hi list,
while i'm very happy with the Quickcam Pro 9000 on the current (checked
out yesterday) uvcvideo driver, i'm a little disappointed with the frame
rate: luvcview never reports a higher rate than 15fps for this device,
regardless of capture size: 320x240 is as slow as 960x720.
also, on the current version i can't seem to set the autoexposure to off
using the luvcvideo interface. previously i was using uvcdynctrl from
Logitech's own libwebcam, but now that reports an error:
$./uvcdynctrl --clist
[libwebcam] Unable to refresh device list. (error 12: A Video4Linux2
API call returned an unexpected error)
is there a trick to improving the frame rate? furthermore, is anyone
else having trouble using luvcvideo or uvcdynctrl to manipulate camera
paramaters?
where frame rate is concerned, it's perhaps worth mentioning that i'm
testing this on a Dual Core 2.4GHz laptop with 4GB of physical memory.
the machine hsa hardware graphics acceleration provided by an NVIDIA
Quadro FX 570M.
cheers,
Julian Oliver
Madrid, Spain
