After upgrading to Ubuntu 20.10, VLC started crashing when I tried to
play video. I tried changing to different video output methods, but none
of them worked. In the past, I remember several methods working fine.
In the ffmpeg advanced preferences page, disabling the direct rendering
option made video playback work.
I thought the vaapi errors VLC reports had something to do with it, but
apparently not, because they still happen with successful playback. This
is on a Dell Inspiron 6400 with ATI Mobility Radeon X1400, which doesn't
support hardware decoding of the H.264 video I'm trying to play.
Here's one backtrace:
Thread 26 "vlc" received signal SIGSEGV, Segmentation fault.
