I mean that the installer doesn't detect and configure matterhorn to use
the card. The card is there, linux detects it, matterhorn just doesn't
see it.
Perhaps my assumption is incorrect here, but I assume that the
matterhorn installer is supposed to detect all of the video capture
devices and configure them. It does detect the BT878. Is this
assumption incorrect?
Is the correct procedure that we now manually add the devices to the
config files?
Also you mention v4l2src...will that work with a non v4l2 source? The
output from v4l-info that pasted in, indicates it's using v4l v1 not v2.
Does matterhorn 1.4 not work with v4l v1 devices anymore?

Dear Jonathan,
I'm not sure of what you mean with "the is not detected". If it wasn't,
you'd be unable to see a /dev/video0 entry.
Mind you, the automatic entries in the /dev directory are not stable
between reboots, and depending on which driver loads first you may end
up with the Epiphan in video0 or video1 (or any other videoXXX
combination). In theory, the CA install scripts create stable symlinks
for these devices (so, for instance,/dev/screen will always point to the
Epiphan device, no matter which videoX device it is).
Anyway, even though your card *is* detected, it may still be
nonfunctional. You can check (among other methods) by typing:
> gst-launch v4l2src device=/dev/video0 ! autovideosink
If it doesn't work, maybe demsg can provide some logs of what happened.
If it works, then it's a matter of configuring Matterhorn correctly,
i.e. making sure that in
$FELIX_HOME/etc/services/org.opencastproject.capture.agent.impl.ConfigurationManager.properties,
the src property of your Epiphan card entry is pointing to the right device.
Hope it helps.
Best regards

Has anyone been able to get matterhorn 1.4-rc3 to detect the epiphan
card while using the reference agent? If so, what version of ubuntu
are you running and how did you do it?
I'm running ubuntu 10.10. I first ran the install like normal with
1.3. It didn't prompt for driver installation, which I believe is
normal now and it didn't detect the card. However it did detect the
BT878 on /dev/video0.
Figuring that since the Epiphan isn't "special" anymore, I
downloaded and installed the epiphan driver package:
vga2usb-3.27.0.3-ubuntu-2.6.__35-31-generic-x86_64.deb
The installation went without a hitch and I rebooted the agent.
When it came back up I checked to make sure vga2usb was loaded and
re-ran the install. The card was still not detected. However the
BT878 was detected on /dev/video1 this time.
Doing a v4l-info on /dev/video0 yields:
### video4linux device info [/dev/video0] ###
general info
VIDIOCGCAP
name : "Epiphan VGA2USB #V2U107134"
type : 0x1 [CAPTURE]
channels : 1
audios : 0
maxwidth : 1280
maxheight : 800
minwidth : 1280
minheight : 800
So the card is definitely there. Any help anyone can give would be
appreciated.
Thanks.
