Time.png Outdated: The information on this page may no longer be relevant to the current release of MythTV, 31.0. Please consider helping to update it.

Important.png Note: PVR-350 Tv-out support has been dropped from MythTV 0.23 since it was unmaintainable and little used.

This How-To outlines how to get the X Driver (with xv extensions) working on the TV-Out of the Hauppauge PVR-350 in various distributions of Linux.

Configuring X (xorg.conf) (all distributions)

This section describes the changes you will need to make to your XF86Config / xorg.conf file in order to enable the X driver.

  • Edit your xorg.conf (or XF86Config) file to contain the following. Replace with your own fbdev and BusID as appropriate (see below):
Section "Device"
        Identifier "Hauppauge PVR 350 iTVC15 Framebuffer"
        Driver "ivtvdev"
        Option  "ivtv" "/dev/fb2"
        Option "VideoOverlay" "on"
        Option "XVideo" "1"
        BusID  "PCI:0:10:0"
        Screen 0

Key points of this section:

  • Driver "ivtvdev" - This is the X driver you downloaded or compiled, I used the downloaded version compiled for XFree86 on my X.org dist:
  • Option "ivtv" "/dev/fb2" - Use ivtv and NOT fbdev. The fbdev is a built in module that is not compatible with ivtv 4.x, and generates all sorts of errors.
    • At least for current SVN snapshots of ivtv xdriver together with an up-to-date X.org (>=7.1), this seems to be wrong - you actually need Option "fbdev" "/dev/fb..." instead. --Gernot 08:59, 11 March 2007 (UTC)
  • Screen 0 - Each graphics device has a list of available screens for example an gforce fx5200 has screen 0 and screen 1:
  • Get your appropriate BusID (for your PVR-350, not your video card) by executing the following command:

X -scanpci (look for the line with iTVC15 MPEG-2 Encoder, and you may need to kill X first)

  • Get the appropriate fb device from /proc/fb:

cat /proc/fb

  • VideoOverlay and XVideo are for enabling XVideo extensions - the driver should work without them.
  • You will probably also want to add the Screen and Monitor sections:


Section "Screen"
        Identifier "TV"
        Device "Hauppauge PVR 350 iTVC15 Framebuffer"
        Monitor "NTSC Monitor"

  • You can now start X by typing X -screen TV

Compiling the X driver on a RedHat Compatible System

I also needed the x driver to get Xine to play nice with the PVR-350. These steps worked to compile it on a CentOS 4.2 (RedHat Enterprise) x86_64 System:

  • Download and extract xdriver source. Here I'll use the home directory (~).
  • Install xorg-x11 source RPM, for me xorg-x11-6.8.2-1.EL.13.20.src.rpm
  • cd /usr/src/redhat/SPECS/
  • rpmbuild -bc xorg-x11.spec -- This took a good half hour on my 2.8Ghz P4-521. This patches and compiles but does not install the source. I wonder if 'rpmbuild -bp' would be enough for this to work?
  • cd ~/ivtv_xdriver_0.10.6/xc/programs/Xserver/hw/xfree86/drivers/ivtv
  • xmkmf /usr/src/redhat/BUILD/xorg-x11-6.8.2/xc
  • make
  • cp ivtvdev_drv.o /usr/X11R6/lib64/modules/drivers. On an i386 system the destination for the copy should be /usr/X11R6/lib/modules/drivers.
  • Edit /etc/X11/xorg.conf (see above edits to XF86Config).
  • Restart X

The xdriver source compiled without any patches or fixes. Check /var/log/Xorg.0.log after restarting X to see that the driver is loading. My log file stated that the driver is compiled for while I clearly have 6.8.2 installed. Odd, but it still works.

Compiling the X driver on Gentoo with Modular X.org (7.0-r1)

  • xf86-video-ivtvdev is now in portage!
  1. Add the following to /etc/portage/package.keywords:
    echo "x11-drivers/xf86-video-ivtvdev ~* *" >> /etc/portage/package.keywords
  2. Add the fbcon use flag to /etc/portage/package.use:
    echo "media-tv/ivtv fbcon" >> /etc/portage/package.use
  3. Add the following lines to /etc/portage/package.mask to prevent x.org from updating:
  4. Edit the following line in /etc/make.conf to contain ivtvdev. An example line:
    VIDEO_CARDS="nv nvidia vga vesa fbdev ivtvdev none"
  5. emerge ivtv
  6. If you don't already have xorg 7.0-r1:
    emerge xorg-x11
  7. xf86-video-ivtvdev should install itself, but if it doesn't:
    emerge xf86-video-ivtvdev
  8. Edit your xorg.conf file as shown in the previous section.

Important.png Note: Depending on the kernel version you have installed, a patched version of xf86-video-ivtvdev may be needed. This should really be kernel-independent, but it's not, so we make it work. If you have a problem getting xf86-video-ivtvdev to compile, try the patches on bugs.gentoo.org or post your compile errors to the IVTV or myth mailinglist.

Compiling the X driver on Gentoo with Modular X.Org (6.9/7.0)

Since Modular Xorg has drivers in separate packages, porting the xdriver to one of these packages was just a matter of hijacking the fbdev package and changing which files it compiled.

  1. Put the tar.bz2 file in /usr/portage/distfiles
    cp xf86-video-ivtvdev-0.10.6.tar.bz2 /usr/portage/distfiles
  2. Put the .ebuild in your portage overlay under x11-drivers/xf86-video-ivtv
    mkdir -p /usr/local/portage/x11-drivers/xf86-video-ivtvdev/
    cp xf86-video-ivtvdev-0.10.6.ebuild /usr/local/portage/x11-drivers/xf86-video-ivtvdev/
  3. Build the digest for the ebuild
    ebuild xf86-video-ivtvdev-0.10.6.ebuild digest
  4. Add the package to package.keywords
    echo "x11-drivers/xf86-video-ivtvdev ~x86" >> /etc/portage/package.keywords
  5. Add "ivtvdev" to VIDEO_CARDS in make.conf
  6. Add video_cards_ivtvdev to USE in make.conf
  7. Emerge the package
    emerge xf86-video-ivtvdev
  8. Edit xorg.conf (see configuration instructions above)
  9. Start X!

Important.png Note: These are copies of the source code obtained from ivtvdriver.org, modified for the package structure of modular xorg.

  • ivtvdev_drv.so Binary Driver (no guarantees on if this will work with your specific distribution, you're better off compiling)

Compiling the X driver on Gentoo with X.Org 6.8.X

Important.png Note: These instructions are outdated and may no longer work.

This section focuses on installing the X Driver (with XVideo extensions) in Gentoo under x.org 6.8.X. This assumes that you have tvout working on the PVR-350, or at least some parts of MythTV already working.

  • Upgrade to the newest release of Ivtv, at this time, ivtv-0.3.8.
ACCEPT_KEYWORDS=~x86 emerge ivtv
  • Upgrade/Install x.org. I used version 6.8.2-r5, but any new-ish release should be ok
  • Download the XDriver from here: http://dl.ivtvdriver.org/xdriver/
  • Unzip the archive into the source directory for X, in the

xc/programs/Xserver/hw/xfree86/drivers/ivtv directory

  • Edit xc/config/cf/xorg.cf and look for #define XF86CardDrivers. Add "ivtv" somewhere in that list.
  • Run a make clean and make install in that directory to install the ivtv driver.
  • Edit your XF86Config or xorg.conf file as shown above
  • Start X!

In order to facilitate, I created a patch and custom ebuild to download/install xdriver and patch the xorg.cf file.

  • attachment:ivtv.xorg.cf.patch (now missing)
  • attachment:xorg-x11-6.8.2-r5.ebuild (now missing)
