Well, there is a work around

that at least works for me :-)

the only change is 

in func -> gst_v4l2src_grab_frame

- need_copy = v4l2src->pool->num_live_buffers == v4l2src->pool->buffer_count;
+ need_copy = index == 0;

this way, the copy always happens to the first buffer (so it will always be
available to the driver)

and the other buffers are in use too.

....Well, since it is a driver bug, it is hard to say if the driver is really
writing to pool->buffer[0] or it is writing to another buffer in pool and just
returning buffer.index = 0 to us.

Wim, what do you think?

btw: I've tried to make my camera to use 4 buffer but it just uses 2 buffers (I
have no idea about other drivers).

BR,
Edgard
