gstreamer1.0-libav is broken on aarch64, at least on Ubuntu 20.04/20.10
Hello!
Attempt to playback a regular mp4 video file in Totem on Ubuntu 20.04/20.10 aarch64 ends with following error:
"(totem:16289): GStreamer-WARNING **: 10:16:03.188: Failed to load plugin '/usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstlibav.so': /lib/aarch64-linux-gnu/libgomp.so.1: can't allocate memory in static TLS block" (translated; original message was "невозможно выделить память в статичном блоке TLS").
Probably this issue caused totem-video-thumbnailer breakage too: https://bugs.launchpad.net/ubuntu/+source/gst-libav1.0/+bug/1846837
This issue is reproducible on Qualcomm Snapdragon 850 (Lenovo Yoga C630 WOS) and Rockchip RK3399 (Libre Computer Renegade Elite).
