gstreamer1.0-libav breaks video playback
gstreamer1.0-libav is supposed to make video playback faster and supporting more formats by using libav but that's broken on aarch64:
e.g. when playing videos in epiphany:
(WebKitWebProcess:1957): GStreamer-WARNING **: 10:37:41.690: Failed to load plugin '/usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstlibav.so': /lib/aarch64-linux-gnu/libgomp.so.1: cannot allocate memory in static TLS blockthis can be worked around by:
LD_PRELOAD=/lib/aarch64-linux-gnu/libgomp.so.1 epiphanywhich gives okish video speed.
