Latest TBS Linux driver package doesn't appear to work with TBS6905 card

Just a quick heads up for anyone with a TBS6905 card that uses the standard TBS drivers, you might want to skip the latest tbs-linux-drivers_v160405.zip package because it causes the TBS6905 to incorrectly identify as a TBS6908 and then the tuners will not work, at least not in TVHeadend.  Going back to the previous tbs-linux-drivers_v160219.zip package fixes the problem.  Or at least that is my experience on my system running Ubuntu Server 14.04.

The TBS6905 tuners identified incorrectly when using "dmesg | grep -i dvb" from the Linux command line, so it wasn't just a TVHeadend issue.

Old 716x based card based DVB-S PCIe in Linux

April 11, 2016, 8:34 am

Hi All,

This might be a long shot but since we do have some Linux gurus on the board I figured I'd would ask...

I have an old AzureWave DVB-S PCIe AD-SE200 card, it's basically a Twinhan VP-1028 card, and I'd like to do some tests with it in my Linux box. The card uses the 7160 and MB86A16 chips.

I've followed the instruction at github.com/ljalves/linux_media/wiki/Installating in order to get the open source drivers built but when I load the module I get the i2c_xfer error. This happens on both Ubuntu 14.04 (kernel 3.13) and 16.04 (kernel 4.4.0). 

Code:

...
  saa716x_dvb_init (0): Frontend Init

...


I've googled and there are other people having this problem but no solutions (or no answers). I'm not afraid of some C code since that's what I do for a living, but I've never done drivers. 

Any help would be appreciated.

TSREADER and HEVC

April 11, 2016, 1:35 pm

  I was pulling my hair out (not many left) all weekend trying to play the HEVC 4K Masters, and my main issue was that TSREADER doesn't recognize the A/V PIDs in a 4K stream. 
So in hopes that newer versions of TSREADER had fixed this, I upgraded to the newest TSREADER. 
I THOUGHT that I had installed it, however in my stupidity, I mistakenly installed an even older version of TSREADER, and of course, it didn't work any better.
   Today, I finally realized what I had done, and installed the right version.  It's obviously too late for the Masters feed, but I decided to try it on the NASA 4K channel.  TSREADER recognizes the HEVC video just fine, and streams it fine to MPC-HC.  Plays without any hiccups.  Of course, the Masters feed was a much higher bitrate, so it still may not have worked, but it is nice to be able to stream 4K signals from TSREADER.

Dedicated Distro??

Has it ever been discussed or thought of, to create a dedicated Linux Distro for x86 for DVB??  By dedicated, I mean that is all it does.  My thought being, that if made simple and solid enough, anybody could download it and install it, then use their PCI or USB receiver without any further effort. (Assuming they had a supported PCI or USB receiver.)

Just a thought.  Know there are more active Linux users/developers here, so thought would pose the question.

How hot should CPU in computer get??

April 12, 2016, 1:51 pm

I've been playing with the NASA 4K today.  Had it running for quite a while, like for 45 min or so, but it eventually sort of turned itself off.  After it did this a second time, I started wondering if it were overheating.

My computer has Intel Graphics on board, so much of the work that would normally be done by a video card is done via the motherboard, although I'm not sure how much of that is done in the CPU vs the on board Intel chip. 
   But anyway, worried about temperature, I ran a program that monitors core temperature.
Before I start playing 4K video, the temperature was about 24 deg C.  Once the 4K video starts, the temperature rises to about 70 deg.  Occasionally it gets up to around 75, but usually falls back down to a bit below 70.  70 is around 158 deg F, which seems pretty warm.  I think the CPU was running about 45% and around 45 watts on this channel.   The CPU apparently has a Tj max temperature of 100 deg, which I guess is where it will shut off, and I don't seem to be getting close to that, but I'm wondering if running at 70 deg would be doing any damage to the processor?? 

I think this is talking me into getting a regular video card instead of using the on board video since that should keep the CPU temperature down, and if the video card gets damaged, that can be replaced easier.  People here have mentioned getting cards like GTX-950, but there are a whole spectrum of similar cards, both cheaper and more expensive.  All the reviews on the cards seem to relate to gaming, and not to playing video, specifically to how fast the video reacts to the keystrokes or something like that, and that doesn't seem that important for playing video.  Just curious re to what extent the gaming speed is relevant to taking the load off the computer's CPU.  Seems like as long as it does hardware acceleration, that's all that's important.
   Mainly looking for recomendations re what cards are good / better/ best.  I assume something like the 950 would be in the middle, and something like a 980 best, but are they both overkill, and something else might be fine?

updateDVB forks

I've forked updateDVB to start with some graphics changes, and hopefully to progress from there.  Rather than hijack the updateDVB thread, I've forked that thread too. 

I'll start with a response to observations/comments made by bluzee ...

The fact that you have green dots is great news, but it probably means that it's likely a driver issue with my card.  I'll have to look into that, but it's a good start that it's willing to render a satellite scan for somebody

Secondly, that's forced me to think about how to achieve an easier to click transponder.  I did have the hover event change the opacity of the object so that the user would know that they are on it, but I know even my eyesight's not what it used to be (once you hit 40 ... wow), so I get it.  Also, maybe not taking the screen size into consideration.  Maximized on a 50" TV is a little easier.  BTW, what screen do most people run updateDVB on?  I'm using the TV because that's where all my tuners are connected ... the HTPC.  Is that a fair assumption, or are people using laptops and USB tuners, which would be harder based on screen size alone.  Don't know how hard it would be, but what if I had the dot expand when passed over, or had some sort of magnification (now I'm really working myself into a tough corner)?

Anyway, really appreciate the feedback.  Keep it coming, and I'll see what I can do.

Will this change affect on my TBS 6908 ??

Hi,

I have a problem of my LNB.The problem is to have the a signal of a right transporder, I must reduce the transporder by 66 MHz. For example, to have signal of 11766, I must put it as 11700..

This must be done with transporders from 11700 to 12750 ranges.

Some friends advised me to increase the amount of the LOF2 at the LNB setting.So I increased it from 10600 to 10666 through CrazyScan,EBSPro and DVB Dream. Therefore, I had the signal of right transporders. I was very happy..But I am afraid that this change affects badly on my TBS efficiency !!!

Hi,
I tried different versions of CrazyScan and  EBSpro, I found that the number of scanned transporders on CrazyScan is more than on EBSpro when I do Blind Scan.
For example,  If I find 60 TP on EBSpro , I find about 70 TP on CrazyScan!!
Why?

I just received my new TBS5925 USB tuner from Rick (thanks Rick) and I have a question. One of the programs on the installation CD was TBSViewer. Does this program only work with the PCIe versions of TBS tuners? I installed and even downloaded the newest version along with updated drivers but when I start TBSViewer nothing happens but I can see my computer allocating resources to the program. Weird.

Prof 7301 and H&I

Anyone else noticing any problems using a 7301 and tuning H&I (  3952 V 2734 )
What I am experiencing is an almost consistent cropping and signal drop out when tuning this TP.
Seems to do this in both MediaPortal and DVB Dream. Also will cause another STB to do the same if using loop through. Using the latest drivers with WIN 7 64 Bit I can locate.
Seems to make no difference using switches or straight through..have tried 2 different dishes with different LNB's just for kicks.

Any ideas appreciated.

KODI add-on to decode 4:2:2?

?? H264 / 4.2.2

I'm curious re what's the deal with channels with H264 / 4.2.2 video?
I know I've read posts here about it being difficult to play, but I guess I've never run into one of those feeds, so I didn't pay much attention. 
    But I've been looking at the 4030 V 15000 transponder on SES2.  Yesterday, I played it for a minute or so before moving on to other transponders, but today I tried watching it for longer periods of time, and noticed that after a minute or two it started to break up audio wise, and I think go into slightly slow motion on the video, even though there was not much CPU load, and no noticeable errors on the signal.  After fighting with it for a while, I finally noticed that it was H264 / 4.2.2 .  
   It was giving me problems with both VLC and MPC-HC.  The strange thing was that if I didn't play it full screen, then I didn't seem to get the breakup or slowdown, which didn't make any sense considering that the player was using very little CPU time.
   Finally, I tried PotPlayer, and it worked just fine.  Been watching it for quite a while now with no problems at all.
Is this just an issue with the CODECs or something? And if so, it seems like it must be that the codecs have bugs, not that it's a processing overload.
     Anyway, I'm curious what the current situation is.  It seems like a year ago people were saying that they couldn't play this format, but now, it seems like it's possible with some players, or by not going full screen.
   Or is my memory bad, and this was never an issue?

In any event, I really like the deep colors I see in this feed.


EDIT: SmartDVB plays the channel too, with only a occasional spasms .  Spasms starting to get more numerous.

Jumping Out Of Windows

This forum, more than anything, brought me from shortwave radio into the vast world of satellite radio (and a little television).

I would really appreciate some help now that I have suffered the indignities common to all Windows users and now have an newly-configured Linux Mint 17 drive for dual-boot.

My goal is to move all existing capabilities from the Win 7 to Linux, even if I have to change applications (AND walk on hot coals) to do it.

I AM on a mission here.

I have already discovered I have to loose DVBviewer, which I really liked, but thems-the-breaks...

This is my stuff:
I have an 8-foot-solid, Norsat C and KU, with a PROF-8000.

Like I said, I like DVBVIEWER, but whatever. I ALSO REALLY like Crazyscan and Transedit.

What is my best path (short of buying more HW!) to get to Linux and end up with:

1. Satellite Spectrum analyzer (today Crazyscan)

2. Transponder Stream Analyzer (today Transedit)

3. DVB S2 Viewer/recorder (today DVBViewer)

I have big faith you guys will be able to guide me out of the windows.

Thanks!

UpdateDVB Tweeks?

So here I am, pulling myself up this steep linux learning curb, but I've re-established that I could still make "updatedvb" work as well as I had last week.

It's all pretty well set up now, but I'm also afraid I redetermined that the analyser blows-up when I try to open the most populated AMC-8 Transponder on 4150 SR 9259

I get the CNN audio there!

I have pretty good insight into the unusual way this satellite is set up.

I'm hoping someone could give me a clue as to why the app is blowing up on here.

The big obvious differences with this TP are:

1. There are no video streams
2. There are LOTS of audio streams alive and..
3. There are MEGA-lots of channels in the BAT and other listings.
4.  There is some strange thing about these streams actually lack a valid time-reference (PCR?"). Some audio apps refuse to play the MP2 w/o that.

The Transedit program gets messed up on this TP as well, but the problem is there is a 128-channel discover-limit (I discovered on other TPs this limitation as well).

Any Radio-Linux-Heads out there that have something working right on this TP?

SmartDVB database

Hello:

I don't know much about databases, so this may sound like a dopey question.

Is is possible for two instances of SmartDVB to be accessing the SmartDVB data file at the same time ?

What I was wanting to do was create a network share with the database, and access this with a second machine running SmartDVB, with a second TBS board and diseqc motor. I would use this for blindscaning, while watching news feeds on the first machine.

This would be great for watching the news in the morning. If there is a way for both instances of SmartDVB to access the same database, I could watch the feeds on the first machine, and use the the second to auto populate the transponder list.
