Tuning failed on 8PSK channelsearch using x86_64 as client and dreambox as server #2

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Search channels on Thor 0.8W on dreambox
2. Search channels on Thor 0.8W on PC
3. look at the differences.

I think this might be something with vtunerc kernel module as dreambox finds 
all HD channels and PC doesnt find any channels on 8PSK S2.

(It finds NRK HD etc. but that is on 8PSK)

I can't reproduce this at the moment (as the kernel module is borken), I'll 
come back as soon as the kernel module is working.

I've only access to astra 19.2E. It'd be cool if you find not working/scanning 
channels on this satellite.

The same problem happened on sirius 4.8E with tuning failed on S2 channels.

As the dish is at my parents house i cannot promise that I will be able to but 
i will try scan Astra Asap.

Just tried the patch and no differences, tuning failed on DVB-s2 but finds 
channels on dvb-s

I really thing its the driver that has the problem as it does work on my 
dreambox standing 5cm next to my x86_64 pc.

I dont know if its something important but when I used to own a kathrein I had 
to activate highsr to be able to scan HD channels.

Hi,

I've yesterday tried all 3 parts (vtunerc.x86_64, vtunerc.ko and as daemon 
vtunerd.arm over stv0900+stv6110) compiled from fresh downloaded sources with 
patch to Makefile for x86_64 applied. I was able to scan all DVB-S2 
transponders from 0.8W except those transmitted on beam K1 Nordic due to lack 
of signal.

On positions 9.0E, 19.2E and 23.5E I didn't find any problem, I was able to 
scan all DVB-S2 transponders from these positions I've randomly selected (lack 
of time).

Please could you be more specific over which hw you are used the daemon? Maybe 
this info could help Honza to find and locate the problem.

Ales

P.S.: Please attach also info about driver and DVB-API versions used in server, 
thanks.

A.

Hi again,

Hardware for the daemon is just a dreambox 800.

Im living in sweden so K1 should not fail for me (1m dish) and it works using 
(dreambox <-> dreambox but not pc <-> dreambox)

Could you try (if you got time) this transponder? (its T2)
11785,
8PSK
SR 30000
FEC 3/4

You should then find these channels:

Canal + Extra HD/3D     
MTV Live HD     
Nat Geo Wild HD Europe
ESPN America UK
National Geographic Channel HD Europe

The client has Ubuntu (yavdr) with latest version of both client and daemon. 
Was same problem with my gentoo box.

dvb-api version: As its dreambox so I guess its dvb-api 5x.

p.s tried dreambox <-> dreambox now again and it finds 0.8 HD channels (canal 
digital) and 4.8E (viasat) channels which is strange :S

Copied to much so had to delete comment and post it again.

On server is DVB-API 5.3. My PC is amd64, Gentoo, kernel 2.6.35.

But if you are using DM800 as server are you using binary for it compiled or 
downloaded? As I remember there were some changes within last months.

Thank you, I see some light on this :)

I modified the code a bit and I get dvb-api Version 3 when I compile myself but 
dvb-api version 5 when downloading the binary.

What am I missing?

Original comment by kriss...@gmail.com on 12 Aug 2011 at 8:29

GoogleCodeExporter commented 9 years ago 
The dvb-api used, is controlled by the kernel headers, included. I'd guess that 
either something is wrong with your headers or the include path is pointing to 
the wrong directory.

I recommend to check whether you have multiple directories containing 
"include/linux/dvb/version.h" (using eg. locate include/linux/dvb/version.h)

The correct version.h will have the following definition:
#define DVB_API_VERSION 5

Thanks, removed Ubuntu and reinstalling gentoo again, so I hope it will work 
out as the problem has to be at the client as dm to dm works, so I hope it will 
get sorted.

I think I have found the bug: vtunerc.ko is using SET_FRONTEND cmd even for S2 
channels (then S2 parameters are encoded inside). It works fine if server is 
DVB API compliant box (linux PC), because vtuner-dvb-3.c is doing the job and 
translate encoded S2 parameters back correctly. What is not case for 
vtuner-dmm-3.c code a so it not works on dreamboxes (when dreambox acts as 
server, so vtunerd.mipsel is involved).

When I get installed mipsel crosstool I will check it.

Some progress :) but still doesnt work all the way.

during transponder scan
(time: 01:05) (time: 01:08) signal ok:
        S2 f = 12015 kHz H SR = 30000  3/4 0,35  8PSK

Now during channel-search

tune to: S2 f = 12015 kHz H SR = 30000  3/4 0,25  8PSK
(time: 05:06) ----------no signal----------
tune to: S2 f = 12015 kHz H SR = 30000  3/4 0,25  8PSK  (no signal)
(time: 05:08) ----------no signal----------

At least no "Tuning failed" :)

Interesting. Why it gets "not signal" if tuning is ok?

OK, I will go futher with my investigations :)

Why do you have ROLLOFF value different in tp scan (0.35 what is correct) and 
in channel search (0.25 what is wrong!)

Actually dont know, what I did is use this command line
w_scan -f s -s S0W8 -D 0c

Original comment by kriss...@gmail.com on 30 Aug 2011 at 11:34

GoogleCodeExporter commented 9 years ago 
Well, my today's experiments with w_scan have few thoughts:

1, latest version has much better results:
 I have d/l and installed latest one: w_scan version 20110702 (compiled for DVB API 5.1)

2, adding higher timing helps a bit too: -F -t 3
3, i can confirm that 8PSK scanning works:

tune to: S2 f = 11817 kHz V SR = 27500  3/4 0,35  8PSK 
(time: 40:22)   service = BBC Entertainment (SatelliteBG)
    service = Boomerang (SatelliteBG)
    service = Da Vinci (SatelliteBG)
    service = FLN (SatelliteBG)
    service = Travel Channel (SatelliteBG)
    service = 1 TVRUS (SatelliteBG)
    service = Planeta HD (SatelliteBG)
    service = Opentech (ITV Partner)

Of course there can be some issue when using w_scan (like it not waits enough 
for getting PAT/SDT/NIT tables or it parse some tables wrongly). Unfortunatelly 
I don't have any usb or pci dvb-s2 card here to check if same w_scan works 
better when used locally.
