This probably isn't the best time to ask for additional features :) but
next to an option to see the actual recordings on the device and
manually ingest them it would be great to have an option to start
unscheduled recordings from the device.
If the ECD has those functionalities, and works reliable and consistent,
it would be a great option for lecture captures with opencast. At the
moment however I feel we payed a lot of money for a device that does not
function as advertised and in fact isn't even usable.
Hopefully there will be some major improvements and the device will be
usable, cause on paper it's a great device, with huge potential.

I have more or less the same remarks, please see my last
correspondence. In summary:
1. there is only one stream processed the VGA or DVI, and the
'selection' by core is random (?)
2. 1h30 min recording has failed for me too, and strangely enough it
was process by the server but nothing came out
3. <<<The fact that there is no way to see the files on the ECD and

And not only for you! You just have confirmed that captured
recording can be lost and unrecovered.
I think the feature of accessing the device storage with option
of uploading the last capture to the server, is obsolutely essential.
I am only repeating what I have already said.
Without this feature, this device is practically useless.
4. <<<This experience leads us to wonder if this machine is production

Well, it is certainly not! In the current state I would not dare
to use it even in a pilot project.
The question is what next?
I am now very pessimistic about the progress. Or the device hardware
is not up to the job - Greg complained about the memory size? Or the
software has not been properly designed from the start?
I've got a feeling that Epiphan will release truly own MH compatible
capture device. The Lecture Recorded 2
http://www.epiphan.com/products/recording/lecture-recorder-x2/
they have released last autumn makes me think.
Let's hope and wait or try something else?

Hi all,
Yesterday we tried to use the ECD in a production environment,
confident that the hard and software was mature enough to do some
recordings in an actual class environment. Our experience however was
everything but satisfactory and led us to do a last minute replacement
of the ECD with the default opencast capture agent.
We found that since the last firmware ( the one for download on
epiphan site and the one provided by Greg on the list here ) only 1
stream is processed on the server. The recordings we made only show
the video stream in the engage player, however the original file on
the server shows a multistream avi with 3 streams. This problem is
inconvenient but not that problematic since we could recover the
original multistream ( hopefully we can recover the independant
streams from the avi ). The following recordings had more major
problems. We had to do 3 recordings in a row, one 30 minutes long (
which we can recover from the server ) and 2 following that of 1h30
that both failed.
The second recording disappeared from the capturing list on the admin
server after some minutes, and went to processing, resulting in an
empty directory on the server. The recording had more than 1 hour to
go at that point. The third recording started successfully and changed
status to sending for processing ( or something similar ) after less
than an hour, more than 30 minutes needed to be captured at that
point. This recording was unrecoverable as well, since there is no way
to access the files on the ECD and see what is actually happening on
that machine.
This experience leads us to wonder if this machine is production
worthy and if anyone is using this in a reliable way. We understand
that this is still in active development but also believe that basic
functionality and reliability should be expected. The fact that there
is no way to see the files on the ECD and download them from the
device in case something goes wrong is also a big problem for us,
questioning the fact if we can rely on this in a production environment.
Maybe someone on the list can shed some light on what to expect from
the device in the future and if someone has different experiences with
this, please let us know. At the moment we don't feel confident to use
this device in any classroom environments.
Thanks
