I guess this is a v4l bug. We've found several memory leaks on em28xx driver, fixed at the development -git: http://git.kernel.org/?p=linux/kernel/git/mchehab/devel.git I'll do some tests again with the latest em28xx driver to double check if it is there any other memory leak. If not, then we could replicate the same approach into uvcvideo.
