|
|
Hi, I've been using UFOCapture to track lightning strikes for a while now (work related).
We are building up a new system to do a lightning study for a customer and we are using some HD capture cards we had around from another project.
When I try to connect UFOCapture to the card, it gives me an error UM012: Media type not matched.
At first I thought it was the 64 bit OS we are using so I backed up and put an older card in I had from testing and it attaches just fine in 640x480.
I'm assuming it has to do with the resolution, but if I try setting the Xi and Yi settings to anything other than 640x480, I get the error. ( I was trying the camera resolution of 768x494)
So:
Does UFOCapture support resolutions other than 640x480?
Has anyone tried using HD capture cards with UFOCapture?
Thanks in advance.

Hi Tommy
UM012 happens when the negotiation between UFOCaptureV2 and the device driver of video capture device on DirectShow interface was failed.
It checks Xi,Yi,Fps and inner video format name(like fourcc code).
UFOCaptureV2 supports Xi,Yi up to 1920x1200, and almost any Fps, but the inner video format is restricted one of follows.
UYUV,YUY2,I420,IYUV,YV12,DVSD,DVHD,RGB8,Y800 (un-compressed formats only)
There are some users who runs Full Pal 720x576, or 1280x1024 Y800.
I guess that your device driver support none of them on DirectShow interface.
As for HD video, there are very few capture devices that gives un-compressed video format.
(As far as I know, Imaging Source devices only).
What is your HD capture device? |

It's this one:
http://www.sabrent.com/#itemID=150§ion=Product&itemName=TV%20TUNERS
The other system I built uses another Sabrent card so I thought it would be a fairly easy thing to do... We were hoping to use higher resolution and higher speed cameras when catching lightning.
I'm not sure how to tell if any device supports the internal video formats you list...I guess I got luck with those first cards. |
