V4L2 Support with ZoneMinder 1.22.x

[slbpatrol]

I have managed to get some code for V4L2 support. I have re-written portions of ZoneMinder to support V4L2. If anyone is interested in helping me test it I will be glad to send you the code. I currently have two Logitech Cameras, Logitech Orbit (V4L and V4L2) and Logitech Orbit MP (V4L2 only). I have removed support for V4L (unless someone knows how to allow both or write code to allow both). I am trying to determine why the MP only shows at 176 x 144. I believe it has something to do with the uvc driver.

Hi,

I also have the orbit with uvc drivers. I can do some testing and help.
I am currently working on improving the uvc_stream software to allow camera control (actually got that working lastnight)

See my post here

My way is a workaround, been waiting for the v4l2 support, and can try and help. Not a C developer, but do Delphi, but I can get my way around the c, just takes a bit of googling to get to understand the command syntax.

If you make the code available for download somewhere. (or even better, some kind of version control repo ? (subversion?)

[slbpatrol]

You can get the development code from here:

http://home.triad.rr.com/metslb/webfiles/

I do not know how to use svn repositories yet.

I have determined that the Logitech Quickcam MP (046d:08cc) uses two formats, YUYV and MJPEG. The YUYV will only display the images at 176x144 while the MJPEG allows up to 640x480. I am currently looking for code the will convert from mjpeg to rgb24. I have seen come code that will do this but it is part of an application that seems to include serval files. All I am interested in is the mjpeg to rgb24 conversion. If anyone has any code or that can point me into the right direction I will greatly appreciate it.

Hi, will grab the code soon, and have a play. I just finished adding functionality to uvc_stream (by Tom Stoeveken (http://naaa.de/uvc_streamer.htm) to allow motor control, waiting to hear what he thinks.

If you have a look at his code (it streams jpeg at 640x480), it may give a clue what is needed.

Won't actually get to your code in a few weeks, as I have two websites that I have to complete, so my free time has now become limited for a while

I have a couple newer Logitech cameras that only work via the uvc_streamer hack... would love to see native support. Any progress?

I have finally incorporated V4L2 support for Zoneminder. Please feel free to test the development source at http://mysite.verizon.net/brownslb/zoneminder/.

Dear slbpatrol,

Thank you for developing the v4l2 support to Zoneminder, and leave me
a message in the zoneminder forum. I tested the latest version which
is ZoneMinder-1.23.1a.devel.tgz downloaded from your site
http://mysite.verizon.net/brownslb/zoneminder/. However, it can't pass
through the Make.

sudo ./configure --with-webdir=/var/www/html/zm
--with-cgidir=/usr/lib/cgi-bin --with-webuser=www-data
--with-webgroup=www-data --with-ffmpeg=/opt

goes perfectly, and I've installed the mjpegtools from synapic pkg
manager beforehand.(and also I tried from source, the same)

but when I do the
sudo make, I got

"
make all-recursive

" and I couldn't go on. where do you think the problem is? I did a
google on PixelFormats.c error, but no supports on that.

Thank you for your reply. My Logitech AF (064d:0994) is still sleeping
on my desktop

Best Regards,

hey, any clues on how to solve that last make problem?

I am installing zoneminder for my job, and time is short, and i cant seem to find the problem?

[solidd_swa]

so, i was debugging. and found that
PixelFormat.c (or .h) was missing #include <stdint>
that solved the first error.

and for some reason when i put #include "huffman.h" in the .h file, it solves the other 2 problems.

but now, i am faced with this

any ideas? its way beyond my scope here

[only4john]

instead of using ./configure, but use ./configure.sh (edit it first to fit your needs), it may solve all the problems.
