4 The idea is a bit the same as the idea for the v4l1 plugins. We want
5 one generic v4l2element, and a few child objects (probably only two:
12 Both v4l2src and v4l2sink have a uncompressed and a compressed
13 recording-/playback-mode. Since this is all part of v4l2, the 'client'
14 of these elements, i.e. an application using v4l2src/v4l2sink, will
15 hardly notice this. All capsnego stuff is done inside, and the plugin
16 knows which formats are compressed and which are not.
