2009-07-16libv4l: Make library subdir name configurablehans@rhel5-devel.localdomain
From: Gregor Jasny <gjasny@googlemail.com> While studying the Debian library package name, I noticed that private So /usr/lib/libv4l should become /usr/lib/libv4l0. As this would break existing scripts, I suggest to start versioning with the next soname bump. The line in the makefiles will then read: ifeq ($(LIBSUBDIR),) LIBSUBDIR = libv4l$(LIB_RELEASE) endif Unfortunately, the private subdirs in Debian must be named after the library package, which would be libv4l-0. Therefore I need to configure the LIBSUBDIR at compile time. Priority: normal Signed-off-by: Gregor Jasny <gjasny@googlemail.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

From: Mauro Carvalho Chehab <mchehab@redhat.com> Currently, em28xx driver outputs webcams only at RGB565 format. However, several webcam applications don't support this format. In order to properly work with those applications, a RGB565 handler should be added at libv4l. Tested with Silvercrest 1.3 mpix with v4l2grab (V4L2, with native libv4l support) and two LD_PRELOAD applications: camorama (V4L1 API) and skype (using compat32).
