Hans de Goede 8ad0509a1c v4l2: get_nearest_size: Always reinit all struct fields on retry They may have been modified by the ioctl even if it failed. This also makes the S_FMT fallback path try progressive first, making it consistent with the preferred TRY_FMT path. https://bugzilla.gnome.org/show_bug.cgi?id=735660		2014-08-29 16:14:56 -04:00

v4l2 plugins
============

The idea is a bit the same as the idea for the v4l1 plugins. We want
one generic v4l2element, and a few child objects (probably only two:
v4l2src and v4l2sink):

                /-------- v4l2src
v4l2element ---=
                \-------- v4l2sink

Both v4l2src and v4l2sink have a uncompressed and a compressed
recording-/playback-mode. Since this is all part of v4l2, the 'client'
of these elements, i.e. an application using v4l2src/v4l2sink, will
hardly notice this. All capsnego stuff is done inside, and the plugin
knows which formats are compressed and which are not.

Please note that the v4l1 and the v4l2 plugins are *not* compatible
concerning properties. Naming has been kept the same where possible,
but in some cases, properties had to be removed or added to make
full use of v4l2.
