USB WebCam and MJPEG instead of YUYV

[ris2t]

Is it possible to configure zoneminder 1.25.0-1 (Ubuntu 12.04 version) to utilise MJPEG from locally attached USB camera's rather than YUYV palette.

Currently I'm hitting USB memory and resolution limits when attempting 3 web cams and one extended via an USB RJ45 extension adapter.

Using luvcview or guvcview I can have all 3 streaming utilsing MJPEG but under zoneminder and YUYV palette 1 of the 3 camera's fails.

Also hitting issues with the USB extension dropping out the YUYV capabilities or reducing its quality significantly but not impacting MJPEG format as much.

------------
http://sourceforge.net/projects/mjpg-streamer/ - I'm aware of MJPEG-Streamer but hoping for native configuration within zoneminder.

http://www.zoneminder.com/forums/viewto ... =USB+MJPEG - this patch looks to have promise. Can any one confirm?

Example error (from non RJ45 extended webcam). I've confirmed its ok when I unplug one of the other USB web cams so its definitely the USB memory limits. I'll attempt to juggle controllers to balance but its only one part of the puzzle/problems.

Example below of the capabilities that drop via the extension hinting that MJPG is a better choice over YUYV.

I can confirm mastertheknife's patches for 1.50.0 work for my questions. MJPEG instead of YUYV from the USB webcams. Must better quality over the RJ45 extension. Still got no space left on device errors with 3 cams but rejigging the controllers they're plugged into should address that.

Install took a few attempts. Here are some of my notes.

Tried to map to the default ubuntu paths, although /usr/local is more correct I wanted consistency with what I know.

Code: Select all

./configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --datarootdir=/usr/share --sysconfdir=/etc/zm  --with-libarch=lib64 --with-webdir=/usr/share/zoneminder/ --with-cgidir=/usr/share/zoneminder/cgi-bin --with-webuser=www-data --with-webgroup=www-data --enable-mmap=yes

perl module still installed in /usr/local/share/perl/5.14.2, couldn't find a switch for them.

/etc/zm/apache.conf - had to manually add ScriptAlias to get around the follow errors and live camera not streaming over web.
