Hello, I had promised Ronald I'd write a small guide for using this driver under Debian, so here it is : I'd like to be published because some people can probably find it useful, please append a nospam- to my email address if you decide to put it somewhere. I didn't know if you used sgml so I quickly wrote it, I can always reformat it later... Let me know if you find it useful, Thanks seb
Setting up the modules ------------------------------------- First of all, you'll probably need to compile the drivers yourself, the kernels available in Sarge (currently known as "testing") are 2.4.2X, the 'dc10' driver didn't work for me. For some reasons I ignore, these drivers requires /lib/modules/`uname -r`/build to point to the directory where your kernel was built It's a symbolic link here: # ls /lib/modules/`uname -r`/build -l lrwxrwxrwx 1 root root 14 2004-01-04 18:21 /lib/ modules/2.4.20-3-k7/build -> /usr/src/linux Then you should download the modules' sources there: http://prdownloads.sourceforge.net/mjpeg/driver-zoran-0.9.4.tar.gz?download # tar -zxf driver-zoran-0.9.4.tar.gz # cd driver-zoran-0.9.4 # make # make install now you need to add an entry to your modules.conf, we'll do this using modutils: create a file /etc/modutils/video containing : alias char-major-81 zoran options zoran card=1 v4l_bufsize=2048 pre-install zoran (modprobe saa7110; modprobe adv7175; modprobe zr36060) then run update-modules to regenerate /etc/modules.conf - card=1 is because I have a new model, you can find the appropriate number for other versions there : http://mjpeg.sourceforge.net/driver-zoran/cards.php - v4l_bufsize=2048 indicates the size of the reserved bigphys buffer, it's enabled by default in Debian kernels (CONFIG_BIGPHYS_AREA=y), so all you need to do is to add to your append line in /etc/lilo.conf a bigphysarea parameter with the buffer size, this way the kernel will reserve this amount of memory as video buffer More informations about bigphysmem can be found here : http://www.polyware.nl/~middelink/En/hob-v4l.html#bigphysarea here's mine : append="hdc=ide-scsi hdd=ide-scsi max_scsi_luns=1 bigphysarea=2048" Don't forget to run lilo again, and reboot, because the kernel seems to need this to reserve memory. statistics are available there : # cat /proc/bigphysarea Big physical area, size 8192 kB free list: used list: number of blocks: 1 0 size of largest block: 8192 kB 0 kB total: 8192 kB 0 kB (I have no clue why it looks bigger) This will enable you to capture stills JPEG using xawtv for example. Video playback in real time -------------------------------------------- mplayer has a feature which will let you play your videos directly to the tv, which was supposed to be impossible unless you used a MJPEG codec all you need to do is to get mplayer here : http://www1.mplayerhq.hu/MPlayer/releases/MPlayer-0.92.tar.bz2 # tar xjvf MPlayer-0.92.tar.bz2 # cd MPlayer-0.92 # ./configure --enable-zr # make # make install then you can run mplayer with the special video output : # mplayer -vo zr somefile.avi you can also scale it to remove "black lines" : # mplayer -vo zr -sws 0 -vop scale=384:204 file.avi see man mplayer for further informations _____________________________________________________________________ Envie de discuter en "live" avec vos amis ?
