PostPosted: Wed 18 Jul 2007, 09:07    Post subject:  XawTV video viewer  

Update July 24 2009: xawtv updated to version 4.x development snapshot 20081014

xawtv is a video viewer application, which can be used to view Video4Linux (V4L/V4L2) devices, including analogue TV tuners and webcams.
When compiled with additional libraries, xawtv can also be used with digital TV tuners (DVB devices).

Here is the "basic" version without DVB tuner support, which keeps the installer size down.

Optimal video output is via the "xv" (accelerated XVideo overlay) feature, which requires the addition of the "v4l" extension plugin for Xorg, and this xawtv package includes the v4l plugin specifically for Xorg7.3 in the Puppy 4-series ...
... but it's very important to enable this plugin: after installing this dotpet, open /etc/X11/xorg.conf in Geany.
In Section "Module" add this line
Code:
Load  "v4l"

Now restart X (or reboot).

If you still see an error relating to xv, it's possible to fall back to non-xv video display by launching xawtv like this -
Code:
xawtv -noxv

Here is the xawtv package with full digital tuner support. This includes the libmpeg2 library, since digital TV broadcasts are encoded with MPEG2.
I have also included the Zapping VBI (zvbi) library, for embedded data reading support, such as teletext.
As before, the v4l Xorg plugin should be enabled for optimal video output.

Thanks to raffy, the dotpet is here -
http://minipc.org/ipup/download/xawtv-DVB-20081014.pet

With the added libraries, the xawtv package is no longer small at 1.4MB.
The more powerful (and more useful) MPlayer starts to look like a better alternative.
Beware. The only version of MPlayer available on this forum with V4L/V4L2 input support is -
"MPlayer-1.0rc2 + mencoder Feb 2008"

MU provided a good HOWTO for using webcams with MPlayer here

For those using the older 2.x versions of Puppy, here is the basic version of xawtv. This package includes the v4l plugin specifically for Xorg7.0 in the Puppy 2-series since v2.10. This v4l plugin should be enabled as explained in the first post.

This xawtv package should work in Puppy3.x, but only by launching it without xv support -
Code:
xawtv -noxv

This is because I was unable to compile the v4l Xorg plugin for Puppy 3, probably because of the way that Puppy 3's Slackware-compatible Xorg is configured.

Regarding Skype

According to reports on the web, for certain webcams to work with Skype the v4l Xorg plugin is necessary. The xawtv packages above provide this plugin, but if you want to obtain the v4l Xorg plugin by itself without installing xawtv, it's available for Puppy 4 here -

Install xorg-dri with petget and reboot.
This has hardware accelerated drivers and opengl(glx).

Save libXxf86dga.so.1.0.0 to /usr/X11R7/lib, then create the missing symlink.

Thanks Muggins, I followed your instructions and downloaded the file, then created a symlink with the new name by right clicking in rox..."link...". I then tried again

Code:

# xawtv
xawtv: error while loading shared libraries: libXaw.so.8: cannot open shared object file: No such file or directory


Following the same logic, I found a file in the same folder (/usr/X11R7/lib/libXaw7.so.7.0.0) and created a symlink called libXaw.so.8 to it, suddenly xawtv sprung to life with some warnings.

Code:
# xawtv
This is xawtv-3.95, running on Linux/i686 (2.6.25.16)
xinerama 0: 1280x1024+0+0
WARNING: Your X-Server has no DGA support.
/dev/video0 [v4l]: no overlay support
v4l-conf had some trouble, trying to continue anyway
ioctl: VIDIOC_QUERYCAP(driver="";card="";bus_info="";version=0.0.0;capabilities=0x0 []): Unknown error 515
Warning: Cannot convert string "7x13bold" to type FontStruct
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct
Xlib:  extension "GLX" missing on display ":0.0".


The display worked very well here with the low light in the room at the moment. Very Happy

However when I try and run skype I get some sort of picture, but it is definetly not displaying properly (see attachment). Probably something to do with proprietary code?

This is xawtv-3.95 ...

It seems you installed the older version 3.95, which I explained should only be used in Puppy versions up to 3.x.

I provided a Puppy4-compatible version a few posts down, but wait, don't install it yet. I see that there is newer source code available, so I will revise the XawTV packages in the next few hours.

Oops! Confused Embarassed

Thank you for the new version of xawtv, and clarifying the versions, I will be giving it a spin. It has more features than I realised besides watching webcams.
