Backport of patch already present upstream to fix issues with invalid
characters for GLIB when combining gstreamer1.0-libav with ffmpeg 5.x.

Remove when gstreamer1.0-libav is upgraded to 1.21.1 or above

Thanks for the feedback.

Will send a version 2 shortly where I have updated the patch file with
this info.

+Subject: [PATCH] libav: Fix for APNG encoder property registration
+
+The AVClass name of Animated PNG in FFmpeg 5.x is "(A)PNG"
+and it will be converted to "-a-png" through
+g_ascii_strdown() and g_strcanon(). But GLib disallow leading '-'
+character for a GType name. Strip leading '-' to workaround it.
