Use v4l2-ctl -L to list the options (including bitrates) and set it with

Hmmm, when I run it, this is what I see:
$ v4l2-ctl -L
brightness (int) : min=0 max=255 step=1
default=128 value=128
contrast (int) : min=0 max=127 step=1
default=68 value=63
saturation (int) : min=0 max=127 step=1
default=64 value=63
hue (int) : min=-128 max=127 step=1
default=0 value=0
volume (int) : min=-15 max=15 step=1
default=0 value=11

y_offset_even_field (int) : min=0 max=128 step=0 default=0 value=0
automute (bool) : default=1 value=0
No sign of bitrates...

You should get a section below this names "MPEG Encoder Controls".
What does v4l2-ctl -c video_bitrate=8000000 and v4l2-ctl -C
video_bitrate give?
Attached is the whole section I get with ivtv-0.9.0. Can you also post
the ivtv init?
