Original commit message from CVS: * sys/v4l2/v4l2src_calls.c: (gst_v4l2src_probe_caps_for_format): If VIDIOC_ENUM_FRAMESIZES is defined (= recent kernel), but the corresponding ioctl() call fails even though the driver claims to support this format, just fall back to the pre-2.6.19 kernel routine that creates caps with suitable height and width ranges (see #448278).		2007-11-13 17:19:13 +00:00

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.
