Hi,
I am trying to transfer digital video over firewire from my camera
(Canon MXV200, PAL) to my laptop using fwcontrol, but whenever I try I
get something like this:
# fwcontrol -R tmp/test.dv
(EAGAIN)
(EAGAIN)
fwcontrol: unknown format 0x1e
If I first press play then run the command I get:
# fwcontrol -R tmp/test.dv
PAL
0fwcontrol: unknown format 0x1e
The format code sometimes varies, and I have also got input/output
error. Repeating can cause system to crash! or other applications to
coredump.
Trying with "sysctl hw.firewire.try_bmr=0" as suggested in the man-page
does not change anything.
I have tried to use dvrecv and it correctly identifies the camera/model
but fails to read a single frame.
What am I missing?
Thanks, Erik
