The division in v4l2* plugins is the same as for v4l1 - i.e. an element, a src and a sink, but there won't be separate encoding plugins (like v4lmjpegsrc) - all functionality is (thanks to video4linux2) integrated in one plugin: v4l2src. v4l2sink is still to be done, that'll come later. --- sys/v4l2/README | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 sys/v4l2/README (limited to 'sys/v4l2/README') diff --git a/sys/v4l2/README b/sys/v4l2/README new file mode 100644 index 00000000..f10c27c2 --- /dev/null +++ b/sys/v4l2/README @@ -0,0 +1,24 @@ +v4l2 plugins +============ + +The idea is a bit the same as the idea for the v4l1 plugins.
