[Ffmpeg-devel] Problem using ffmpeg with v4l

[Flavio Pimentel Duarte]

I am having problems to capture from USB webcam model Creative Notebook, 
but I think this problem is not restricted to this model. Capturing movies 
using this webcam generates a very dark movie. I've made several tests 
using both mplayer and motion programs and during the tests I noticed that 
starting mplayer using the webcam as source prior to use ffmpeg sometimes 
solves this problem. This particular behavior made me think it should be 
an initialization problem. The program motion also generates dark pictures 
with the default configuration, but the option auto_brightness seems to 
fix the problem.
 	Does anyone have suggestions to deal with this problem ?
