I also find the current situation rather confusing. What exactly is *the* multiproto driver I should use when (soon) starting to adopt the various patches to VDR regarding DVB-S2 etc.? It would be nice if ther was a central repository (at linuxtv.org?) where *the* driver could be downloaded, just as it was in the good old days...

So I guess for VDR it will be ok to assume that a device with several frontends can only actually use one frontend at a time. Otherwise there would have to be some way of querying the device how many of the frontends can be used in parallel. But AFAIK there is no such facility in the current DVB driver API, or is there?

[linux-dvb] How to handle multiple frontends?
I'm wondering how an application is supposed to handle devices with multiple frontends. Let's assume a device that provides dvb/adapter0/frontend0DVB-S dvb/adapter0/frontend1DVB-T so that it can receive both DVB-S and DVB-T. Does this mean that it can simultaneously receive one DVB-S transponder and one DVB-T transponder? Or can it receive either a DVB-S *or* a DVB-T transponder, but not both at the same time?

[linux-dvb] Missing dependencies in *.ko files
I'm using a modified version of the v4l/scripts/rmmod.pl script to be able to state only the high level driver modules I know I need to load, and have the script find out what other modules these depend on and automatically load them, too, as in rmmod.pl load dvb-ttpci budget for a system with full featured and budget DVB cards. See ftp://ftp.cadsoft.de/vdr/Developer/rmmod.pl for my version of the script If I use the latest driver from http://linuxtv.org/hg/~endriss/v4l-dvb-av7110-refactoring there are apparently dependencies missing in some *.ko files, so my script can't find out which additional modules to load. For example, /sbin/modinfo -F depends dvb-ttpci.ko returns dvb-core,saa7146,i2c-core,saa7146_vv,dvb-core,ttpci-eeprom,firmware_class while in the driver version as of 2006-11-04 it returns dvb-core,saa7146,stv0299,i2c-core,saa7146_vv,dvb-core,ttpci-eeprom,ves1x93,stv0297,sp8870,tda8083,ves1820,firmware_class,l64781,lnbp21 Is there something wrong, or am I missing something here?

The whole HDTV thing is of no interest to me until there is a DVB card that can actually replay HDTV in hardware. Until then I'm not going to spend any time on this.

from an application point of view it makes more sense to follow the model:
decode_pat()
foreach program

decode_pmt() ==> identify the codec used by the stream_type

Moreover, the pes headers in mpeg2 are already overbloated with 90% of

But IIRC the current policy is to use the PMT only to make channel.conf and then to use channel.conf. So etheir you add more information in channel.conf (video encoding), etheir a more sane solution (which is done by mythtv AFAIK) is to put in channel.conf only tuning information + service_id + extra information (name, ...) and when you swith to a channel, you use PAT to discover your channel PMT pid, and you use PMT to discover media (video, audio, ...) pids and types (mpeg2, h264, ...). I don't like that because when I switch to a channel I don't want to first have to parse all kinds of tables, that would slow down channel switching. The second solution is also usefull when recording channel, because player will need PMT or something that describe the content of the stream.

Well, apparently this is a firmware problem - and, shame on me, one
I created myself...
Back in 2003 I was debugging problems with CAM access, and my findings
then were that if the CiMAX version 2.0 chip's registers were read too
often, this caused frequent failures. So I changed that to no longer
read the CiMAX registers once a CAM has been detected.
Well, looks like this is now backfiring at me.
I'll test what happens if I revert to the old version, maybe the
problem back then was something else...

[linux-dvb] CA_CI_MODULE_READY not reset when CAM removed from AV7110 DVB card
I'm currently improving VDR's CAM handling, and while doing so
I came across what seems to be a bug in the AV7110 driver code.
If I do
int fd = open("/dev/dvb/adapter0/ca0", O_RDWR);
ca_slot_info_t sinfo;
sinfo.num = 0;
ioctl(fd, CA_GET_SLOT_INFO, &sinfo);
to check whether the CI adapter contains a CAM, the value of
sinfo.flags is 0 as long as no CAM is inserted. When I insert a CAM,
it first goes to 1 (CA_CI_MODULE_PRESENT) and then to 3
(CA_CI_MODULE_PRESENT | CA_CI_MODULE_READY). So far everything is ok.
However, when I remove the CAM from the slot, sinfo.flags still remains
set to 3. It never goes back to 0.
Is this a bug or "intended behavior"?

Sounds like the same problem I had. The card generates a +5V power supply for active antennas. If your antenna shorts the power, the card won't receive anything. There is a jumper on the card which you can remove to turn the power off. Klaus ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb

[linux-dvb] Improved rmmod.pl script
The rmmod.pl script that comes with the current driver source blindly tries to load all modules it can find. While this is good in case one has no idea which modules to load, there's no easy way of finding out exactly which modules need to be loaded to support just the installed hardware (unless I've missed it). The attached version of this script accepts additional parameters, which can be used to specify the "top level" driver modules to load, and starting from there it loads all other modules that the given ones depend on. For a system with full featured and budget DVB cards, the call might look like this: rmmod.pl load dvb-ttpci budget The modified script also makes sure that the explicitly mentioned modules are loaded in the given sequence, so that the sequence of devices can be defined (for instance making sure that the first device is a full featured card). This also works with 'reload', as in rmmod.pl reload dvb-ttpci budget So this could be the only line necessary in a 'runvdr' script, because it first unloads all given modules and the ones they depend on (if any are loaded) and then loads the given ones plus the ones they depend on. Without the additional parameters the behavior is as before. Maybe this is also useful to others. If so, perhaps it could be checked in to the Mercurial by somebody with write access.

The only thing that seems strange to me is that the first error is because struct snd_sg_buf isn't defined. In 2.6.12, this _is_ defined in the kernel file include/sound/memalloc.h, and bt87x.c _does_ include this file. It's no different than 2.6.18-rc4. So it should work under 2.6.12 (and 2.6.13 too I would assume), but doesn't. I'm not sure what is going on. Something to do with include searching maybe?

[linux-dvb] How to compile the firmware into the latest driver?
I've downloaded the latest driver source (v4l-dvb-79d6a1de784a) from the Mercurial repository, but somehow I have a problem with it. I want the AV7110 firmware to be compiled into the driver. But I don't seem to be able to make it do that. I tried editing the linux/drivers/media/dvb/ttpci/Kconfig file and changed the default value of DVB_AV7110_FIRMWARE_FILE to point to my firmware file's location, and also added 'default y' to DVB_AV7110 to have it activated. After that I did 'make' in the top level directory of the driver source, but it didn't compile the firmware into the av7110.o module. There wasn't even an av7110_firm.h file generated. Looking into the '.myconfig' file in the 'v4l' subdirectory I found CONFIG_DVB_AV7110_FIRMWARE := n which probably explains why it wasn't compiled into the driver. I sure must be doing something wrong here. What I want to do is to download the latest driver source, unpack it, maybe run some script that patches some files in order to have the firmware taken from my custom location, and have it compiled into the driver. All this should be done in batch mode, without me having to respond to any menus or stuff like that. Any idea how this can be achieved?

If it's not hard to do in userspace, why is it so hard in the driver? Why should every application implement this by itself? I'd say this should be done by the driver, and the applications shall exchange complete TPDU's with the driver. Or did I misunderstand this and you're talking about something completely different?

According to the DiSEqC "Application Information for Tuner-Receivers/IRDS", page 13, may setup should be correct. The relay is configured to react on DiSEqC "Option A/B", and according to the DiSEqC specs the values F0..F7 imply "Option A", while F8..FF imply "Option B". So with a sequence like [E0 10 38 F0] W100 [E0 10 38 F0] the first [E0 10 38 F0] goes to the relay, which switches to the first switch (Option A), then (after 100ms) the same sequence is repeated and reaches the switch. The switch then goes to satellite position A, polarization V, frequency Low. The dvb-kernel driver works fine now with hw_sections = 0 (see the other postings in this thread).

Andrew, you're the best! I've changed to hw_sections = 0 in the dvb-kernel driver and DiSEqC now works as reliably as with the DVB driver. I then switched the DVB driver to hw_sections = 1 in order to cross check, but the DVB driver still switches DiSEqC reliably, even with hw_sections = 1. Finally, I switched the dvb-kernel driver back to hw_sections = 1 and again DiSEqC didn't work reliably. So apparently the dvb-kernel driver doesn't handle DiSEqC reliably with hw_sections = 1, while in the DVB driver it works with both 0 and 1. I can, of course, use the dvb-kernel driver with hw_sections = 1 (as I always did with the DVB driver) and this solves my immediate problem. However, there must still be something else that influences things here, because in the old (DVB) driver the actual value of hw_sections didn't matter...

This change was done to avoid glitches in recordings on the primary device
in case the channel is switched.
Does it change anyting (DiSEqC wise) if you comment that line out?

Its the only thing I can see that might be different. The firmware that was originally on linuxtv.org for use with dvb-kernel 1.1.0 had version 0x261a, and thus was exactly the same as used in dv-kernel 1.0.1. So from what I can see the problem is definitely not in the firmware, because with the exact same firmware the DVB driver works fine here, but dvb-kernel does not. Since I am using a different hardware than my normal VDR machine for this, I have now explicitly tried the DVB driver on that hardware, and DiSEqC works just fine there with my setup S19.2E 11700 V 9750 [E0 10 38 F0] W100 [E0 10 38 F0] S19.2E 9 V 10600 [E0 10 38 F1] W100 [E0 10 38 F1] S19.2E 11700 H 9750 [E0 10 38 F2] W100 [E0 10 38 F2] S19.2E 9 H 10600 [E0 10 38 F3] W100 [E0 10 38 F3] Klaus -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.

Besides, even with the DiSEqC setup S19.2E 11700 V 9750 t v W15 [E0 10 38 F0] W15 A W15 t S19.2E 9 V 10600 t v W15 [E0 10 38 F1] W15 A W15 T S19.2E 11700 H 9750 t V W15 [E0 10 38 F2] W15 A W15 t S19.2E 9 H 10600 t V W15 [E0 10 38 F3] W15 A W15 T (which definitely explicitly waits 15ms before sending any DiSEqC sequence) it doesn't work (see my reply to Holger's mail).

Not much to my surprize this doesn't work, either. The multiswitch I use ignores any "analog" switching stuff as soon as it receives the first actual DiSEqC sequence. So doing the t-v-A-t dance doesn't make any sense. I also updated the driver to the latest CVS (2004-03-15, 17:31), compiled both driver and VDR newly, but there was no improvement. So all I can say is that I still believe DiSEqC handling is broken in the current dvb-kernel driver.

Ok, if it is defined behaviour that the driver does _not_ turn on LNB power when opening the frontend, that's fine with me - I have a workaround in VDR now. I just wasn't aware of this change, and apparently it has nothing to do with the actual problem of DiSEqC switching being unreliable with dvb-kernel.

But my DiSEqC equipment _does_ work fine with the DVB driver and sending plain hex codes (like [E0 10 38 F3]). The LNB power issue has been resolved by explicitly turning it on in VDR, so I would expect the DiSEqC equipment to work with dvb-kernel - but it doesn't (at least not reliably) Klaus -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.

Note that I _do_ turn on LNB power now when setting up the devices in VDR. The only thing is that I don't send the "old-style" tone, voltage and burst commands, but simply use plain DiSEqC codes like [E0 10 38 F0]. This works absolutley fine with the DVB driver, and I would expect it to still work in dvb-kernel. However, there it only works sometimes...

As of version 1.3.6 VDR explicitly turns on the LNB power at startup (which I believe the driver should do when the frontend is opened), but that didn't fix the actual DiSEqC problem (unreliable switching).

Well, then there must still be some bug that keeps DiSEqC from working in the dvb-kernel driver. I have changed VDR today so that it explicitly turns on LNB power at startup, but the DiSEqC switching is still totally unreliable. I'll give this another try next weekend...

The only important thing is to > maintain the delay times required by the spec, the diseqc.c example shows how > this can get implemented. With the DVB driver I am able to use a VDR DiSEqC setup like S19.2E 11700 V 9750 [E0 10 38 F0] W100 [E0 10 38 F0] S19.2E 9 V 10600 [E0 10 38 F1] W100 [E0 10 38 F1] S19.2E 11700 H 9750 [E0 10 38 F2] W100 [E0 10 38 F2] S19.2E 9 H 10600 [E0 10 38 F3] W100 [E0 10 38 F3] here the sequence [E0 10 38 F0] is sent, followed by a 100ms wait, and then [E0 10 38 F0] is repeated because the multiswitch is behind a DiSEqC relay. There's no need for explicit tone or voltage switching here. So I would say that activating the power supply to the LNB should be done automatically when the frontend is opened. As a workaround in VDR 1.3.6 I have added a call to ioctl(fd_frontend, FE_SET_VOLTAGE, SEC_VOLTAGE_13) when opening the device, but I think this shouldn't be necessary.

Sendeing DiSEqC codes in VDR is done via the ioctl(fd_frontend, FE_DISEQC_SEND_MASTER_CMD, &cmd)); call - is this no longer the way to go?

Well, I have a setup with two multiswitches behind a DiSEqC relay, and that workes just fine with the DVB driver.

Sorry, didn't mean to be offensive - it's just that I've finally spent the time this weekend to set up a machine where I can test the dvb-kernel driver, and it appeared to work fine, except for DiSEqC support. Since there have been quite a few guesses why this has been broken between the DVB and the dvb-kernel driver and AFAIK none of them fixed the problem, I thought this would have been the actual cause... > Not without removing the ability to be DiSEqC 2.x compliant and to support > anything else beside the standard single-switch, unidirectional DiSEqC 1.0 > setup. > > Those changes have been introduced about 2 years ago, proper rotor support and > support for cascaded DiSEqC devices would never have been possible without. > Bidirectional DiSEqC support neither. > > Can you please explain a little more in detail what exactly is your problem > and why it never showed up before? Up to now I have been (and still am) using the DVB driver 2003-11-08 and my cascaded DiSEqC setup works just fine with it. With the dvb-kernel driver (version as of friday afternoon) the DiSEqC signal is sometimes sent so that the relay and switch react correctly, and sometimes not. My DiSEqC tester sometimes displays weird combinations of LEDs (that don't make sense), and sometimes when switching polarizations there is no change in the tester's LEDs at all.

Following is the "switch frequency" of the LNB (slof), which is the transponder frequency up to which this entry shall be used; the first entry with an slof greater than the actual transponder frequency will be used. Typically there is only one slof per LNB, but the syntax allows any number of frequency ranges to be defined. Note that there should be a last entry with the value 9 for each satellite, which covers the upper frequency range.

I tried this, but there was no change at all.
Switching polarizations with DiSEqC still doesn't work reliably.

Yesterday I have set up a new machine with SuSE 8.2 (kernel 2.4.20) and a Siemens DVB-S rev 1.3 card. Driver is the dvb-kernel version from yesterday's CVS.

Sometimes the switching does work, sometimes not. There are even cases where some of the other LEDs on the tester light up, like "Reply OK", which, I believe, indicates that the DiSEqC sequence actually sent is broken in some way. I am using the exact same diseqc.conf with VDR 1.3.5 as I do on my other machine with the DVB driver on SuSE 7.3, kernel 2.4.10. When I switch to not using DiSEqC (just 14/18V, 22kHz) everything works just fine. So, in order to use the latest dvb-kernel driver in a DiSEqC environment, something needs to be fixed here.

[linux-dvb] dvb-kernel: old firmware
Ok, so I've set up a machine with SuSE 8.2, kernel 2.4.20, fetched the dvb-kernel driver from today's CVS and the firmware from http://www.linuxtv.org:81/download/dvb/dvb-ttpci-01.fw. Compiling the driver and VDR worked just fine, and it appears to run ok. Just one thing: apparently the firmware in vb-ttpci-01.fw is version 0x261a, while the latest firmware version as used with the DVB driver is 0x261b. Maybe somebody can fix this.

I was thinking about giving the new linux-dvb driver a try today, on a SuSE 8.2 system with kernel 2.4.20 - but from what I see here there's apparently so much confusion about this driver that I guess I'll rather not waste time on this...

But they are very widely used _now_, and will be as long as they physically live. I don't think that people are going to throw away their full featured cards just because some people say "they have no future"... I'd really like to see a new, full featured, DVB card come onto the market that does away with all the shortcomings of the TT design, has a better OSD and digital audio output. If such a new card would work with the LinuxDVB driver I'd by several of them in a heartbeat.

The recording format of VDR _is_ PES (or is it PS - sometimes I'm confused with these terms, so if in doubt, just look at an actual VDR recording), and that's what it sends to the output device. It won't use two different formats or go to TS as recording format. Klaus -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.

Does this mean convergence(?) will be producing a DVB-S/C/T PCI card that - can deliver the full TS - can do (PES-) MPEG decoding in hardware (the format VDR currently uses) - supports CAMs through the LL interface - has a fullscreen OSD with at least 256 colors - has a builtin AC3 output port - has A/V and RGB output (others?) - does not require any firmware (or at least no "closed source FW") - is _really_stable_ - did I forget anything?

Well, Holger, you keep repeating over and over that the av7110 driver is "broken" and that this is "ancient" hardware and how great "modern" hardware ist - but IMHO you totally neglect that the av7110 still is probably the most widely used hardware! People have invested real money into these full featured DVB cards and just don't want to throw them away. Plus, there just isn't any reasonable alternative And don't say "use a budget card and do replay over the graphics card" - the average user wants to insert *ONE* card into his PC and use that one for recording AND replay. Besides: replay over graphics card means MPEG decoding in software, which in turn requires more CPU power... Also: are there any budget cards already that have drivers that support CAMs? I have to admit that I don't know that. So, what about just fixing the av7110 driver?

I just meant that VDR 1.3 uses "thread ids" instead of "process ids", which is necessary with NPTL. There's no other special stuff for NPTL.

[linux-dvb] dvb_frontend_recover not working
I was looking into why the driver doesn't recover after a loss of signal (like when pulling the antenna cable for a few seconds) and found that apparently (at least with DVB-S) it starts a dvb_frontend_recover() sequence, but aquires a lock at a completely different frequency, which is some 16MHz off the original transponder. This is not surprising, because the fe->lnb_drift takes on values of up to +/-15462 or so, which lets it run into the next transponder at the same polarization as the current one. So no wonder there is no more picture then, because the PIDs may be totally different on different transponders. I therefore limited the range of fe->lnb_drift in dvb_frontend_recover() to some 8MHz, but then it didn't lock on to any transponder any more. This is what puzzles me, because the original transponder was perfectly locked on with fe->lnb_drift==0, and that value is the first one that gets tried in dvb_frontend_recover(). And since there can (due to the limitation to 8MHz) be no more other transponder it might lock on to by mistake, I don't understand why it doesn't lock on to the original transponder any more. It just loops through the original frequency +/-8MHz in 32 steps over and over again. Note that I did all these tests with the most recent CVS version of the DVB driver, but dvb_frontend.c appears to be quite the same (with respect to the dvb_frontend_recover() mechanism) as in the dvb-kernel driver. Does anybody have an idea why this doesn't work as expected? We should really get this to work in order to make an application automatically "come back" after the signal was lost, for instance due to bad weather.

How did you find out about this user-defined descriptor? Is there any documentation available about its format (and maybe other user-defined descriptors, too)?

I haven't used dvb-kernel yet and also have no 2.6 machine, but just wanted to drop in my 2 cents: IIRC there was a discussion a while ago about dvb-kernel being considerably slower in channel switching than the DVB driver (presumably because of different I2C handling). Is this still the case (or was it never the case)? If dvb-kernel switches channels slower than DVB, I guess this would be a "no-go" criteria for many people. As I said, just my 2ct, w/o personal experience with either dvb-kernel or kernel 2.6. Klaus -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.

I wouldn't call myself a "driver guru", but here's an observation I made: The Sat.1/Pro7 transponder uses the PIDs 97...107 for their PMT data. Maybe, when switching from a channel on that transponder to, say, RTL the PID 104, for instance, is still in use by the PMT section filter and thus can't be used for audio at that time. VDR does stop all section filtering before switching channels, so I would assume that from VDR's point of view the PIDs should all be available as necessary. Maybe there is a race condition in the driver that causes the already freed PIDs to still be "in use"?

Have you tried the VDR 1.3.0 developer version? This one includes automatic PID and CA setting. You also might want to set the Ca parameter to '0', as in TVSN:12478:h:S156.0E:27800:1081:1082:0:0:3008:0:0:0 VDR 1.3.0 will then automatically fill in any CA system ids automatically.
