Hi,

Attached patch makes the pct452e working for me with S2API
based on changeset 9263
http://mercurial.intuxication.org/hg/s2-liplianin

- mostly cleanup (remove commented code)
- proper frequency reporting for stb0899 (dvb-s and dvb-s2)
- fast and always lock for DVB-S (up to 8MHz frequency offset allowed) (only tested with symrates: 22 and 27.5)
- DVB-S2 checked 19.2E 11915 H 27500 only (I cant test others)
- PCTV452e LED  green: FE open    orange: FE closed
  does the TT S2 3600 (3650CI) also have this led and is it attached to the same GPIO?

What I still dislike is the very long blocking if no signal is found or wrong parameters were specified.
This could be easily avoid: if there were a signal locking would be quite fast ;)
But i haven't had time to search for the solution to speed up... 

also attached simples2apitune which is same as simpledvbtune but for S2API

happy testing,
 Dominik

Hi Dominik

I will test it today with s2-3200 and give you feedback
And thank you.

Hi Dominik!


> - fast and always lock for DVB-S (up to 8MHz frequency offset allowed) (only tested with symrates: 22 and 27.5)

yes channel lock is very fast and it always locks, i had no problem
locking on DVB-S with 30000 symrate.

> - DVB-S2 checked 19.2E 11915 H 27500 only (I cant test others)

it locks fine on 13E DVB-S2 channels (27500)

> - PCTV452e LED  green: FE open    orange: FE closed

The LED is working on TT-S2-3650CI

> also attached simples2apitune which is same as simpledvbtune but for S2API

simples2apitune is not working for me on both DVB-S and DVB-S2.

[faruk@archer simples2apitune]$ ./simples2apitune -f 10975 -p h -s 27500
using '/dev/dvb/adapter0/frontend0' as frontend
frontend fd=3: type=0 name=STB0899 Multistandard
ioclt: FE_SET_VOLTAGE : 1
Low band
set tone: 0
set symbol rate: 27500000 Sym/s
set frequency: 1225000 kHz
do tune....
tuning qpsk failed

Dominik are you too facing packet losses from TS?

Thanks
Faruk

Oh yes, I haven't set the return value...
please find attached a new version which has that issue fixed

yes, the return value of set_qpsk_channel() is random :(

Not in the streams i have tested so far.
how often and on which channels do you get errors?
what is the SNR for them?

Thanks for the feedback,

To me, nothing changed. There is no lock for 3255 and 44948 kSym/s and there is packet losses for 
27500 from time to time.

But I will bear in mind your patch for future, when the problem will be resolved.

I get image distortions on all channels.
I have tested with vdr, kaffeine and szap-s2 + mplayer/vlc/xine.

Is the same problem we had before back in February/March and then you
fixed in the final release.

Never mind that, i think there is something wrong with my device. I
have the same problem in windows xp and vista.
The channels are working fine on my set top box (Samsung DSR 9500 VIA
CI) which i haven't used in months
since i bought the tt-s2-3650.
