v4l howto and help request
Hi! This is a short guide on how to build webcamd and a request for help. webcamd is a port of Linux v4l drivers as a system daemon. I'm tryng to get it working so that I can migrate my desktop someday. Webcam support is mandatory or my sister will be upset ;-) Here are my steps: 1. Install libusb2 8.1-5 or later (to fix bug #594330) 2. Download kernel source. Put it in /usr/src/sys 3. ln -s x86_64 /usr/src/sys/amd64 4. Download fetch script from bug #594483 and put it in your path 5. Add /usr/lib/freebsd to your path 6. Build cuse4bsd as in step 3 in http://www.selasky.org/hans_petter/video4bsd/ 7. kldload cuse4bsd.ko and copy the library to /usr/lib 8. Build webcamd as in step 4 in http://www.selasky.org/hans_petter/video4bsd/ But then when I run webcamd, get this weird error: Attached ugen0.2[0] to cuse unit 0 webcamd: malloc.c:3097: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) ((av)-bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd old_size == 0) || ((unsigned long) (old_size) = (unsigned long)__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) ~((2 * (sizeof(size_t))) - 1))) ((old_top)-size 0x1) ((unsigned long)old_end pagemask) == 0)' failed. Aborted Heap corruption maybe? I also obtained a gdb backtrace. It seems that this is something related with threads. What does sigsuspend do? Is the problem with handling of this signal or is the signal itself something that shouldn't happen? This part really gets me confused. Some help would be nice! Thanks a lot backtrace Description: Binary data
Bug#594483: BSD fetch
Package: freebsd-utils
Version: 8.1-1
Severity: wishlist
Hello there!
I've been playing with webcamd from video4bsd project to see if I can get my
webcam to work on kFreeBSD, but to run the make fetch target I was missing the
BSD fetch command.
BSD fetch is a lot like wget which is already present in GNU/kFreeBSD, so I
wrote a small wrapper like the one in /bin/mount. I figured you could include
it in freebsd-utils if it can be useful to other users.

Bug#594330: libusb2 doesn't detect any devices
Package: libusb2
Version: 8.1-3
Severity: grave
Tags: patch
Hi!
libusb2 is unusable because libusb_get_device_list doesn't detect any devices.
This happens because libusb20_be_alloc_ugen20 is disabled.
This problem can be reproduced with lsusb from
http://code.google.com/p/segin-utils/source/browse/trunk/freebsd-utils/lsusb-libusb.c.
I'm providing a patch.

Bug#594183: can't build kernel modules
Package: freebsd-buildutils
Version: 8.1-1
Severity: normal
Hi there
I was trying to build cuse4bsd and freebsd-make gives this critical error:
cd: 1: can't cd to /usr/src/sys/x86_64/include
Kernel sources are in /usr/src/sys, but freebsd-make is looking at the wrong
directory. the directory for amd64 headers is /usr/src/sys/amd64/include. I had
a look at the included makefiles, and it seems the problem originates with
${MACHINE} variable which is x86_64 instead of amd64.
cuse4bsd has other problems, which I'm workng on, but you can reproduce this
with attached makefile.
Cheers
