There are 3 Options availabe:
1. Software PID Filter (default on PCs)

/opt/bin/mediaclient -P off -d /dev/dvb/adapter1/frontend0

2. Hardware PID Filter (default on eg. dreambox and other boxes)

/opt/bin/mediaclient -P on -d /dev/dvb/adapter1/frontend0

3. Passthrough, ignore all filters

/opt/bin/mediaclient -P passthrough -d /dev/dvb/adapter1/frontend0

Aside of that you can always read what is passed to the settopbox by running

/opt/bin/mediaclient --cat /dev/dvb/adapter1/dvr0 > /media/hdd/stream.ts

Oops. How your device remember chosen options? config file/flash cell? Or It option automatic ajusted by the driver's intellect?
Before I am start using this stick with the VU+ STB, I performed a some tests on PC (with the set of different softwares). May be it is the point of problems? Some PC software enables HW/SW PID filtering and this config is deep stored into the device ?

[Sundtek]

You can read through the driver configuration file

http://wiki.sundtek.de/index.php/TreiberKonfiguration

the commands are instant options, as soon as you run them they will be active immediately

BIG Thanks for the manpage! I am completely missed this page (installation/configuration steps I've got from forum messages only).

I'll checkup the my configs by this evening.

[StAlex]

I'll checkup the my configs by this evening.

Something strange in that kingdom.
first: by default I am do not found the /etc/sundtek.conf file.
When I create it (even if it contains only commented lines), the tuner fails to start.
The example file I've take from wiki page.
second: if I pass the command
 /opt/bin/mediaclient --tsscan /dev/dvb/adapter1/dvr0
it does nothing. Just freezes. It unfreezes by Ctrl+C

If I pass one of that command:
/opt/bin/mediaclient -P off -d /dev/dvb/adapter1/frontend0
or
/opt/bin/mediaclient -P passthrough -d /dev/dvb/adapter1/frontend0
no changes at all:
--tsscan - still freezes;
- no success on encrypted channels;
- no success on firmware update

It is I am doing something wrong ?

PS.
I am check the -e output. It contains next:

The driver is started with the --no-nodes option that's why it doesn't work.


however you can try to use following mediaclient version until the next driver version will be avialable:

http://sundtek.de/support/mediaclient

This version will support the --no-nodes option of the driver (that means that the node itself is not existent in /dev/dvb)

Edit:
official driver is udpated for that to support drivers which are started with --no-nodes

[StAlex]

Okay, I catch the new driver, and --tsscan is work for now. Thank you very much.
But, I want return to the on-topic problem.
I try to run once this command at this morning, and see the output starts with a lot of fake (zeroes) CAID's. Two or three dozen. I cant attach a log at this moment, but I can do this at this evening.
May be this is the point of unrecognized encryption by the driver of Marusys.
But anyway, at this evening I'll do some more tests with the mediaclient.

The last question: --no-nodes - it can be overridden to force nodes creation ? It can be useful to TS exploration with the dvbsnoop utility.
Or there are exists an another way to work with dvbsnoop (to perform comparing between different TS's from different tuners)?

[Sundtek]

Well you can check back with Marusys.

You can check it on a regular PC or start the driver manually on the settopbox.
The devicenodes are not created due bugs in some Enigma2 versions.

Shut down enigma2, and run /opt/bin/mediaclient --shutdown; /opt/bin/mediaclient --start


Before running dvbsnoop etc. run export LD_PRELOAD=/opt/lib/libmediaclient.so

[StAlex]

Before running dvbsnoop etc. run export LD_PRELOAD=/opt/lib/libmediaclient.so

I am not reach the success with the dvbsnoop. Even I run command described in quotation.
It is required the devicenode, or I don't know how I can run dvbsnoop on the DVB-C tuner. Starting dvbsnoop without specifying the device - fails. With the targeting on "virtual" node - fails too

Output for mediaclient --tsscan - is (with "cuts"): it starts with a lot of (~80 times) messages like

when I wrote the morning's message - I have been mistake by myself, because not paid enough of time.
What is the leading "stream" with the messages about "CAID" ? Is this normal for DVB ?
How can I understand a PID where the EMM/ECM transmission present ? It sould be a single PID for all channels. Do I am right?
And two comments on output of --tsscan command
#1 The first service - is not encrypted. It can be watched on totally FTA devices. And STB show this channel not marked as encrypted.
#2 The names of the services transmitted in cyrillic. Due to it correct displayed on STB, I think they are transmitted in UTF-8

The described quotation of --tsscan commnd taken  with the "-P off" option.

PS.
I would like you not tired?

[Sundtek]

capture the TS stream to hard disk, dvbsnoop is not fast enough to do realtime analysis.

/opt/bin/mediaclient --cat /dev/dvb/adapter1/dvr0 > /media/hdd/test.ts


CAT/CA system is just printed whenever such packet comes in.

Service name is probably not printed because of the russian character set on the console (only ASCII is printed, it's just for informational purpose on the console)

[StAlex]

interesting observation.

On the different channels, stick chooses different pid-space to HW filtering.
What is the algorhythm ?
For example, on the one cable-channel(I mean the frequency-holder; like "transponder" on DVB-S) PID-list is

Code: [Auswählen]

on the second (where the all channels is encrypted) is the

And another observation.
When I try to remove some(even the one) PID from the list (via pass the "-x NNNN" command), STB starts to show a broken MPEG decoding, like a low-signal on DVB-S. As mentioned in wiki-documentation, it may be due low speed of USB connection?

[Sundtek]

Enigma is setting up those IDs depending on the channel.

[StAlex]

As I ask before - how can I understand on which PID present the CA messages ? This is to check the HW filtering list.

[Sundtek]

you can capture the stream and look at it with dvbsnoop. All the logic is in Enigma here.

Ok, I'm done with this. I am just take a couple of the days to learning myself about containment of the DVB-streams basics, and what I am found.
Your side take a set of pids from Enigma2 ? Or parse PAT && CAT && PMT itself ?
This is important, because resulting set of pids on encrypted channels is totally incomplete.
This is what using the your side on encrypted channel by default (just switch on to channel and dump the pid set):

root@vuuno:~# /opt/bin/mediaclient -w -d /dev/dvb/adapter1/dvr0
Using device: /dev/dvb/adapter1/dvr0
ID   | PID
----------
0000 | 0x0000 - 0
0001 | 0x00C9 - 201
0002 | 0x00D2 - 210
0003 | 0x00FA - 250
0004 | 0x00C8 - 200
0005 | 0x0012 - 18
root@vuuno:~#

And this - is the dvbsnoop analysis(with cuts to reduce the message size), performed on TS, catched when HW pid filter is switched off (no matter where - on STB or on the PC with the ProgDVB). Missed pids marked as Bold.

Summary, HW filter misses at least two Pids:
CA_PID: 90 (0x005a) - common TS for EMM/ECM transmission
CA_PID: 260 (0x0104) - per channel TS for EMM/ECM transmission

But.
I must to say, if I add this pids manually to pid set, nothing happens. Channels still encrypted.
This is may caused by one of two reasons. Or by both.
1) due to using pairing Conax cam - it needs some more information, than provided by standart pids (90 && 260). It may needs some additional pid. But I am not shure - it is a hypothesis.
2) due to incomplete handshake between smartcard and CAM, the CAM rejects all data incoming from this CA pids, and it affects to the pid set, which your side takes from enigma.

Described here - covers an encryption issue. Not an updating firmware. Firmware issue - is still not cleared for me - how it regulated by EBU standarts (where and how declared additional pids with the new firmware data).
