Dear vdr fellows.
For a reason not to go in details too much here, I would like to make vdr recognise sparse DVB adapter numbers.
I have:
root@vdr:/dev/dvb# ls -l total 0 drwxr-xr-x 2 root root 200 Mar 19 11:59 adapter0/ drwxr-xr-x 2 root root 120 Mar 19 11:59 adapter1/ drwxr-xr-x 2 root root 120 Mar 19 11:59 adapter5/ drwxr-xr-x 2 root root 120 Mar 19 11:59 adapter6/ drwxr-xr-x 2 root root 120 Mar 19 11:59 adapter7/ root@vdr:/dev/dvb#
But vdr uses only the first two devices.
Is there any easy possibility to patch the code accordingly?
Thank you.

I'm afraid this won't work, because VDR stops scaning for DVB devices as soon as it hits a gap.
You might want to try changing this function:
bool cDvbDevice::Initialize(void) { int found = 0; int i; for (i = 0; i < MAXDVBDEVICES; i++) { if (UseDevice(NextCardIndex())) { if (Probe(*cDvbName(DEV_DVB_FRONTEND, i))) { new cDvbDevice(i); found++; } else NextCardIndex(1); // skips this one <=========== changed line } else NextCardIndex(1); // skips this one } NextCardIndex(MAXDVBDEVICES - i); // skips the rest if (found > 0) isyslog("found %d video device%s", found, found > 1 ? "s" : ""); else isyslog("no DVB device found"); return found > 0; }
Untested, don't know if it will actually work as expected.

Good i didn't know that years ago when setting up my vdr boxes... :) IOW this approach has been working for me for quite a while w/o any problems. Note i'm still at 1.4.x and my 'gaps' actually contain adapters (unused by this vdr instance). If the gaps really are a problem you could always renumber the adapters using udev rules such as
SUBSYSTEM=="dvb", SUBSYSTEMS=="pci", KERNELS=="0000:00:0e.0", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf dvb/adapter%%i/%%s 0 $${K#*.}'", NAME:="%c" SUBSYSTEM=="dvb", SUBSYSTEMS=="pci", KERNELS=="0000:02:09.0", PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf dvb/adapter%%i/%%s 1 $${K#*.}'", NAME:="%c"
etc
