Hello, I would like to use 5 bt8x8 cards (Avermedia EZCapture) on a Pentium 4. Just for video capture, no TVs, no RADIOs, etc.... I'm working on a 2.2.18 kernel. I have enough PCIs already, and I believe there should be no problem in using IRQ sharing with the bttv2 driver. It seems obvious to me I must do a lot of changes on the driver, not just changing the define BTTV_MAX. I've changed the sources everywhere it seemed necessary (vector variable inicialisation, constants, etc.), but I can't make it work. Here's what I've chaged: 1. file "bttv-cards.c" declaration: card[BTTV_MAX]={-1,-1,-1,-1}; is changed to : card[BTTV_MAX]={-1,-1,-1,-1,-1}; (i've done the same for the variables "pll" and also "tuner", just to avoid problems, because I don't use the tuner) should I change something else on this file? For example, on the /* insmod options */ block, by changing the MODULE_PARM lines? 2. file "bttvp.h" declaration: #define BTTV_MAX 4 is changed to : #define BTTV_MAX 5 should I change someting else on this file? The MAX_OPENS and/or the MAX_VBI _OPENS declarations? 3. file "bttv-driver.c" declaration: static unsigned int radio[BTTV_MAX] = {0,0,0,0}; is changed to : static unsigned int radio[BTTV_MAX] = {0,0,0,0,0}; declaration: static int bttv_video[BTTV_MAX] = {0,1,2,3}; is changed to : static int bttv_video[BTTV_MAX] = {0,1,2,3,4}; declaration: static int bttv_vbi[BTTV_MAX] = {224,225,226,227}; is changed to : static int bttv_vbi[BTTV_MAX] = {224,225,226,227,228}; (???) declaration: static int bttv_norm[BTTV_MAX] = {0,0,0,0}; is changed to : static int bttv_norm[BTTV_MAX] = {0,0,0,0,0}; again, should I change someting else? The file is *REALLY* huge! Thank you for your help. I can already open the device /dev/video4, but I can't get any video!! Bye, Bernardo |
