vtunerd in VU+ Duo receiver does not transmit audio and video

[GoogleCodeExporter]

What steps will reproduce the problem?
vtunerd in VU+ Duo receiver does not transmit audio and video to vtunerc in 
ubuntu (10 or 11)

What is the expected output? What do you see instead?
To get audio and video on my ubuntu by using VU+ Duo tuner.

What version of the product are you using? On what operating system?
I tried binaries given here in September and October, I also compiled with 
today's source codes and used vtunerd.mipsel (I had already mipsel compile 
enviroment on my ubuntu) and vtunerc.i686. All gave the same result.

Please provide any additional information below.
I can see signal amount and EPG data on client perfectly but no audio or video 
is transmitted. 

Just as a not, T can easily have audio and video with my external usb dvbs2 
card.

I think there should be some code modification needed for VU driver.

I would be more than happy to  test to help you and, provide  any logs needed.

Best regards...

I'm sure that vtunerc is mounted on /dev/dvb/adaptor0/frontend0 since I can see 
audio picture with szap + mplayer combination. It's just perfect for freeview 
channels. Could't tried scrambled channels since I could not have audio/picture 
on my OpenPLi. Did you have any chance to test XSHM ?

BTW, can I learn in PLi forum nick :)

Do you:  git pull

and recompile the OpenpliPC osd branch because it is often updated, and first 
version doesn't support OpenGL just XSHM but the latest version now support 
also OpenGL.

Yes, I created openpli OSD branch from scratch last night. I both tried OpenGL 
and XSHM. OpenGL is not still working on VM, it's killed immediately This is 
completely a VM related issue. But XSHM works, I got OSD, I saw a logical 
signal value on the skin without audio or picture. Of course I can install and 
use directly to my PC instead of VM, but this is not the target. I want to 
prepare easily shareble VM images with working and ready to use OpenPLi 
installed for people witout any linux and compile knowledge. I'm sure there is 
something very small is overlooked since I got audio/picture with usb tuner 
with XSHM? BTW, audio/video is not the only problem, as I said before, channel 
scanning also cannot find no channels. I did nothing special:

1- compiled openPli from scracth.
2- started vtunerd and vtunerd.
3- I saw audio video with szap+mplayer
4- restarted vtunerd and vtunerd.
5- Copied my settings from VU+ to OpenPli.
6- Changed tuner setting to VTuner.
7- Changed xine.conf as XSHM
8- Started OpenPli

Is there any missing step or setting ?

Hi,

I think that the goal here is not to troubleshoot your OpenpliPC installation.
Please post your questions on Openpli forum where people can help you.

For me issue #13 on vtuner is now solved since I didn't change anything in the 
source code, I just compile properly the vtunerc and vtunerd towards VU+ 
include files for you.

Mebepi.

Yes you're right. At this point I'll try other dvb applications to be sure 
about the vtuner since to verify channel scan and channel change. I just only 
one channel in my szap config file (since manually adding channels to this file 
is a bit difficult), then I'll try to make openpliPC work.

These are my last question, could you please kindly answer them as a final note 
:

1- BTW, you changed no code? I previously tested vtunerd.mipsel files given in 
this site, and you can find one in the above messages given by Honza. None of 
them worked with szap. So I assume only gcc that you used made the difference 
in my szap+mplayer tests? Right ? Is this the same for your XTrend ? 

2- I think you used vtuner-dmm-3, not vtuner-dvb-3?  So you did't changed make 
config ?

3- Should I do anything special to compile vtunerc for DVB API 5? I'm using 
ubuntu 11.10 and I assume that DVB API 5 exist on ubuntu 11.10. Isn't the one 
that Honza provides the same ?

Thank you very much for all you helps and precious efforts !!!

Hi,

1-

What I did is:
- Create a full Openpli environment for Vuplus on my build PC.
- I have the crosscompiler installed on my build PC.
- I create a full new bunch of file to build vtunerc/vtunerd based on mipsel 
one.

To do so I duplicate the ./build/mipsel into ./build/vuplus

Edit file:  ./build/vuplus/Makefile and change:

CFLAGS=-fpic -DHAVE_DVB_API_VERSION=5 -DHAVE_DREAMBOX_HARDWARE 
$(INCLUDE-$(ARCH)) $(INCLUDE2-$(ARCH)) $(DBGFLAGS)

Edit file: Make.config

# define the CC for target vuplus
CC-vuplus=/home/mebepi/vuplus/mipsel-unknown-linux-gnu/bin/mipsel-unknown-linux-
gnu-gcc
CXX-vuplus=/home/mebepi/vuplus/mipsel-unknown-linux-gnu/bin/mipsel-unknown-linux
-gnu-g++
INCLUDE2-vuplus=-I/home/mebepi/vuplus/build-vuduo/tmp/sysroots/vuduo-oe-linux/ke
rnel/include
INCLUDE-vuplus=-I/home/mebepi/vuplus/build-vuduo/tmp/sysroots/vuduo-oe-linux/ker
nel/arch/mips/include

The main point here is that I pickup the kernel include and arch/mips include 
file form the folder where I compile an openpli image for Vuplus (I choose a 
vuduo image).
This is the goal of INCLUDE and INCLUDE2 parameters.

After having compile towards those include file everything is working fine, so 
yes I compile with vtuner-dmm-3 (answer to question 2), nothing is changed 
compared to mipsel standard compilatione except the include files.

I do the same operation for xtrend and compared both compiled vtunerc and 
vtunerd md5sum and they are the same, so the headers are the same both for VU+ 
Duo and Xtrend ET-9x00.  I should check with VU+ Ultimo to see if the result is 
the same.
But since I don't own VU+ hardware this is not really usefull for me.

3- On Unbuntu you need to change the include file location to: 

Follow the tuto:  http://wiki.nessiedvb.org/wiki/doku.php?id=install_vtunerc

But replace the KDIR command mentioned in the tuto with:

make KDIR=/usr/src/linux-headers-`uname -r`

I already provide to Honza all the informations to successfully build a version 
for VU+ and Xtrend.

Mebepi

P.S.: if you don't know how to build a full openpli image please check this:
http://users.telenet.be/spstefansp/openpliubuntu.html

But be careful you need to use Makefile-2.1 and not Makefile-2.0 like in the 
explanations.
The hardest part is to find all the required packages to successfully build the 
image, since some mirrors are temporarily down or sometimes no longer available.

Thank you very much again for the complete answer ! I have already openpli 
compile environment, it seems as I just need to modify make and make config 
files as you suggested. I'll try to compile vtuner this evening.

Oh, few days I'm out and so nice progress. Good job Mebepi!

In day or two I should be back and then we can commit all necessary changes for 
build system to get working binaries for VU+/ET boxes.

@Mebepi

I compiled vtunerd for VU this evening, with the suggested Make/ Make Config 
modifications. My compiled binaries gives the same with the ones that you 
attached above. Here are the results:

1- szap+mplayer gives audio + video with a manually created channels.conf.
2- w_scan finds no channel, so I could not create a channels.conf.  It locks to 
the frequencie,s but cannot find any channel.
3- I get No audio/video on PliPC with imported settings. EPG is OK. Signal is 
OK. BER always shows numbers like 31 strangely.
4- PliPC cannot find any channels in channel scans. It locks to the 
frequencies, but cannot find any channel.
5- Finally scan with the Mythtv cannot find any channels in channel scans. It 
locks to the frequencies, but cannot find any channel.

@Honza,
You had suggested to me to use szap as the simplest test tool. What are the 
differences of other DVB apps when compared to szap? Do you have any 
explanation that my tests 2,3,4,5 fail while only 1 succeeds? Any suggestion 
for the further test cases to prove vtunerd is working with no problem or not.

As I said before, I'm using a Virtual Machine (ubuntu 11.10) on my Windows 7. 
Do you think this is cauesed by a VM usage? May be a second VU+ user should 
check the results ??

Regards...

Still no progress here :( I think there is something wrong for vu+ here which 
is not PLi specific.

I'm found following the error in PLiPC logs : "DMX_SET_SOURCE failed! - Invalid 
argument"

I included problematic part raising the error when tunning to a channel below, 
you can also find full logs attached.

Hey guys, first of all: what an awesome project. I'd just love to have 
tvheadend use my dreambox as a dvb tuner!

It seems like my setup is almost working, but I get the "no scan results" 
issue, apparently.

I have a: dm800se running OpenPLi that runs vtunerd.mipsel (20120104-r2) +
xbmc running on an arch linux machine (x64) running vtunerc.ko + vtunerc.x86_64 
which i compiled myself using the kernel 3.3 quick-patch found in issue 18.

Communication seems ok, i have tried "vtunerc -f s" and "vtunerc -f s2" (others 
(-f S or -f S2) do not connect successfully, as my tuner type = 9)

So the problem at this time is: i cannot scan for any channels (tried using 
w_scan, passing -D1u, -D2u, ... for diseqc switching, don't know it this is 
supported?). 

I tried manually adding channels to channels.conf and tuning with szap, but 
this does not seem to LOCK... (will try this again)

btw: is there a way to convert Enigma's channels to a channels.conf ?

Also, if there's know issues causing this behavior, on which I could help? I am 
an embedded C programmer, so I might be able to help a little.

Ok, I just read the line "Original Dreambox API is supported, but only up to 
August's 2011 DVB drivers!". I suppose this explains my troubles. I someone 
could point me out where I should look for improvements, to get it work on the 
new Dreambox API? Is there any documentation about the dreambox-API?
Should I look in the vtunerd-part, in vtuner-dmm-3 ?
I know very little about linux-dvb, so I'll have to do some research first.

best regards

Maxime, If you can test against some older kernel (non 3.3), please do it. As 
you could notice, I did 3.3 kernel patch blindly, so it is more then possible 
it consists of some bugs and this is a reason why it is not working for you.

jpetrous, everyone,

I have tried using a 3.0.x kernel, and scanning works now. (so using a recent 
OpenPLi image on my dm800se. I still have to check which driver version this 
image is using, exactly)
I will look into the new 3.3.x kernel dvb interface, and hopefully come up with 
a fix.

Best regards

I have also a lot of problems with getting vtunerd on my STB.

I'm using the stv090x driver. With the szap utility I got a lock but no tsdata. 
Now I'm trying the openpliPC project.

On some channels in e2 I see a PID list and on a lot of channels I see nothing. 
The ioctl(hw->demux_fd[j], DMX_SET_PES_FILTER, &flt); is failing also with 
"invalid argument". If I set the PID hardcoded to 0 the ioctl succeeds.

The attached log shows what's going wrong. The DEMUX FAILED logging is custom 
added.
