I experience a very simmilar problem here. For a few seconds, video is very well and the next few seconds I have those problems you describe. It seams that sound also has some problems while video stutters (at least here), but it is not this noticeable. The problem does not happen when using the normal monitor as output device. I'm noticing these effects on a less noticeable basis with Softdevice, and here I get the audio stutters. With softdevice cpu can max out on my P3 550Mhz, especially when the OSD is shown. Whats strange is top shows cpu cost shifting constantly from less than 20% to +97%. I've never seen this behaviour with softdevice before (first time using xine-lib). What sort of hardware do you have? > Using latest vdr-xineliboutput, DirectFB-1.0.0 & xine-lib-1.1.5 using > Gentoo ebuilds. Exactly the same here, but on Debian Etch with all components built from source. That's vdr-xineliboutput 1.0.0rc1, DirectFB 1.0.0 and xine-lib 1.1.5 on Debian Etches default kernel (2.6.18). > Otherwise xineliboutput is working fantastically! Well, I think it's a bit hard to say that xineliboutput works fantastically as I can't rate it with this problems. But what I can say for sure is that CPU load is a bit lower than with softdevice. But sound works for me with both :) There seem to be some problems with aspect ratio with xineliboutput, but as you say, that's another issue... Greetings, Markus Fantastic was an exaggeration certainly..Just trying to be optimistic! CPU load lower with xine-lib here as well. On a purely visual basis, when xine-lib isn't stuttering (field sync tripping out?) the image is actually better than my set top box. Colours arn't as harsh, video is less pixelated , text on my scrolling news channel is very good looking, almost anti-aliased :-) However the interlacing problems are happening every couple of seconds. In the original post I was just wondering if xineliboutput has been written with the matrox specific instructions that softdevice's "-vo dfb:mgatv" uses. As I don't understand the difference between "-vo dfb:" & "-vo dfb:mgatv" I can't really say what difference this would make. Should have mentioned I'm using a 16:9 CRT to view all this, and I don't have a monitor on the first head at all. Whats funny is that when I was last struggling with vdr-softdevice on an old 4:3 TV I could easily get fantastic output when I set the aspect to 16:9, of course this caused a huge overscan, meaning it wasn't much of an option. -- A l a s d a i r C a m p b e l l r a g a w u @ g m a i l . c o m ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Sorry for replying to myself, but in the meantime, while waiting for xineliboutput to work again, anyone reading know if I can use df_xine for the video display, while retaining xineliboutput as the lirc transport to my headless server running vdr-xineliboutput. ** I know there has been a tremendous amount of work from everyone in respect to Matrox TV-Out already, sorry to keep bugging you all ;-) ** -- A l a s d a i r C a m p b e l l r a g a w u @ g m a i l . c o m ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

There should be similar setting in $HOME/.xine/config_xineliboutput
(search for video.device.directfb_field_parity)
Maybe this is due to me running as root (I know this is bad, just for
testing) but each time I run vdr-fbfe it seems to clobber the
config_xineliboutput file, and reinstate "none" for field parity.
# field parity
# { none top bottom }, default: 0
#video.device.directfb_field_parity:none
Setting wait for vertical retrace stays set at 1, after setting it a
few minutes ago. I presume I want that with my G450.

If you have the softdevice source code laying arround, you can have a look in that, especially 'video-dfb.c'. Search for 'setupStore->useMGAtv'. There are some if-constructs in there using this variable where some DirectFB settings (and maybe some other settings, haven't looked this closely) are set.

[vdr] OSD layout
Has anyone done any work (or written a plugin) to update the standard OSD? I've not done this yet, but see you can change font size and colours using themes, but I was thinking more than this. I've now replaced my TV with a big high-res flat screen that could fit way more text etc on the screen.

That's funny, my config_xineliboutput doesn't have this config option per
default...
But I can insert it and when set to 'top' video quality is quite awesome, but
there are still some small hickups and stutters here and there (even with
vsync set to 1). Maybe some other settings are still missing, that softdevice
sets...
With Bloomberg (German news/stock channel) I see a very odd behavior: To have
to video itself fullscreen, I have to enable local frontend scaling but then
the OSD is renderd much too big. So I have to enable OSD resizing/downscaling
which results in a very unnice OSD (fonts look a bit ugly and the complete
OSD is not the nicest view.).
And channels broadcasting a 16:9 signal are always scaled up to my 4:3 CRT TV,
so I have the typical 'long faces' (I think that's only a configuration
setting, but I haven't been able to locate it...)
I'm currently not in a productive environment (that runs with a FF and VDR
1.26 :)) with software decoding, but from what I can say so long, using
DirectFB and the Matrox G450s TV-Out, softdevice is my personal favorite! I
think xineliboutput doesn't earn it's high version number in this 'special'
configuration.
BUT I have to admit that xineliboutput uses only half of the CPU power of
softdevice, so it's video decoder has to be more efficient...

Re: [vdr] OSD layout
Hi! Yes there are some VDR-Skin-Plugins around. For example mine at http://andreas.vdr-developer.org/enigmang What output device do you use? You should be aware that e.g. Full-Featured DVB-S cards have limited OSD capabilities (~90kb). So hires hi-color OSD will be a problem here.
