Green screen error in VLC

[Paul Smith]

Dear All,

This happens after upgrading from F25 to F26, when playing a video --
no image; only a green screen. Any ideas?

Thanks in advance,

Paul

Which GPU do you have and what is your setting in vlc's 
"Tools->Preferences->Video->Output"?

Since having upgraded to F26[1], I facing similar issues as you describe 
them on 2 Haswell's IGPUs.

Playing with "Output", I found the only working one seems to be
"XVideo output (XCB)" while all the rest - comprising "Automatic" - seem 
dysfunctional.

[1] I did not have these issue on the same machines with FC25. One of 
these machine is in a dual boot config with F25, so I can try FC25 (when 
time permits).

Thanks, Ralf. By setting "Output" to "XVideo output (XCB)", instead of
"Automatic", did the trick. But should this be considered a bug?

Since vlc is packaged by RPMfusion and vlc has its own website and support page I
would go http://www.videolan.org/support/ and ask them as they will probably have a
more definitive answer.  They even have their own mechanism for reporting bugs which,
if it is a bug, would get faster results than putting a bugzilla in at RPMfusion and
then just have them have to push it upstream.

IMO, yes, definitely.

The problem however is, it's hard to tell which component (package) is 
the actual cause. vlc is involved but from what I see from the error 
messages vlc emits, there are more bugs involved underneath.
