segmentation fault

[pinnerite]

Within the last week, all of my video programs (mythtv, kaffeine, vlc) ceased to work.

The last two report a segmentation fault.

memtest86 was run from liveDVD but reported no memory faults.

running all three from a terminal returned various messages:

Too bad you are not running Mageia 8 distribution. I see none of those
problems.

You should specify which distribution you're using and limit the newsgroup to
the one for that distribution.

In Mageia 8, r600_drv_video.so is /usr/lib64/dri/r600_drv_video.so from the
package lib64dri-drivers-21.3.9-1.mga8

Could be video driver. But a different version was used here.

https://www.reddit.com/r/voidlinux/comments/u39p59/kodi_crash_segmentation_fault_core_dumped/

https://bbs.archlinux.org/viewtopic.php?id=275053

"I have now tried after turning OFF hardware acceleration, and the DVD plays"

https://old.calculate-linux.org/issues/1092

"ERROR: Caught a segmentation fault while loading plugin file:
/usr/lib64/gstreamer-1.0/libgstvaapi.so"

So it could be the R600 driver, it could be something vaapi related.
Since the problem "survives" the usage of a different R600 driver
version, maybe the problem isn't exactly the R600 report.
The root cause could be the "caller" to the R600. As something VAAPI
is in the process of loading.

*******

If attempting to buy another brand of video card, check
carefully that it has the hardware accelerated decode and encode
you expect to be there. At least one cheap card for sale, is
missing a logic block for that.

*******

https://www.mythtv.org/wiki/VAAPI

Check to see if newly installed software is working by running

vainfo

Which should also potentially crash right now,
as soon as "vainfo" tries to reach that decoder stack.

Have you had a update for libc over the last week or two ?

There was one for MGA v8.

If you you will need to reload the system (reboot).

Do you get the same results with your junk user?

I later discovered that my /home partition had become full.
That may have been the reason for the "segmentation fault".

Sorry to have bothered you.
