VLC tearing during playback (only VLC, not mplayer/xine)

[colbert]

Specs: Q6600, Nvidia 8800GT, dual monitors Acer AL2616W @ 1920x1200 + NEC FE1250 @ 1600x1200. Using 180.22 stable drivers.

All has worked quite well for the longest time, but just today I noticed that video playback in VLC is tearing (horizontal lines and such during panning scenes in videos). I have tried numerous videos as well as various output modules. Here is output as an example:

Code: Select all

└─[/media/seagate/tv-newstuff/SD/Wolverine.and.the.X-Men]> vlc Wolverine.and.the.X-MenS01Ep13ns10.avi.avi VLC media player 0.9.8a Grishenko [00000001] main libvlc debug: VLC media player - version 0.9.8a Grishenko - (c) 1996-2008 the VideoLAN team [00000001] main libvlc debug: libvlc was configured with ./configure '--prefix=/usr' '--enable-dvdread' '--enable-dvdnav' '--enable-madi' '--enable-ffmpeg' '--disable-rpath' '--enable-qt4' '--enable-faad' '--enable-alsa' '--enable-skins2' '--enable-dvb' '--enable-dmo' '--with-ffmpeg-faac' '--with-ffmpeg-vorbis' '--with-ffmpeg-dts' '--with-ffmpeg-ogg' '--with-ffmpeg-theora' '--enable-v4l' '--enable-theora' '--enable-flac' '--enable-snapshot' '--enable-hal' '--enable-dbus' '--enable-ogg' '--enable-dbus-control' '--enable-shared' '--enable-nls' '--enable-lirc' '--enable-shout' '--enable-pvr' '--enable-release' '--program-suffix=' '--with-dv-raw1394=/usr/include/libraw1394' '--enable-loader' '--enable-live555' '--with-live555-tree=/usr/lib/live-media' 'CFLAGS=-march=i686 -mtune=generic -O2 -pipe' 'CXXFLAGS=-march=i686 -mtune=generic -O2 -pipe' 'PKG_CONFIG_PATH=/usr/lib/pkgconfig' [00000001] main libvlc debug: translation test: code is "C" [00000391] main interface error: no interface module matched ",none" [00000391] main interface error: no suitable interface module [00000001] main libvlc error: interface ",none" initialization failed [00000001] main libvlc: Running vlc with the default interface.

[????????] x11 video output error: X11 request 42.0 failed with error code 8: BadMatch (invalid parameter attributes) └─[/media/seagate/tv-newstuff/SD/Wolverine.and.the.X-Men]>

(I don't know that the "X11 request 42.0 failed with error code 8" is important as I've seen it before when all was fine.)

I have tested all the same video files with mplayer/xine and there is no tearing. I am using nvidia-settings Sync to VBlank settings and have keybindings to switch sync between screens. I suspect this may be caused by an update but don't know where to look or discover the source. I hope this can be fixed as VLC is far and away my fav player of all

Thanks

Did you try to deinterlace?

[colbert]

Yes I tried various deinterlacing modes, there is still some horizontal lines

xdpyinfo?
xvinfo?
64-bits system?
Did you try with '-V x11', '-V xv' and/or '-V opengl' ?

x11, xv and opengl don't solve it.

What is xpdyinfo/xvinfo? Don't know the command to do this?

I use 32-bit

Thanks

[colbert]

Anyone? Still can't fix this.

[Rémi Denis-Courmont]

Without your display infos, neither the VLC debug, it is safe to asssyme we cannot help you.

[colbert]

Okay, which display info do you need? My first post at the top I shared my specs. How can I provide the VLC debug? I will surely provide all this if you can tell me how, thanks

Are you building the latest (or close to the latest) version from source? If this is the case...

I posted a new topic regarding the use of XSync in xcommon.c - since this is related, do you think you can you try the following code change?

in the source file
modules/video_output/x11/xcommon.c

in the function
static void DisplayVideo( vout_thread_t *p_vout, picture_t *p_pic )

just before the end, there is a call to 'XSync()'. if you can add these two lines of code

XFlush( p_vout->p_sys->p_display ); // force commands to be sent
usleep(500); // then switch contexts before waiting

right before the end, like this:

static void DisplayVideo( vout_thread_t *p_vout, picture_t *p_pic )
...
// new lines start here
XFlush( p_vout->p_sys->p_display ); // force commands to be sent
usleep(500); // then switch contexts before waiting
// new lines end here
/* Make sure the command is sent now - do NOT use XFlush !*/
XSync( p_vout->p_sys->p_display, False );

vlc_mutex_unlock( &p_vout->p_sys->lock );
}

this might alleviate at least SOME of the problem you're seeing. if it does, then please comment in this thread (thanks). I'd like to see this patch or a similar one show up in the official vlc source.

FYI - I'm running FreeBSD 7.1 with ATI 'radeonhd' (development) driver that (unfortunately) doesn't support XVideo for my chipset, on a dual-core AMD64 (2.4Ghz) in 64-bit mode. This patch dramatically improves the rendering of videos that otherwise show a lot of "tearing" and "shearing". I use the 'SDL' output module which seems to work best when XVideo isn't available.

ugh i wish they could come up with a permanent fix, the lines bug me so much hah
