Depends. If the patch id big (>a few tens of kB), it would be better to
put it on a website and post the link here. Otherwise, your post will be
moderated, which could take some time.

Well, that suppose to read from several inputs at the same time. That's
only possible, as an experimental feature, in the svn version. Moreover,
I'm not sure this is currently working with http and v4l streams. This
is likely to lead to mis-alignement, because of buffers in the camera
and in VLC. You can set the size of these buffers on VLC side, btw.
