Dear Dr Leslaw
How is your VGA/DVI configuration? I have connected a machine with 1024x768 resolution and here is my FrameGrabber settings: Interval between VGA signals autoadjastments: 60 secs Offset: 30 Gain: 185 From: [email protected] [mailto:[email protected]] On Behalf Of Dr Leslaw Zieleznik Sent: Thursday, December 08, 2011 1:00 PM To: Matterhorn Users Subject: Re: [Matterhorn-users] MattherHorn 1.2 and Epiphan Capture Appliance Updates and Issues -- New User Hi Reza, 0- till now, after recording more than 10 times, I couldn't manage to have the complete result of recording (Video + VGA + Audio) in Engage. You need to enable the audio and connect the microphone, it will then start recording all three streams. 1- sometimes when recording has to be finished, the server still shows that the MCA is in Capturing state. I don't understand why the status is not being updated. This is know bug, MCA sits in the capture state (the workflow is showing PAUSE) for about 35min and then will do the ingestion. In summary the device is capturing nicely if you take the above into account - see also below. There is more information about the device behave on the Matterhorn Users list. 3- almost most of the times, when the MCA ingests the file to the Core and Core starts digesting, usually it fails in 'Text Extraction" Phase. Is there any way to skip the text extraction phase while digesting? I have no problem with this, only the text OCR is not very accurate. Calendar Polling Interval: 1 minuet Agent State Push Interval: 60 seconds Ingest Interval : 2 minutes (I changed it from 60 minutes to 2 minute to speedup the ingest) I am using a similar setup: 2, 60, 5.

And it is diffucult to believe how this has happened? :) I have simply connected a microphone, activated the audio and then rebooted device, just for the purpose of testing the audio. And this somehow did trigger two streams recording. I think it means that the audio need to be enabled (!) I wonder if you can repeat the same on your device? As far as the video quality is concern, the recording quality is much better when 'independent streams' option is selected - the video quality is much worse when the 'video outside DVI/VGA' is used. By the way, I am using the f/w version v2.2.3 which I have downloaded on Monday. This has not been advertised for download yet - I am sorry Greg!

I was struggling to make it working with MatterHorn, which finally I did it, but Im facing some issues which appreciate your thoughts on that. I installed a very clean MatterHorn 1.2 on Ubuntu 10.10 server-i386 32bit, on my VMware Workstation 8 installed on my Windows 7 (host). On MCA (firmware 2.2.0e) , I configured my server URL (ie 192.168.110.87:8080) and the account username and password which was specified in my config.properties. (matterhorn_system_account, CHANGE_ME) So the first couple of hours I was trying to Register the MCA inside the Core server, which was not happening. I played a lot with URL, username and password, but no luck. So finally I ran the wireshark on my NIC card and saw that the MCA is trying to register into MCA by seding a POST HTTP request to http://192.168.110.87:8080/capture-admin/agents/rest. Finally I understood that this URL is not valid in matterhorn and is changed to http://192.168.110.87:8080/capture-admin/agents. So finally I was very lucky to find the Epiphan download page for Beta software, and I downloaded the Firmware version 2.2.3 which is a beta one. (http://www.epiphan.com/downloads/firmware/Davinci_Matterhorn/beta.php) After installation of firmware and rebooting the MCA (by the way I rebooted the MCA manually, as MCA doesn't reboot by itself after software upgrade, neither doesn't show any message for successful receiving the new firmware) the MCA registered in MatterHorn CORE. (Yes what a lovely time, at 2AM). Then I stuck in another thig which was Capturing. I was scheduling the recording, but MCA was not being informed to record. Finally I found that there is a Calendar service, which the MCA has to poll (by default every 60 minutes!) to retrieve its recoding schedule. I changed the Calendar Polling Interval from 60 minutes to 1 minute, and it fixed the problem. Now I can schedule the recordings, and MCA starts the recording. But I have some issues which seek your geeky help: 0- till now, after recording more than 10 times, I couldn't manage to have the complete result of recording (Video + VGA + Audio) in Engage. 1- sometimes when recording has to be finished, the server still shows that the MCA is in Capturing state. I don't understand why the status is not being updated. 2- sometimes after the recording, it shows the recording as Finished, but I cannot see it on Engage, it shows media is not available. 3- almost most of the times, when the MCA ingests the file to the Core and Core starts digesting, usually it fails in 'Text Extraction" Phase. Is there any way to skip the text extraction phase while digesting? 4- When I try to test the Text Analysis REST docs, I upload a image (jpeg, bmp, tif, gif) to system, but it gives me an error caused by URLDECODER because of finding the '%' (percentage) character in URL. Since the file is being POST ed to the server the URLDECODER analyses the whole file as a URL, and since file is binary, there are lots of '%' inside it. Here is the MatterHorn configuration on MCA: Calendar Polling Interval: 1 minuet Agent State Push Interval: 60 seconds Ingest Interval : 2 minutes (I changed it from 60 minutes to 2 minute to speedup the ingest) Any help, comment highly appreciated.
