Greetings all,<br>
<br>
I have just started messing with the video in on my Linux laptop and have encountered some problems with Gem:<br>
<br>
*The OS is Ubuntu Hoary, Pd 0.38, and Gem 0.90.<br>
<br>
*I am using ADVC-100 ieee1394 interface which allows me to connect any
S-Video device to my laptop. The device works fine with Kino (dvgrab).<br>
<br>
*My /dev folder includes /dev/raw1394 and /dev/video1394/0<br>
<br>
*All of the stuff is installed TTBOMK properly.<br>
<br>
*When using Gem, I cannot get the video to work as I do not have v4l
devices available (/dev/video0) with this device, and the ieee1394
devices Gem looks for under /dev/ieee1394/dv/host<x>/<y>/in
which obviously fails on my system. The exact error in the terminal is:<br>
/dev/ieee1394/dv/host0/PAL/in: No such file or directory<br>
<br>
*I tried linking /dev/raw1394 to /dev/video0 (I am not sure as to what
is the difference between the two, so this may have been
stupid--nonetheless I tried it just to cover all possibilities) and
then using ../gem/examples/04.video/00.SimpleVideo.pd tutorial
generates one complaint: get capabilities: Invalid argument and I get
no video. All permissions should be properly set on the devices/links
(root:video 660).<br>
<br>
*I tried using latest vloopback driver (0.97) and when I modprobe it, I
get /dev/video0 and /dev/video1 devices (81,0). However, connecting to
them yields following in PD:<br>
<br>
video4linux<br>
ieee1394 for linux<br>

now trying standard palette 0<br>
closing video<br>
pix_texture: not using client storage<br>
<br>
In addition, the terminal also spits out: VIDIOCMCAPTURE: Invalid argument<br>
<br>
*I tried using dc1394_vloopback with various settings including:<br>
dc1394_vloopback --video1394=/dev/video1394/0 --vloopback=/dev/video0<br>
but that simply tells me "no cameras found :(" no matter what settings
I try (I also made sure that the vloopback driver was unloaded).<br>
<br>
I am not aware of any other way to bridge ieee1394 feed and v4l, nor am
I sure as to how to force pix_video to use different ieee1394 source
(not sure whether this even works with the advc-100).<br>
<br>
*I tried accessing Gem CVS to see if there were any changes since the 0.90, but the CVS seems to be inaccessible:<br>
cvs -z3 -d:pserver:anonymous@cvs.gem.iem.at:/cvsroot/pd-gem login<br>
Logging in to :<a href="http://pserver:anonymous@cvs.gem.iem.at:2401/cvsroot/pd-gem" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">pserver:anonymous@cvs.gem.iem.at:2401/cvsroot/pd-gem</a><br>
CVS password:<br>

<br>
So, I have pretty much run out of ideas and I was hoping that someone might be able to help me out with this one, namely:<br>
<br>
1) Is there a way to use my ADVC-100 to stream video to PD/Gem?<br>
2) If there is no native way to do that is there a way to use vloopback
or some similar method to channel its feed into the v4l format?<br>
3) any other ideas/suggestion (other than spending money and buying myself a new <whatever> :-)<br>
<br>
I would greatly appreciate assistance in this matter!<br>
<br>
Best wishes,<br>
<br>
Ico<br>
