We correctly indicate the field ordering on interlaced buffers, but fail to flag them as containing interlaced video, which we need to do here because we signal interlace-mode=mixed in our caps. This means that downstream elements (like vaapipostproc from gstreamer-vaapi) don't recognise these buffers as in need of deinterlacing. Fix this by setting the interlaced flag on all interlaced buffers. Signed-off-by: Simon Farnsworth <simon.farnsworth@onelan.co.uk> https://bugzilla.gnome.org/show_bug.cgi?id=724899 |

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.
