Hey OpenPli team,

Enigma2 freezes when I zap to a DVB-C channel. Could you help me?

Traceback (most recent call last):
  File "/usr/lib/enigma2/python/Navigation.py", line 49, in dispatchEvent

Hopefully this is fix tomorrow.... As I cannot check it I'm not 100% sure .

[atilaks]

Thanks. Modified Transponder.py from another thread solved my problem. However this is just a quick and dirty solution, so I hope sundtek will fix the problem soon.

Hi again,

Could you also take a look on pliExpertInfo.py (lines 78:96) and add some checks for frequency, symbolrate and fec_inner? When zapping to a dvb-c channel values are null and enigma2 crashes.

http://openpli.git.s...3a17d987e459dba

Thanks.

[littlesat]

So PliExtraInfo.py is fine now and pliExpertInfo.py is still "crashing"?.... please note pliExpertInfo.py is principally obsoleted.... it is only there for skins that do not adjust (yet) to PliExtraInfo.py....

In fact the issue is that the tuner is not returning the correct values as they are not fully DVBAPI 5 compatible.

Based on the structure of pliExpertInfo the easiest solution is to put a try/except structure around this code - or (better rewrite) to check the values for being having a value before doing a calculation.

But because I consider pliExptertInfo as obsoleted I would recommend to use a skin that does not use this anymore.

[atilaks]

Yes, I switched to Holi's SimpleHD skin and pliExpertInfo was crashing, so I fixed pliExpertInfo by hand, just to get it to work.

I will ask Holi to update his skin.

Thanks.

[littlesat]

I would prefer these skins change to pliExtraInfo.... ... Finally I can just remove pliExpertInfo...

[atilaks]

agree, I asked Holi to switch to pliExtraInfo

[littlesat]

so I fixed pliExpertInfo by hand

Could you post your fix here?

Here you go.

Hi littleat,

Can you point out to which values are wrong?

[pieterg]

the problem is not that parameters are wrong, the driver returns no parameters at all (when using FE_GET_PROPERTY).

[sundtek]

the problem is not that parameters are wrong, the driver returns no parameters at all (when using FE_GET_PROPERTY).

FE_GET_PROPERTY is fully supported with the driver, reading FEC, Delivery System etc. is no problem. Linux VDR and some Linux Applications are using it for a long time.
We've seen some issues with FE_GET_PROPERTY in the past with some vtuner/broadcom module versions, do you think that might be the issue?

our openpli buildsystem is ready so far. we'll have a look at overriding the dvb commands and submitting it directly to the driver soon.

[sundtek]

As mentioned earlier already, we can give away some samples for E2 developers if there's some interest about it.

[pieterg]

The driver returns an invalid result on FE_GET_PROPERTY, so I think it does not even get forwarded to your code.
The dmm vtuner driver probably has no dvbapi5 support.

[littlesat]

So as work-a-round we should/could re-enable usbtunerhelper for the DMM boxes....

[pieterg]

no, that won't help

[littlesat]

[atilaks]

well, the device works like a charm, I can live without freq and fec on my screen until sundtek or dmm releases a new driver...

[littlesat]

until sundtek or dmm releases a new driver...

Sundtek is not the issue here
