[linux-dvb] Measuring signal strench on TT S2-3200

[SKOČDOPOLE Tomáš]

Hello,

For quick test I used getstream utility. Later I am planning to use vdr with some plugins for streaming. 

I have parabola directed to 23.5E (Astra 3A/1E). I tested two FTA programs Ocko and CT24. On second computer there was VLC running. I think parabola is directed correctly, because I have borrowed desktop receiver and there was no problem with these programs.

I tried latest drivers from Igor M. Liplianin but I have the same problems with multiproto drivers.

When I was streaming Ocko, on second computer there was good screen, but sometimes (aprox once per 30 seconds) was shortly breaking.

When I was streaming CT24, it was running only for max 10 seconds and then getstream utility stopped sending stream packets.

There is debug output from getstream utility:

Hi, 

Now, I am using latest drivers from Igor M.Liplianin and these problems should be fixed. Now video runs without any blackouts or errors... Great work!

Igor, I want to ask you about progress of scan and szap utilities for dvb-s2.

Best regards
Tomas

Hi Tomas
It is in my priorities list, but after completing some drivers
I already started writing ( patching? ) scan utility for dvb-s2.
szap2 & szap-s2 are working now. So, let's wait and see.
Hope there are peoples, which may developing quicklier :-)
Night is my only free time :-(

Igor, you are doing a fantastic job. I thank you for helping with all of 
the patches and the utilities.

I will from the plumbers conference in the next few days and I expect to 
merge a number of patches that are sitting in my inbox.

Thanks you again for helping with this.

Regards,

Steve
