KLCP 11.9.6 blocks DVB analysis!

Post by vramor on Sat Feb 20, 2016 5:10 pm

After and hereupon(!) upgrade KLCP to 11.9.6 some problems have arised with DVB-T/T2/C receiving by USB PC-tuners. The transport streams are simply not analyzed anymore because KLCP v11.9.6 doesn't permit do it.  For example, TransEdit has end up to see the TS content of DVB-T/T2/C transport streams using GoTView MasterHD 3/5, GeniaTech T220A/T230, TBS 5880, etc. The same story with ABC Content Analyser.There is no problem with KLCP v11.9.4 and earlier. It seems that something goes wrong during upgrading process to 11.9.6, because the uninstall of 11.9.6 and reinstall 11.9.4 or even 11.8.0 doesn't solve the problem. The problem can be solved only with recovery image that contains an earlier version of KLCP.

If reverting to an older version does not work, then it is very likely that the problem is caused by something outside of the codec pack. Maybe a Windows update?

Do those tools even use external codecs?

I don't use automatic updates neither in Win7, nor in Win10. Everything is under my own control. The problem appeared in Win7 64-bit. It repeated statedly, i.e. there is no problem with 11.9.4, then I update to 11.9.6 (nothing else!) and the problem appears. I uninstall KLCP at all, then install any version of KLCP, for example v11.8.0, and the problem remains. Then I take the Acronis' image with KLCP v11.9.4 (thanks God I've got it), recover, and everything becomes OK. Then I upgrade KLCP to 11.9.6, and the problem arises again. I have to recover once more to get rid of the problem.
My tools use LAV and ffdshow codec, all from KLCP. What can be outside of 11.9.6 update?

Do any of those tools work with files as input? So I can try them. I don't have a tuner.

Were you using 11.9.4 installer, or 11.9.0 + update pack?

The problem tools use transport streams received by tuners as input. There is no problem with files. It seems that splitter (LAV and Haali) cannot manage with TS using the tuner's driver. So this particular driver can be the reason of the problem.

11.9.0 + updates. Now I decided to give up the particular tuner and its driver to solve the problem on my work PC and to continue try with another computer under Windows 10.
Thank you for your attention!

So the driver was the problem? Did you use a different tuner/driver before?

This is my supposition. The drivers from Turbosight company are under suspicion. I did not encounter a similar problem with tuner/drivers from another producer.

I use many tuner/drivers from different producers both DVB-T/T2 and DVB-C. I did not notice such problem until I upgraded KLCP from 11.9.3/4 to 11.9.6, but with Turbosight's products only. Now I put aside these products and uninstalled its drivers. The remaining devices are OK so far. Just in case I left 11.9.4 version of KLCP. Smile

Does the Turbosight one work with 11.9.4?

In DirectShow there are two modes for how a source can deliver data to the splitter: Push (source pushes data to splitter) and Pull (splitter asks for new data when it needs it). LAV Splitter and Haali only support the Pull mode. Could be an explanation.

No, it doesn't! Right now I took another PC with 11.8.3, tried TBS, everything's OK. Installed 11.9.0 (quick), TBS works normally, upgraded to 11.9.4, TBS stopped work normally, i.e. behaved with some apps and misbehaved with other ones. By the way my working image containes 11.9.3, that's why all were OK when I used it.

Yes, it would be greatly appreciated.

You said that files played without problem. Is that also true when you record a stream with TBS? Having a file that gives problems would be very useful because then it can be reproduced by the developer of LAV Filters, which makes fixing a potential bug much easier.

Yes, I can play any file with MPC-HC without problem including files containing MPTS, which were recorded earlier. But I cannot record TS with TBS device/driver after upgrading KLCP to 11.9.4/6 as well as watch it, because of the splitting process is not executed. Meanwhile I can record TS with another device (not TBS) at the same time and play it then with MPC-HC (KLCP 11.9.4/6).
I think that the reason of this weird behaviour of TBS products is their departure from the BDA norm. Nevetheless it is very interesting why it appeares with KLCP 11.9.4/6. I'll try to check it more thoroughly.

I've found out the reason. It all depends on Windows! First of all I took the clear PC and made sure that everything works perfectly with all the KLCP version. Then I came back to my work horse PC and uninstalled all the drivers of TBS devices (there were 3 drivers for 3 various devices installed). After this I reinstalled the proper driver on it for 1 device only. The problem disappeared.
