I only ask because I've only ever seen that error in the ppc64 environment, and not in the powerpc realm. In any case, we can make sure with uname -srp.
I used this image:
debian-10.0-powerpc-NETINST-1.iso
But chose the install-powerpc64 option on boot.
Here is the output of uname -srp:
Linux 4.19.0-5-powerpc64 unknown
Launch VLC from console again, then run cat /var/log/syslog and see what it says at the bottom portion, at the end area. Usually, something should stick out.
I ran tail -f /var/log/syslog in one console tab and then launched VLC in another. There was no output to syslog when VLC crashed. The last few lines are unrelated to VLC.
