+        [GStreamer][WPE] Use WPE_SHELL_MEDIA_DISK_CACHE_PATH env var to customize media disk cache path
+        https://bugs.webkit.org/show_bug.cgi?id=233477
+
+        Reviewed by Xabier Rodriguez-Calvar.
+
+        "/var/tmp" isn't always the best place to store the media download cache generated by GstDownloadBuffer
+        on embedded platforms. Each of those downloads can hold up to a whole movie (Gigabytes) and "/var/tmp"
+        is sometimes a memory based tmpfs. Some way to control the cache path is needed.
+
+        * platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.cpp: Honor environment variable.
