I wish I could say it was still working. But either it stopped working, or I confused "X11 video output (XCB)" for "XVideo output (XCB)" because it was late. XVideo output (XCB), or xcb_xv, is not working for me for most h264 videos, and the things I speculated about in my last comment did not affect this (including re-enabling logging and restarting rsyslogd).
It's not directly related to video quality or the h264 'level' or profile. I can play a 3840x2160 h264 dash video from Youtube with no audio, but a 1280x720 h264 dash video from the same source, with a creation date in its metadata of just 7 minutes before the other video, won't play and gives the same errors in debug as in the original report. VP9 and VP8 work fine, h265 seems to work fine, mpeg4 (divx tag) works fine, apparently mpeg2 doesn't work either. Some files with the 'wmv' suffix don't work, with the same error. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1440254 Title: Recent update broke XVideo/XCB output for h264 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vlc/+bug/1440254/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
