugins are installed by
“<code>sudo port install gstreamer1-gst-plugins-*</code>” where
“<code>*</code>” is “good”, “bad”, (and optionally “ugly”). For the
libav plugin,
“<code>sudo port install ffmpeg6 [+nonfree] gstreamer1-gst-libav</code>”
(where “+nonfree” is optional, and makes linked GPL binaries
non-distributable). Unfortunately, the current MacPorts GStreamer build
(bug or feature?) does not provide the opengl plugin, so the only
working videosink it provides is osxvideosink. (Hopefully this will be
corrected). <em>It is also possible to install an X11-based GStreamer
with MacPorts, (add ” +x11” after “base”, “good” “bad” and “ugly” in the
plugin names): for X11 support on macOS, compile UxPlay using a special
cmake option <code>-DUSE_X11=ON</code>, and run it from an XQuartz
terminal with -vs ximagesink; older non-retina macs require a lower
resolution when using X11: <code>uxplay -s 800x600</code>.</em></p>

<p>After installing GStreamer, build and install uxplay: open a terminal

downloads, “UxPlay” for “git clone” downloads) and build/install with
