ubuntu 16.04.1 / "xenial" vlc 2.2.2-5 VLC memory consumption grows continuously (32 GiB RAM in 10 minutes) while displaying MPEG-2 video (whether playing or paused) using VDPAU display plugin, at least with Intel Skylake GPU.
see Tools → Preferences → Video → Video Settings → Display → Output → VDPAU output. If set to "Automatic", which is the default, then only if the VDPAU display plugin is applicable and used (eg MPEG-2, but not MPEG-4; verify: Tools → Messages → Modules Tree tab → libvlc → playlist → video output → vout display "vdpau_display") does the memory grow. VDPAU output is the default vout display plugin because it has the highest score of all (ie 300). All other plugins either don't work (eg DirectFB while running X11) or don't result in constantly increasing memory consumption. VDPAU is a poor choice, at least on Skylake (or maybe for all Intel hardware, ie libvdpau_va_gl.so → libva.so → i965_drv_video.so), because it doesn't support video resizing (ie open MPEG-2 at 720x480 and upon full-screening VLC, the video is still 720x480; though that might be specific to VLC and addressed by http://git.videolan.org/?p=vlc/vlc-2.2.git;a=commit;h=0e205d42). The problem appears to be specific to VLC, and not the underlying libraries (unless use of the underlying libraries differs between applications), because "mplayer -vo vdpau ..." uses the same libraries (ie libvdpau_va_gl.so, libva.so, i965_drv_video.so), but doesn't cause the same run-away memory consumption as VLC. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573210 Title: Huge memory leak when playing video in Ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/vlc/+bug/1573210/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
