From: Hans de Goede <j.w.r.degoede@hhs.nl> * The mmap64 support in 0.3.3, has caused a bug in libv4l1 when running on 32 bit systems (who uses those now a days?), this bug caused v4l1 compatibility to not work at all, this release fixes this Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Thierry MERLE <thierry.merle@free.fr>
2008-07-08v4l2-library: libv4l-really-sync-with-0.3.4.patchThierry MERLE
From: Hans de Goede <j.w.r.degoede@hhs.nl> * The mmap64 support in 0.3.3, has caused a bug in libv4l1 when running on 32 bit systems (who uses those now a days?), this bug caused v4l1 compatibility to not work at all, this release fixes this * Some apps (xawtv, kopete) use an ioctl wrapper internally for various reasons. This wrappers request argument is an int, but the real ioctl's request argument is an unsigned long. Passing the VIDIOC_xxx defines through to the wrapper, and then to the real ioctl, causes the request to get sign extended on 64 bit args. The kernel seems to ignore the upper 32 bits, causing the sign extension to not make a difference. libv4l now also ignores the upper 32 bits of the libv4lx_ioctl request argument on 64 bit archs * Add a bugfix patch for kopete in the appl-patches dir, currently it assumes that it got the width and height it asked for when doing a S_FMT, which is a wrong assumption Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Thierry MERLE <thierry.merle@free.fr>

From: Hans de Goede <j.w.r.degoede@hhs.nl> * Add open64 and mmap64 wrappers to the LD_PRELOAD wrapper libs, so that they also work for applications compiled with FILE_OFFSET_BITS=64, this fixes using them with v4l-info * While looking at xawtv in general, found a few bugs in xawtv itself, added a patch to fix those to the appl-patches dir * Talking about the appl-patches dir, restore that as it accidentally got dropped from 0.3.2 * Be more verbose in various places when it comes to logging (esp errors) * Change v4lconvert_enum_fmt code a bit, so that it is easier to add more supported destination formats to libv4lconvert * Don't return -EINVAL from try_fmt when we cannot convert because the cam doesn't have any formats we know. Instead just return as format whatever the cam returns from try_fmt, this new behavior is compliant with the v4l2 api as documented Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Thierry MERLE <thierry.merle@free.fr>

2008-07-03v4l2-library: libv4l: update mercurial tree to latest 0.3.1 releaseThierry MERLE
From: Hans de Goede <j.w.r.degoede@hhs.nl> This patch syncs (updates) the libv4l in mercurial with (to) the latest 0.3.1 release. - Only serialize V4L2_BUF_TYPE_VIDEO_CAPTURE type ioctls - Do not return an uninitialized variable as result code for GPICT (fixes vlc, but see below) - Add an apps-patches directory which includes: * vlc-0.8.6-libv4l1.patch, modify vlc's v4l1 plugin to directly call into libv4l1, in the end we want all apps todo this as its better then LD_PRELOAD tricks, but for vlc this is needed as vlc's plugin system causes LD_PRELOAD to not work on symbols in the plugins * camorama-0.19-fixes.patch, small bugfixes to camorama's v4l1 support, this patch only fixes _real_ bugs in camorama and does not change it to work with v4l1compat. Although it does work better with these bugs fixed :) With this patch and LD_PRELOAD=<path>/v4l1compat.so it works flawless.

2008-07-01v4l2-library: libv4l1 and v4l1compatThierry MERLE
From: Hans de Goede <j.w.r.degoede at hhs.nl> libv4l1 is the base of the v4l1compat.so wrapper lib, which is a .so which can be LD_PRELOAD-ed and the overrules the libc's open/close/etc, and when opening /dev/videoX calls v4l1_open.

2008-07-01v4l2-library: libv4l2 and v4l2convertThierry MERLE
From: Hans de Goede <j.w.r.degoede at hhs.nl> libv4l2 offers v4l2_ prefixed versions of open/close/etc. The API is 100% the same as directly opening /dev/videoX using regular open/close/etc, the big difference is that format conversion is done if necessary when capturing. That is if you (try to) set a capture format which is not supported by the cam, but is supported by libv4lconvert, then the try_fmt / set_fmt will succeed as if the cam supports the format and on dqbuf / read the data will be converted for you and returned in the request format. v4l2convert: open/close/ioctl/mmap/munmap library call wrapper doing format conversion for v4l2 applications which want to be able to simply capture bgr24 / yuv420 from v4l2 devices with more exotic frame formats.

2006-12-01Fix driver_test for a non-compliance on bttv driverMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> bttv driver presents a non-compliance: When S_FMT is called, pix.sizeimage reports a different size than when QUERYBUF is called, for the same S_FMT. The current code can work fine with this non-compliance, but an error should be reported. Those are the reports from bttv driver, by running driver-test: FMT SET: 640x480, fourcc=YVU9, 640 bytes/line, 345600 bytes/frame, colorspace=0x00000000 <snip/> QUERYBUF: 00:00:00.00000000 index=0, type=video-cap, bytesused=0, flags=0x00000000, field=any, sequence=0, memory=mmap, offset=0x00000000, length=348160 TIMECODE: 00:00:00 type=0, flags=0x00000000, frames=0, userbits=0x00000000 QUERYBUF: ERROR: VIDIOC_S_FMT said buffer should have 345600 size, but received 348160 from QUERYBUF!
