thanks for help

also when i delete a camera i got this error

Warning: Cannot modify header information - headers already sent by (output started at /var/www/includes/actions.php:1235) in /var/www/includes/functions.php on line 99

now i see the problem

on all /dev/video0 (0) /dev/video0 (1) /dev/video0 (2)

i have the same camera not only in montage,
if i open one by one is the same camera on all


the captura card is pico2000 with settings from wiki

solved:

increase ZM_CAPTURES_PER_FRAME to 2 instead of 1

Yeah, SOLVED (mmi, you´re a genious !)
to clarify, IMHO, a ** tip to BTTV users under 1.24.1 ** (same sittuations on SVN install under ubuntu 8.10 vanilla and excelent´s rmelin 1.24.1 livecd)

-------------------------------------------------------------
If you own a BTTV or similar card that shares 4 inputs in one chip, for example, and experience multiple monitors unstable or

** MONITORS SHOWING THE SAME IMAGES **

even that channels are correctly configured, you have to change CAPTURES_PER_FRAME under options>config tab accordingly; I set mine to 4 instead of 1 and had my 4 cheap cameras working as they should;

also, I managed to configure them using V4L2, using NTSC-M format, and RGB565 pallete, 320*240; On general tabs, use maximum fps 2 and alarm maximum 2 ;

finally, somebody already noticed (and advised the developers) that the presets for BTTV are missing many gaps and informing incorrect ones; they´ve already noticed that the problem may be seen in the preset table on the database; so I suggest you dont use presets for bttv until 1.24.2;

I cant express how I appreciate this software and its developers; hope to make a donation soon if everything goes fine ! consider U 2 !

I solved it on CentOS unchecking V4L_MULTI_BUFFER, now I have the same behaviour than 1.23.3 . I use V4Lv1
Thanks!!
