vlc_debug_opengl_enabled_xcb_enabled.log

Confirmed bug.

Log from playing video with both opengl & xcb enabled.  Video plays fine.

Tested with mp4 sample from: http://techslides.com/sample-webm-ogg-and-mp4-video-files-for-html5

vlc_debug_opengl_enabled_xcb_disabled.log

VLC debug log from attempting to play same sample video as previous comment with opengl enabled and xcb disabled.

Both were tested under 2.2.1.  

So far I can't find a relevant bug upstream and will report this behavior

From reading the bug report @ URL:, I would be prompting them to reopen the bug, however it's a tough lesson about getting the correct info set outlined in the first place.  It's 50 50 % chance whether upstream devs will even re-visit the bug. Generally they do, in my exp., even if only to re-assert their initial opinion.
Comment 5 Nick Andrade 2015-04-19 03:18:03 UTC
Yeah, definitely.  At the very least this has taught me to pay more attention to the QA notice which clearly calls out that --enable-glx isn't used by configure.  I will try posting in their forums as well to try and get more info.

I was intending on doing it later, but fine.  The commit is 'correct'. New proxy maintainer (and I) hadn't quite got that far yet.
