Hello, help!
I can "dvbscan" and "tzap", and gets indication of a good signal. BUT,
I cant view the video!
(from the dvb device)
Also "dvbdate" command works (that returns time and date from the air, I
presume). But not a command as "dvbsnoop" (that need
"/dev/dvb/adapter0/dvr").
A sample: ( Its step by step of your guide:
http://www.linuxtv.org/wiki/index.php/Testing_your_DVB_device )
In one console I run: /.tzap# tzap -r -c channels.conf "TV4 Öresund" (
and are getting lines as:
status 1f | signal c3c3 | snr ffff | ber 0000004a | unc 00000000 |
FE_HAS_LOCK
status 1f | signal c3c3 | snr ffff | ber 0000004e | unc 00000000 |
FE_HAS_LOCK
...
AND in another console:
mplayer -v /dev/dvb/adapter0/dvr0
(thats basically halts without any further information)
ALSO if I type: "cat /dev/dvb/adapter0/dvr0 > afile.txt"
(But then again, "afile.txt" remains empty)
Conclusion, /dev/dvb/adapter0/dvr0 never returns anything. This
"/dev/dvb/adapter0/dvr" isnt proper. Must be a Linux-kernel/module
problem..
Here are some further info of whats on my system:
* Media Card: "Asus P7131 Hybrid"
(This very same Media-card worked on an older machine, an old Pentium,
that I now abandoned. Maybe I used the line "card=112 i2c_scan=1
tunar=54 gpio_tracking=1" when loading "saa7134" kernel-module, for
this. By a gento wiki-tips (http://gentoo-wiki.com/HARDWARE_saa7134). I
tested this line on this AMD64 machine also, but didnt make any
difference..
* Linux-kernel, "2.6.22-3-amd64" (The only kernel I see in my
Debian-testing apt list, cant use any other kernel, strange also..)
* The system, Its some dual AMD64, mother-board Asus "M2A-VM HDMI" (a
card with most stuff built-in, as sound graphics.. etc) A common card
(for building computers aimed toward media, as this is).
* Mplayer (for what its matter, gnu "cat" dint work ether, so it doesnt
matter). I have compiled Mplayer myself, with everything possible
included. Also, I have tested Debians deb-package called the same name,
but without success (or difference).
Maybe I could include the returns of the old and new "lsmod", but the
only difference there regarding this is, that I now dont use Alsa (sound
system). Now I use the default outof-the-box-configurations (a fresh
installation, this my system is, now). So I dont include what "lsmod"
returns, in this email (because then I can continue with "lspci" "dmsg",
and all possible and impossible sniff logs.. I dont know what may be
relevant info, to solve this.
Any comments and Ideers are welcome! !
thx.
I just signed up for this mailing-list ( I hope this is the right
forum.. thanx again. Also I hope the solution is simple.

Not so fast! If the channel is encrypted, this is precisely what you
will observe ... though, because this is over-the-air that we're talking
about, this seems less likely to be the case (but you will have to
confirm nonetheless).
I'm more inclined to think that this is related to an issue with stream
identifiers. Is Sweden using MP4 now?
Some further questions, what drivers are you using (distro or recent
LinuxTV)?
What dvb-apps ... Christophe had updated the dvb-apps not to long ago
with some changes in regards to MP4 streams (can't remember the exact
nature, but perhaps you should grab a new copy from LinuxTV and try with
those).

The channel isn't encrypted.
(I have tested with many public chanels, that I know isnt encrypted.
Cant get any video out)
Im Debian-tesing user, and this is a freshly installed system. On a amd64..
(as I mentioned, in previous email)
Turns out "/dev/dvb/adapter0/dvr0" isnt the only device that doesnt work.
(framebuffer didnt work ether, "/dev/fd0" are missing totaly, regardless
of bootloader vga=791 options or so).
I removed (by now mistake) older kernels when I distupgraded, cant
nerrow down the error search, by testing other linux-kernels.
(since I only have one, the 2.6.22-3-amd64)
And snapshot.debian.net didnt record any older.. Only option left, to
start compilling by myslef.
(but to rough)
Probably testing another distro (Ubunto) next week.

Whatever frontend I test, it will not work.
The device, never stream anything.
I can tune, but not view the video.
(thats it)

I haven't followed this thread from the beginning, but did you say what
kind of DVB hardware you have?
I know the Nova-TD stick is a bit picky. Too strong a signal will cause
the behavior you describe on this device. On my Nova-TD, using a good
antenna will yield no data stream (but a 100% signal), whereas if I use
the little mobile antenna that came with the stick, I get a stream but
mpeg artefacts in the picture (due to low signal).
I would try attenuating the signal (or removing amplifiers) or a
different antenna. I would also give it a shot (since you're using
mplayer to test) to use mplayer to control the whole scenario (tune,
stream-on, demux, decode and display). Try the following command:
mplayer dvb://1@TV6
Using the TV6 channel will avoid any obstacles by the channel name
containing extended-ascii (Ö) and space ... TV6 should be an unencrypted
channel and on the same MUX as TV4, even in the Öresund region ;)

Hello Jonas Andren.
(Kom inte o säg att Anden är dansk)
The Harware I have, I have said. Its the media-card, is this:
http://www.linuxtv.org/wiki/index.php/Asus_My_Cinema-P7131_Hybrid
(running on a amd64, mother-board m2a-vm.. Inköpt på Kjell&Co byggsats
för 2 veckor sedan...
I also said that the same Media-card did function (somewhat) on my old
computer (a PII330MHz, though with terrible video result). And it works
in Windows XP. So, the Media-card function.
I downloaded&installed linuxtv-dvb-apps-1.1.1.tar.bz2
<http://www.linuxtv.org/downloads/linuxtv-dvb-apps-1.1.1.tar.bz2>
(and all so called utils: "dvbdate" "dvbtrafick" "scan" and "zap"
worked. BUT, nothing under the test)

you should prefer dvb-apps from mercurial, but that is not so important.
First of all I would like to see relevant "dmesg" stuff for the card
and tuner to see if it is still likely the same card, auto detected and
eeprom content unchanged and all chips alive. If you enable i2c_scan=1
you look first for the devices found.
Also we never saw, if your firmware upload is successful and if you use
preferably revision 29 with such a card with Low Noise Amplifier.
If not, download it from LifeView with the script in /Documentation/dvb
and do a cold boot. (recent stuff is in a v4l-dvb mercurial snapshot)
Antenna input for DVB-T is FM/RF input.
Can you point to the initial tuning file you are using or to what you
believe is a valid channels.conf file for you?
It is always worth a try to set all to AUTO in the initial tuning file,
except frequency to tune and bandwidth and then use "scan" to create a
channels.conf.
If still not, we install the recent v4l-dvb, remove all old modules and
might try to debug from there.
Cheers,
Hermann

Thanx! Now it works!!
Watching some Danish (Dansk) channel, about Napoleon.
Thanx again, for mocking me up.. It was the channel.conf, that was wrong
The channel.conf -file that I used before, was 6 month old and from my
previous computer.
(Now "dvbscan" doesn't detect anything on that bandwidth. And that "TV6"
was on that..
If I run dvdscan against the closest mayor city (Malmö in my case, here
in south Sweden), it only tunedin encrypted channels. BUT, against all
of Denmark (file "dk-All") I get a some..
Its strange though.. I CAN SEE "TV6" unencrypted, but in Windows XP. But
there with A program called "PowerCinema" is used (in XP OS).
(tuning is a fuzz there also, I believe "PowerCinema" download channels
and guides and what, from the internet. It would maybe be a point to
retrieve its (channel) configure file. I have looked, but found none.
Another question now, how is all these "initial-tuning-data" created??

There is a deb-package called "mercurial".

I used the linux-kernels-source. in its documents for this. Downloaded
the firmware..
(I include dmesg output in the end of this email, anyway. The revision
is 20, and not a LifeView fabrication..

Yes, now my system is relatively fresh, again (I dont load any

I also tried to compile the kernel (there was this option there
VIDEO_ADV_DEBUG). But unfortunately I cut away so other stuff, soo the
new kernel got panic at bootup. Another story..
It was the "channel.conf" that was wrong.. Thx again!
(what a fuzz)

Either the broadcasters provide them or people try as good they can.
Since different channel decoders vary in the tolerance for having
something wrong there, and also broadcasters often change something,
with the tda10046 better try as recommended.

There are a lot of Swedish channels.conf in dvb-apps now.
In "kaffeine" you just select the transmitters in the dvb configuration.
You also can combine multiple transmitters or try with
"w_scan".

Thanks. It is the known card with LNA.
According to Asus, Philips/NXP firmware prior to revision 26 had
problems with missing channels.

All the older P7131 Dual cards have a firmware eeprom and only the
oldest revision needed an upgrade. Since you have no firmware on eeprom
"./get_dvb_firmware tda10046lifeview".

With kernel devel environment installed v4l-dvb from the mercurial
master repository is easy to use. (currently down to 2.6.19, sysfs
compat for 2.6.18 is broken, >= 2.6.20 works for sure)

Sorry, but for example with "kaffeine" and "w_scan" you should be fine.
