Hello,

I am new to ffmpeg and I am having some trouble using my libdc1394
supported webcam with it. I keep getting the same error:
----
[libdc1394 @ 0x1722520] Can't find matching camera format for uyvy422,
320x240 at 29970:1000fps
hw:0,0: Operation not permitted
----

Here is some build info:

ffmpeg version N-47291-g0b14c19 Copyright (c) 2000-2012 the FFmpeg

  libswresample   0. 17.101 /  0. 17.101

libdc1394 version is 2.2.0

Camera is Chameleon CMLN-13S2C

Does anyone have any idea as to what I could be doing wrong?

Thanks,
Bryan
