2009-08-14libv4l: Do not hide JPG / MJPG pixfmt from applicationshans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> Some applications want to use jpg format if possible, so do not hide it from the apps (do not assume it always needs conversion) Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2009-08-14libv4l: Fix reqbuf Device or Resource busy error when using readhans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> Some applications such as v4l2-apps/test/capture-example.c, in read mode use select() together with read() and do a select() before the first read(). This causes issues together with certain drivers (gspca for example), do not allow switching from read mode to mmap mode and they assume read() mode if a select or poll() is done before any buffers are requested. When not using libv4l2, this is not an issue but libv4l2 uses mmap mode under the hood when converting as that safes a memcpy for each frame read. This fails with such drivers when the application has done a select() before the first read() as the driver now is in "read mode" and disallows switching to mmap mode. This patch fixes this by falling back to using read() for v4l2_read() when using mmap mode fails. Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2009-08-12libv4l: Also look for dmi info under /sys/class/dmi/idhans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> libv4l was looking for dmi strings in sysfs under /sys/devices/virtual/dmi/id but with some kernel configurations this does not exist. It turns out that the dmi strings do exist under /sys/class/dmi/id here. It seems that all systems with dmi info in sysfs have /sys/class/dmi/id so default to using that instead. To be sure fall back to /sys/devices/virtual/dmi/id (the old behavor) when /sys/class/dmi/id is not found. Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>

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>
