libv4l release: 0.5.1 (The Skype release)

libv4l release: 0.5.1 (The Skype release)

[Hans de Goede]

Hi All,

After much frustration about the very poor implementation of v4l in skype, I'm 
happy to announce libv4l-0.5.1, in which after much pain, I've managed to 
implemented a fix for the skype problem in a way which does not make me feel dirty.

libv4l-0.5.1
------------
* Add support for software cropping from 352x288 -> 320x240 / 176x144 ->
   160x120, so that apps which will only work with vga resolutions like
   320x240 (Skype!) will work with cams/drivers which do not support cropping
   CIF resolutions to VGA resolutions in hardware. This makes all 2.6.27 gspca
   supported cams, except for the pac7302 which only does 640x480 (and skype
   wants 320x240), work with skype
* The v4lconvert_convert function was becoming a bit of a mess, so split the
   functionailiy into separate v4lconvert_convert_pixfmt, v4lconvert_rotate and
   v4lconvert_crop functions, and make v4lconvert_convert a frontend to
   these
* Do not link the wrapper libs against libpthread (patch from Gregor Jasny)

With the just submitted ioctl compat patch, this works even with 32 bit
Skype on 64 bit Linux. The soon to be available Debian packages will
provide a cross compiled version of your lib, too. There's a public git
repository available at: http://git.debian.org/?p=collab-maint/libv4l.git

Thanks for your highly appreciated work,
Gregor

libv4l release: 0.5.1 (The Skype release)

[Hans de Goede]

Hi All,

Nothing special just a small bugfix release mainly fixing some bad interactions 
between the pwc driver and libv4l (due to pwc driver bugs). More in general 
this release makes libv4l more robust against drivers who promise they can 
handle foo when calling try_fmt and then actually give you bar when you do a s_fmt.

libv4l-0.5.2
------------
* Add Philips SPC210NC to list of cams with upside down sensor, reported by
   Rieker Flaik
* Work around some drivers (pwc) not properly reflecting what one gets after a
   s_fmt in their try_fmt answer
* Check that s_fmt atleast gives us the width, height and pixelformat try_fmt
   promised us, and if not disable conversion
* Only check width, height and pixelformat when checking if we are doing
   conversion, instead of doing a memcmp, as that are the only things which
   the convert code checks
* Take into account that the buffers only contain half of the lines when
   field is V4L2_FIELD_ALTERNATE
