and I get this message:
| Code: |
This is xawtv-3.95, running on Linux/i686 (2.6.15.1)
WARNING: v4l-conf is compiled without DGA support.

What's wrong and how to fix it? |

Try right clicking the window to get options, then switching from overlay to grabdisplay mode?
Post an `emerge --info` too.
You could also try starting xawtv with the -noxv switch.
It's not a bad idea to upgrade to something like kdetv/tvtime/mythtv/vlc/tc either. |

grabdisplay works but is not watchable. It's like dropping 60% of the frames.
Everything worked fine before.

I could perhaps add that I can't get any sound when trying to record with mplayer
mencoder tv://E5 -tv device=/dev/v4l/video0:driver=v4l2:width=640:height=480:alsa -o /home/oldefortran/TV.avi -ofps 25 -ovc lavc -oac lavc -lavcopts vcodec=mpeg4:acodec=mp3:vhq:vbitrate=1800 -vf lavcdeint -of avi
The only difference between earlier and now is a kernel upgrade and a lot of package upgrades, mplayer has not been recompiled yet. |

Hi,
you are using nvidia, right?
you are using some of their latest drivers, correct?
change 'overlay' to 'grabdisplay' and you get your picture back - this is a well known bug in the nvidia drivers.
Oh, and xdtv works a little bit better than xawtv for me

| well, I get the picture but it's dropping 50% of the frames and it's not watchable. I had it working earlier without any problems on the same machine. Should I switch back to the 0.7xx nvidia driver (where it worked) instead of the new 0.8xx that I have just installed? |

Switching back to old nvidiakernel/glx didn't work.  |

But it worked with xawtv 0.94 instead of 0.95.
Great! |

I had this error too before (using the 'nv' drivers for X and vesatng for framebuffer).
These are the notes I made on solving it. The resolution is in manually telling xawtv what area to use for overlay using the command v4l-conf.
Below are the notes I jotted down while solving it.
on first run, I got the error:
WARNING: Your X-Server has no DGA support
WARNING: couldn't find framebuffer base address, try manual
configuration ("v4l-conf -a <addr>")
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to typ
e FontStruct
Xlib: extension "GLX" missing on display ":0.0".
ioctl: VIDIOC_OVERLAY(int=1): Invalid argument
=> I tried to add DGA support and the GLX extension
in /etc/X11/xorg.conf, do the following in the Module section:
Comment out the line
#Option "omit xfree86-dga"
Add the line
Load glx
A second start resulted in
WARNING: Your X-Server has no DGA support.
WARNING: couldn't find framebuffer base address, try manual
configuration ("v4l-conf -a <addr>")
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-
*" to type FontStruct
ioctl: VIDIOC_OVERLAY(int=1): Invalid argument
The command
>xawtv -hwscan
resulted in
This is xawtv-3.94, running on Linux/i686 (2.6.12-suspend2-r6-vesatngfb)
looking for available devices
port 61-92
type : Xvideo, image scaler
name : NV Video Blitter
/dev/video0: OK [ -device /dev/video0 ]
type : v4l2
name : BT878 video (Pinnacle PCTV Stud
flags: overlay capture tuner
Next trying to configure the framebuffer manually as sugested in the first output
detect the address of the framebuffer first, then use that to configure v4l
>dmesg | grep framebuffer
vesafb: framebuffer at 0xe4000000, mapped to 0xc8880000, using 2560k, total 16384k
>v4l-conf -a 0xe4000000
v4l-conf: using X11 display :0.0
WARNING: Your X-Server has no DGA support.
using user provided base address 0xe4000000
mode: 1280x1024, depth=24, bpp=32, bpl=5120, base=0xe4000000
/dev/video0 [v4l2]: configuration done
next step: strying to get channels scanned
>scantv -n PAL -f europe-west -C /dev/vbi0 > .xawtv # apparently, udev assigns vbi0, scantv expects vbi as default
With this, xawtv could start up. However, it still shows a problem when displaying images: stripes at the left side of the screen. This time, I found a FAQ explaining it had to do with the inability of the PCI bus to handle the data rates. To counter this, I added AGP support
>echo agpgart >> /etc/modules.autoload.d/kernel2.6
I also changed the defaultdepth of the X server to 16 bpp (in /etc/X11/xorg.conf). A later attemp to return to 24 bit resulted in the problem returning, so now I stay at 16 bit.
TODO: no DGA support (getting DGA support could result in no more need for the manual configuration). It may not be supported by the nv driver. |

| Shouldn't DGA be avoided with the NVidia driver? |

Just a guess but in your | Quote: | | /etc/X11/xorg.conf |
in you comment out or have these lines?
| Quote: | # This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
SubSection "extmod"
# Option "omit xfree86-dga" # don't initialise the DGA extension
EndSubSection
|
Hope it helps

I will try that when I want new problems since I've got it to work and dont' feel like tampering with it right now.
But does it really has any difference if I write
| Code: |
# SubSection "extmod"
# Option "omit xfree86-dga"
# EndSubsection |
or | Code: |
SubSection "extmod"
# Option "omit xfree86-dga"
EndSubsection |
In the first case, will it use default values for the extmod section? |

| Oh, I should perhaps stop loading extmod and uncomment the lines you mention. |

I've been having trouble with xawtv lately. The problems ocurred when I upgraded to xorg-x11-7.0-r1 and to xawtv-3.95-r1. I'm sure these are the causes of the problems, but I haven't seen many posts explaining why. I'd like to stay with the latest xorg.
In order to get xawtv to work for me, I took a few suggestions from this post. I've commented out the 'extmod' line and set xawtv to 'grabdisplay'. This seems to get xawtv to work. However, it can't display in fullscreen mode very well, AND the picture is definitely not as clear as previously.
Is xawtv just not going to work with xorg-x11-7* until a new release? Or is there a way to get xawtv's 'overlay' setting to work? |
