Original commit message from CVS: This patch fixes some issues caused by design issues in video4linux, adds some nicety to video4linux2 plugins and does some more evil stuff: * video4linux doesn't tell us which formats are supported by a card, so the only way to know this is by simply trying it out. This patch adds that. * v4lmjpegsink didnt have a bufferpool yet - is integrated now. * all copy() bufferpool functions have been removed since they're not needed. * v4lmjpegsink doesnt have a free() function, because hen playing the frames, all this is already handled. When the frame is not played, nothing has to be done. In total, the function is not needed. * adds a get_caps() function to v4l2src * some minor crap		2002-09-20 09:28:46 +00:00

README

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 applicaiton 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.
