Beitrag von: labascal am Juni 27, 2010, 02:09:48 Nachmittag
Hallo,

Just realised that this stick has support for Dm800 receiver (MIPS). Would it be posibel or is there any plan to add support for Vu + DUO receiver (also enigma 2 based)?

This receiver popularity is growing very fast, and already got compatibility with other USB sticks (DVB-T),but no DVB-C.

It uses kernel 2.6.18, therfore it shall be supported but when I tried to install the driver I got the following message: checking system... testing libc - FAILED (required libc version >= 2.4, got version: 2.3.90)
If any info is requried, pelase do not hesitate to contac me.

Best regards,

it should not be a big issue, please contact us via skype (sundtek) for further instruction.
Some assistance from your side might be required - eg. providing remote access to your VU - DUO for testing the driver.

The safety check didn't allow to install the driver (it checks the libc version as indicated in the error message). The used libc version is older than the version which the driver was built against. This can be overridden but has should be tested before it can be enabled by default.

DVB-T works, DVB-C itself works too with our 3rd party commandline tools but the VU+ vtuner Interface does not support it so Enigma won't recognize DVB-C directly yet
We tried to contact VU+ and there was no response.

Anyway since we are working on a loopback device we can translate DVB-C to DVB-T in future so it should be possible to get it work after this loopback module is finished it's just a matter of time.

According to a VU+ customer DVB-C is about to work, although VU+ is still fixing up their DVB-C interface.

Message from the customer:

DVB-C working on vu duo with their latest drivers!
I think that there may be some audio sync probelm, and also when initicialization or when the stick cames from standby, it gives an error prior to start working.

I have test on pli image and works nice:

http://www.pli-images.org/forum/viewthread.php?forum_id=65&thread_id=14640 (http://www.pli-images.org/forum/viewthread.php?forum_id=65&thread_id=14640)

You could find also a ipk valid for the pli image that installs it.

As per my uderstanding it shall work on any image that contains the drivers released by VU duo on 1308, that solved VU vtuner issues. However due to the OE change of original image, to make it work on original 5.1 or images based on new OE, the usbkhelper-vuplus.ko shall be recompiled to the new gcc 4.4.3 used by new OE.This shall not be an issue as it is open soruce: http://www.sundtek.de/support/khelper.tar.gz (http://www.sundtek.de/support/khelper.tar.gz)

Hope it is useful!

Minnor issues I found:

+ Automatic scan works on DVB-T mode but not able to make it work on DBV-C
+ Sometimes I think that audio sync problem could happen (small delay)

However in principle it works great.

Ps. Due to file size limitations I cannot upload the files to the post. If posible maybe the administrator could upload them.

    hi all

    contacted sundtek again last night for update on the lip sync issue i reported to them and they forwarded me the email they got back this morning from vu+ support.

    "Dear all,

    New driver, to be released by the mid of this month,

    will resolve all the problems related with lipsync.

    Moreover, some minor bugs will be also fixed at that version.

Hi,

Just received my Sundtek DVB-T/C stick for my Vu+ Duo, and eagerly started to configure it.

I downloaded the latest installation pack, installed it and started the services. All Finnish channels where found properly with auto search.

Now when I try changing to a DVB-T channel, nothing happens. It just keeps rolling the "loading"-icon.

I tried downgrading to latest stable version, but it didn't help either.

I use the latest BlackHole firmware.

Any ideas? Thanks!

Hello Sundtek team and thank you for your constant help and development!
One problem that i need assistance: on Vu-Duo in DVB-C automatic scan doesn't work-it just give me an error message and scan doesn't even begin. Only scans if i manualy insert the frequency-only one frequency at a time...and also needs SR, QAM etc. I don't know all these details from my digital cable provider. Please can you help???
Titel: Re:Vu + DUO support
Beitrag von: Sundtek am Januar 31, 2011, 06:59:29 Nachmittag
Yes for now you have to enter every frequency one by one.
Enigma does not support blindscan with external USB DVB_C tuners at this time.

You might check the DVB-C frequencies with a Linux installation or Linux LiveCD by using Kaffeine or other Linux applications for now.
For windows there's transedit available as far as we know which can be used for scanning for channels.

Hi,

I'm having some serious recording issues with VU+ Duo and two Sundtek USB tuners and I try to figure out where the exact problem is. I'm relatively new to VU+ Duo and USB tuners having recently upgraded from Dreambox 7025 with internal cable tuners and therefore I have not only of course tried a couple of different image distributions (OpenPLI and now VTi), but also installed at least two if not three different Sundtek driver versions usually using the http://www.sundtek.com/media/sundtek_installer_development.sh script. The latest ones I'm currently using are the ones from April 4th.

Now, to the problems: the main issue is that some recordings do not recorded as a whole, they may get recorded for 10 minutes or so or just couple of seconds sometimes. This seems to be related of having multiple recordings going on at the same time.

Also, sometimes the recordings get recorded but they lose sound at some point. The sound may come back after a while or not. It seems that other recordings starting / ending in the background can at least sometimes affect this, although I have not confirmed this. Yesterday I witnessed a situation where two recordings from the same multiplex ended at the same time and the live picture (also from the same multiplex) lost sound. Service selection brought the sound back.

I did some investigation and noticed that I had an older version of the VTi image (2.4), having drivers from February, so I updated the DVB drivers from the official VU plus site to the latest ones. However, this did not at least completely solve the problem, since after that I made some test recordings, having 3 simultaneous recordings from one multiplex and two from another one and one of the recordings (a one from the multiplex that had 3 recordings at the same time) did not have the sound.

Anyway, as I said, I basically wanted to ask whether this might be a problem in Sundtek drivers or is it the VU DVB drivers that are causing this? Knowing one or two things about the DVB because of my work background, I would imagine it could be a problem of certain PIDs not getting recorded, maybe even a demux limitation of some kind, but you of course know much better which part of the recording procedure is handled by the VU drivers and which part is under the Sundtek drivers and hopefully have a clue where to start looking to get this fixed :) 
Titel: Re:Vu + DUO support
Beitrag von: Sundtek am April 12, 2011, 01:37:20 Nachmittag
So the recordings loose audio after some minutes or just from the beginning on?

We have heard about an audio issue sometimes with some channels but that was unrelated to our USB Stick so far.

One more thing to add, if you log in via telnet to your VU+ you can run following command in order to show which PIDs are selected on which device:

/opt/bin/mediaclient --lc

So if you know the Audio/VideoPID of the corresponding selected channel you can cross check if VTI has told the driver about those certain PIDs, and ultimatively the question is if the audio PIDs are in the recorded files and if it is just a playback issue.
Once this is known we know where to put the Bugreport, either to us or VU+.
Titel: Re:Vu + DUO support
Beitrag von: unreal am April 12, 2011, 02:22:23 Nachmittag
Thanks for your response.

Sometimes the audio is not there from the beginning and sometimes it disappears after few minutes and it can sometimes also come back after a while. Same goes for the recordings ending unexpectedly: sometimes they end immediately after starting and sometimes they go on for 5-10 minutes and then suddenly stop. However, if you go back and forth in a recorded file having audio issues, it always disappears and comes back at the exactly the same point, so it looks to me that it is in the recorded file and not in the playback. As I said, this might be related to other recordings starting and ending in the background while recording, but I'm not 100% sure.

As soon as I get another recording with problems (unfortunately the ones that had issues have already been deleted), I will run the mediaclient -lc and get back to you with more information.
Titel: Re:Vu + DUO support
Beitrag von: Sundtek am April 12, 2011, 02:30:57 Nachmittag
hmm the problem is that command is only useful during a recording, but you can still crosscheck that way.

If you have such a file can you provide us a sample so we can check the videostream?

Additionally you can check the signal strength:

Zitat
/opt/bin/mediaclient --readsignal=0 -d /dev/dvb/adapter1/frontend0
or
/opt/bin/mediaclient --readsignal=0 -d /dev/dvb/adapter2/frontend0

If Audio just disappears there are could be a few possibilities (also shows up who is responsible):
* Signal strength issues (Sundtek)
* USB Performance issues (VU+/Sundtek)
* Codec issues (VU+)

Ok, good to know :) I'll try to find some time to do some testing today, hopefully I can reproduce the problem by just adding some random recordings, taking the pid information and then check if any of the recordings has problems.

Signal should be fine, at least every time I've checked the values, they have been near perfect. Also, I have seen no problems in live signal when I've had no recordings or in the recordings (or live) if I have only one recording at the time, which also I think makes the signal issue unlikely. However, it is not a big task to confirm that as well anyway while I'm on it.

As far as the codecs go, there seems to be another issue with Dolby Digital tracks in general, them not being played when I enter a service with DD sound track and I need to go and put the "downmix" setting on and off again to get the DD audio tracks played, but I do not think the recording audio issues are related to that. All the recordings with audio problems have been pretty basic MPEG2 SD video / one PCM stereo audio track stuff, so nothing special with the codecs at all.

Anyway, I'll get back to you this evening once I get some testing done.

Beitrag von: unreal am April 13, 2011, 12:00:27 Vormittag
Of course, the testing I had time to do today did not reproduce the problem, at least not in a way I described it. I was able to complete 4 recordings at the same time, three from a same multiplex and every recording had the sound in place.

However, I did notice that during the test recordings, there was once a "timeout reading PAT" after changing a channel and during the playback of one of the recording I saw a PMT timeout dialog, otherwise they were now working fine. Also, all of the "real" recordings from tonight seem to be ok and there was at least one 10-minute period where four recordings were on at the same time, all from the same multiplex. So, after a very short testing period it seems that updating vuplus drivers at least made this better, even if it is not perfect yet. In the release notes of the latest drivers it says "Increase the number of demux device", so maybe it is some kind of demux resource problem and hopefully they will make it even better in the future...

In case you want to take a look, I do have the recording file that has the "PMT timeout"-problem when you play it back and also some mediaclient --lc output from the time of the recording, but at least for now it seems it might be a problem in the DVB drivers rather than Sundtek drivers.

If PMT Timeouts occur please check the signal strength.

Zitat
/opt/bin/mediaclient --readsignal=0 -d /dev/dvb/adapter1/frontend0
and/or
/opt/bin/mediaclient --readsignal=0 -d /dev/dvb/adapter2/frontend0

Signal strength was 99%, BER 0 all the time when I monitored it yesterday. Also, PAT / PMT errors, like all the other problems (audio disappearing and recordings ending unexpectedly) only appear if there are some recordings at the same time, I've never seen those if there are no recordings in the background at the same time.

A little correction to my report from yesterday, it seems that all the recordings from the evening were NOT ok. One of the recordings had ended after 40 minutes when it was scheduled to end at 1 hour and 10 minutes. The recording may have ended at the same time when either a live channel was changed in the box or, more likely, when my wife started to watch a previous recording from the hard disk.

I will take a look at the recording file a little later with a TS analyzer to see if it gives me any clues what went wrong before the recording unexpectedly ended. I will also take a look at the other recording (the one that had PMT errors) on PID level and see if there are any clues.

What does your setup look like?

1x watching DVB-S?
1x recording DVB-S?
2x recording DVD-T?
Titel: Re:Vu + DUO support
Beitrag von: unreal am April 13, 2011, 03:18:45 Nachmittag
What does your setup look like?

1x watching DVB-S?
1x recording DVB-S?
2x recording DVD-T?

The setup is 2xDVB-C, used for both recording and watching. Sat tuners are of course there, but they are not connected / used, I don't even own a dish :) So, everything comes to the box through the two Sundtek tuners that are in the DVB-C mode.

I now looked at the problematic recordings with a stream analyzer and noticed a couple of things:

 - The recording causing the "PMT timeout" error actually has no PMT at all. How that is even played back is a bit of a mystery to me (maybe the box looks at the content of the PIDs and decides what is video and what is audio?), but all it has is the PAT and the audio, video and teletext PIDs of the recorded service.

 - The recording that ended unexpectedly 30 minutes before it should have been seems ok otherwise, but maybe ten-fifteen seconds before the end of the stream, the bitrate of the PAT seems to go crazy, jumping from (normal) 6-7 kbps to several hundred kbps and back and finally a second before the end of the stream it goes to 1,5 Mbps... not sure if these values can actually be true (I'm using Dektec StreamExpert for analyzing that I have at least previously found relatively reliable), but something strange definitely happens with it since that kind of behavior does not happen with the recordings that have ended normally.

 - In the recording where the audio disappears after around 1,5 half minutes, the pid is there first, with normal bitrate and then suddenly the bitrate drops to zero and the sound of course disappears at that moment. After that, the analyzer shows the PID as "ghost pid" because it is still in the PMT, but there is no data in that pid anymore.


I would think these problems are all somehow related, but without knowing the details of the drivers etc. it is of course impossible to say much more about the potential reason. Overall, it seems that once more recordings / playback is going on at the same time, the PIDs start to drop off from the recordings / live playback.

VU+ is also following this discussion now.

Ok, good to know.

I have basically now written everything I know about the problem here, but I can still report if something new comes up. I still have the recording files for each individual problem (PMT missing, sound disappearing, recording ending unexpectedly) if you or VU+ want to investigate them, but since they are relatively large files, I would prefer an external location to upload them to.

Basically what I would like to find out (I'm sure you and VU+ would, too ;D) where exactly the problem is and if I could avoid it somehow, by changing software image, updating / downgrading drivers or something like that. Of course I know I could probably avoid it by recording only one program at a time, but that just does not seem reasonable given that I only upgraded from my old Dreambox (that could easily do 4 recordings at a time) to get a box with a better hardware in terms of processor, memory, flash etc. resources. The biggest issue I think is the unpredictability, sometimes the recordings seem to be error-free even if there are 4 recordings at the time and sometimes issues occur with only two simultaneous recordings, maybe due to difference in what has been done at the same time (changed channels, watched previous recordings etc.)

Any news on this? It's still happening every now and then and it is really annoying not being able to trust that recordings are correctly recorded. Is there something I could try to do, update / downgrade etc?

Hi,
I run ViX 2.1.4 and the Sundtek runs very well :)

I've the problem with the DD audio thou. All mpg audio works ok. Now if I change to channel with DD audio, there is no sound. I have DD downmix set to NO as default. If I turn the DD downmix to ON the audio appears as expected. If I turn it back to NO, the sound disapears but after appr. 5 sec the DD start to work as it should. If I change the channel again I have to do the downmix trick again for any DD audio to be sent to my receiver.

If I record the show with DD and no downmix turned ON, it plays back with DD audio working perfectly (no trick required).

Thanks

Hi,
I did get second Suntek (same home edition) which still has the same DD audio problem. But on top of this the "fail tune" message pops out every few days and only the box restart will fix it. Is there any firmware versions availible for those sticks?

Thanks

EDIT: according to DD audio issue I do use HDMI output and maybe this is the problem?

We reported this again to VU+

Unfortunately from our side there's nothing we can do here, we can just pass the audio data to the VU+ system and rely on the decoding of their interface.
What we can imagine is that the interface is hardcoded to mp2/3 on their side, let's see what they will reply to our last emails...

It's a little bit difficult to support VU+ at this point different images use different VU+ drivers with different features.

We shipped several DVB-S/S2 devices to the VIX team, please send the problem report to the VIX Forum.

Is there some command which i can use to check version of my sundtek drivers?
or how i can be sure that stick firmware is updated?
Titel: Re:Vu + DUO support
Beitrag von: Sundtek am März 11, 2012, 04:13:33 Vormittag
Once you install the latest drivers it will update everything automatically.

Although for checking the Version on settopboxes you can run /opt/bin/mediaclient --build for Dreamboxes /usr/sundtek/mediaclient --build  (this will give you the date of the driver release)

Hi,

I have a VU+ Duo box with Sundtek MediaTV (early 2011). It has quite never worked perfectly. I quite only watch satellite channels instead of DVB-T ones (Finland), so I haven't payed that much attention until recently.

I had installed the latest Blackhole image and latest Sundtek drivers. It took about 5 minutes after boot before the picture would either stop or play a 1s loop. If one tries to change channels is says PAT not found (if I recall correctly). Enigma reboot does not help.

I now changed back to original images and thought it would help as suggested in some thread. Now the frequency is days or weeks instead of minutes.

What should I do, I'm getting quite frustrated.

Thanks,
  Henrik

You might try to contact our support via skype chat "sundtek" in order to check what's going on on your side.

Maybe setting the devicemode to bulk by running following command:
Zitat
/opt/bin/mediaclient --dtvtransfermode=bulk -d /dev/dvb/adapter1/frontend0

might help. However it's a little bit difficult to identify without having direct contact with you.

alternatively you might try: http://chat.sundtek.de (depending on the time you might also get some support there).

What this command will really do?
If I'll give this command will it last after reboot also?

I changed Vu+ DUO image from BlackHole 1.7.8 to OpenVIX (Newest build) and I see this same issues what flc has seen. There wasn´t this kind of issue with BH it do work like a charm. So what to do, is there working workaround?

Problem starts maybe after one day. Reboots help to get clear picture again for a while.


I do have 2x Sundtek Pro. First one is used for C-channels and second for T-channels, both sticks are connected to active USB hub.

I have used 13.11 drivers with BH and OpenVIX.
root@vuduo:~#  /opt/bin/mediaclient --build
Build date: 2012-11-13 17:48:18

I have used this kind of sundtek.conf

root@vuduo:/etc# cat sundtek.conf
[tek00147]
initial_dvb_mode=DVBC
dreambox_support_fe1=on
[tek001477]
initial_dvb_mode=DVBT
dreambox_support_fe1=on

If it works with one image but not with another one the bug will be in the image of the box and not on our side. Maybe try to swap the VU+ drivers from BH to your new system, they are in /lib/modules
Titel: Re:Vu + DUO support
Beitrag von: rassi am November 29, 2012, 12:09:44 Nachmittag
Thanks. Looks like BH did have modules from 20120820 (not 100% sure about this) and VIX has drivers 20121025.
I´ll give a try.

But how about that --dtvtransfermode=bulk?
If driver change do not give help, this can give?

Beitrag von: Sundtek am November 29, 2012, 12:16:43 Nachmittag
dtvtransfermode is obsolete within the last driver versions.

Ok.


From OpenPli forum

Zitat
I am running open pli 3.0 (2012-11-12), sundtek drivers 121027.112338 (I experienced some problems with later drivers, didn't test the newest ones), oscam-experimental. I have two usb dvb-c tuners connected to two rear usb ports without any hub and everything works ok. Finally!!!

How i can install older drivers?  ???
If i'll try that one first or try latest ones from you.. If there has anything changed to VU+ from 13.11 to 27.11?
