[linux-dvb] dib0700 and analog broadcasting

[gothic nafik]

hi,

i have problems with my tv tuner. It is hybrid (analog receiver, digital
receiver, radio fm reciver) tv tuner with chipset dib7700. I had to hack
dib0700 module and update a line with my product id and vendor id
(because my hardware was not there). It is tv tuner in notebook Asus
M51SN.

Digital tv is maybe working, I do not know, becasue in my region is not
digital broadcasting yet. But I want to watch analog tv or listen to
radio. And I am not sure, but I need device /dev/video or /dev/video0
(/dev/radio is not created too) for watching analog broadcasting (module
dib0700 did not create any /dev/video, just /dev/dvb/*)? Am I right? 

 
Thanks for help

The driver currently does not support analog video.

I am working on adding analog video support to the dvb-usb framework,
but it is far from ready, and lowest on my priority list.  The good
news is that I made some very nice progress last month, but I wouldn't
expect any kind of release for months.

Side note:  I said something very similar to the above last year.  I
made a lot of good rpogress recently, but I wont have time to get back
to it until a few weeks from now.

You should consider your device a digital-only tv stick for now, under Linux.

Regards,

Mike

One more question - what about radio and remote control via lirc? Can i 
receive radio signal via antenna (for digital tv) i got in box with 
notebook? Is today's version of dib0700 module able to create /dev/radio?

The driver supports IR, but does not require LIRC, afaik -- try it
yourself and find out if your device is supported.

Radio is analog, thus, not supported by this driver.

FWIW:  Working on CX25843 analog support for the dib0700 based
Pinnnacle PCTV HD Pro was next on my list once I get the ATSC support
working.

Devin,

Lets sync up when you get to that point -- I have a good chunk of code
written that will add analog support to the dvb-usb framework as an
optional additional adapter type.

Hopefully I'll get more work done on it before then, but if not, this
is at least a good starting point.

The idea is to add support to the framework so that the sub-drivers
(such as dib0700, cxusb et al) can all use the common code.

CX25843 is already supported, just the dvb-usb framework currently
lacks a v4l2 interface.

Regards,

Mike

[Albert Comerma]

[-- Attachment #1.1: Type: text/plain, Size: 3540 bytes --]

I already discussed this dibcom + analog with Michael and Pattrick and I
ended with the conclusion that was better to wait a little for Michael (or
somebody) integrate the standard stuff with the dvb-usb api. Seeing there's
more people interested that what we thought initialy I just send the answer
from Pattrick which give good guides on the dibcom stuff. I'm not going to
start anything, as I said I think is better to wait a little.

Albert

Here's Pattrick answer for the interested (again thanks for your kind help);

Analog and DiBCom, *sigh*, it works, but it is a baby nobody really wants.
OK, let me tell you, what I had once in mind: The analog and DVB hardware
abstraction in the driver is signifacantly different. That's why it was
possible for me to create something like dvb-usb, but not so easy to have
something like v4l-usb, which abstracts the streaming and other common
things.
Mainly the frontend-architecture is it, which makes DVB more powerful that
v4l hardware abstraction. But OK.
If there would be a generic streaming mechanism which works similar to the
one in dvb-usb, I think it would be relatively easy to add analog-support
for dvb-usb or to add a analog-support to a dvb-usb-based device (function
pointer which is called each time a URB is returned instead of directly
passing it to the dvb-demuxer).
For the dib0700-driver you need some things to set up in order to receive
analog audio and video (see attached):
First you need to configure the streaming interface on the
dib0700-usb-bridge. This is done with a USB request from the host and
depends on the video format.
Then the streaming needs to be enabled in a different way then in DVB.
That's it. If I understand everything correctly, there are no special
settings for the cx2584x, but time will tell. Also it is important to know,
that the audio is coming in on endpoint3 and the video on endpoint2, which
might give some AV async.

Patrick.

hmmm, Devin, Patrick, let me be selfish a little bit, that's what I do
best most of the time, so you can beat me up for it.

Can the new i2c request code for the new firmware be done first?

Nico

Re: [linux-dvb] dib0700 and analog broadcasting

[Patrick Boettcher]

Nicolas,

1) The firmware alone should fix the i2c problems, even with the currently 
used requests.
2) The new requests are necessary to have the xc5000 running correctly, if 
I understand everything correctly. So yes, it will be done first - I 
think.

Yes, I am doing the i2c work before anything else (hopefully tonight).

Oh, so I can document+link the new file on the wiki, then.

And start using it too!

This is most excellent, better then understanding women and Emacs

...just to clarify -- the "good chunk of code" is still just v4l2 API
glue.  I didnt do _any_ of the streaming stuff yet.

videobuf can work with usb devices now, but I'm not sure that its the
best direction to take, within dvb-usb.

Like I said before -- what I have is worth keeping, but its extremely
far from complete.

When I get into it next (probably next month -- its busy here now)
then I will do my best to clean it up and post the work-in-progress to
a mercurial repository.

I repeat -- this will just be for the sake of collaboration.  I don't
think this will be ready for users for a good long time :-/

Chances are that I've done my testing a bit too late in the night
considering the week I've had.

I've reverted to 1.10 and will redo the 1.20 from scratch tomorrow.

Off to bed now.

Will do.  I'm going back and forth now with Patrick to get his new
firmware and i2c interface integrated which will hopefully cause my
xc5000 to start working.

Yeah, I made that list more than ten years ago.  I should probably
update it since I'm now quite proficient in the Emacs buffer routines
(although my understanding of women has not progressed as far).

I started working on the code tonight and fed Patrick a bunch of
additional questions about the new API.  If I'm lucky I will get it
locked down this weekend.

I've tried again, fully awake. With full power downs, soft link or full
rename, etc...

Same thing. Self-reboot, no device, no message.

I downloaded the firmware again, same thing.

The md5sum I have is the following for the firmware file:
f42f86e2971fd994003186a055813237  dvb-usb-dib0700-1.20.fw

Reverting to 1.10 fw makes it work again.

dmesg, lspci, lsusb, lsmod available here, more can be provided on
demand:

In /etc/modprobe.d/options, I have:

# Load DVB-T before DVB-S
install cx88-dvb /sbin/modprobe dvb-usb-dib0700; /sbin/modprobe
--ignore-install cx88-dvb

# Hauppauge WinTV NOVA-T-500
options dvb-usb-dib0700 force_lna_activation=1

Interesting.  I installed the firmware, and although it hasn't helped
my particular issue (and it's behaving identically to 1.10), it hasn't
crashed my environment.  On the other hand, my failures occur fairly
early in the initialization so the problem may be further into startup
than I have gotten with my device.  I am running 8.04 with the latest
kernel and v4l-dvb code.

Does it happen right after you plug the device in, or does it not
occur until you start a video application?

If it occurs immediately on connect, perhaps you could jump out of X11
to the console before plugging it in, to see if there is any panic
output prior to the reboot.

Also, I can't think of why this would happen, but could you send the
md5sum of your firmware file so we can make sure it wasn't corrupted?

Difficult to say.

The Nova-T 500 is a PCI card. It has a Via usb controller and the USB
dib0700 behing on the card.

As for the application, I do not think I have to enter X. I can check,
though.

I have my MythTV setup so that it doesn't grab the cards for good from
the get go. It will only get to them when it needs to record.

As it is a PCI card, that will be difficult.

I have though of that, hence the new download and the already provided
md5sum:

Sure, it happens when X starts. But it could also be bad timing. The
MythTV backend, the app that really uses the DVB stuff, starts right
before X.


I have asked for debug info from the dib0700 module.

Aug 22 18:05:23 favia kernel: [   33.238864] dib0700: loaded with support for 7 different device-types
Aug 22 18:05:23 favia kernel: [   33.239009] FW GET_VERSION length: -32
Aug 22 18:05:23 favia kernel: [   33.239011] cold: 1
Aug 22 18:05:23 favia kernel: [   33.239012] dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in cold state, will try to load a firmware

And then nothing with 1.20 fw.

What is interesting, is that at each self-reboot, that are warm reboots,
the card is in cold state and needs a firmware. So can I conclude that
it never got loaded? Or that the self reboot is a cold reboot?


I have tried to boot without a firmware file, and it goes all the way to
MythTV without reboot.

hmmm...

OK.

It works now.

A lot of noise about not much, and that makes me wonder how much of an
idiot I am...

I did a 

sudo find /lib/firmware/2.6.24-1* -name "dvb-usb-dib07*.fw" -exec rm {}
\;

It did remove all the 1.10 firware files provided by the Ubuntu
packaging.

I made sure that I had the 1.20 fw with the 1.10 name in /lib/firmware,
and all is working.

Apparently the driver/kernel was confused about which file to pick-up.

Nico
