** Description changed:
[Impact]
gstreamer cannot load some plugins on 20.04, aarch64 due to TLS memory
exhaustion, so these plugins cannot be used. See LP: #1846837 and LP:
#1914030.
This is solved apparently on glibc 2.32:
https://sourceware.org/bugzilla/show_bug.cgi?id=25051
by patch
https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=ffb17e7ba3a5ba9632cee97330b325072fbe41dd
[Test Case]
Running totem-video-thumbnailer shows TLS error in the version not
fixed, generates thumbnail with the fixed version:
$ sudo apt -y install totem gstreamer1.0-libav
...
$ wget
https://ia800201.us.archive.org/12/items/BigBuckBunny_328/BigBuckBunny_512kb.mp4
...
$ totem-video-thumbnailer BigBuckBunny_512kb.mp4 thumbnail.png
...
(totem-video-thumbnailer:3602): GStreamer-WARNING **: 18:36:10.466: 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 block
...
[Where problems could occur]
This is delicate code in glibc with quite regression potential. Said
this, the code is in the next major release (2.32, while focal has
2.31), which has been running groovy for a while.
Also, apparently there is a 2.31 patch for groovy, before it moved to
2.32: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964141
+
+ Regressions in 2.31-0ubuntu9.3 have been observed in LP: #1926379 and
+ LP: #1926387.
** Changed in: glibc (Ubuntu Focal)
