"PMT BUFFER OVERFLOW, PLEASE REPORT!" #79

Closed CReimer closed 9 years ago

CReimer commented 9 years ago

Am I right with this here, or should I report that to oscam directly? I do not have more logs, because I don't had vdr-dvbapi's loglevel on 3 while this happened.

Here's a set of logs (VDR+OSCAM). Now with loglevel on 3 https://gist.github.com/CReimer/762f03eb7c11e4a2b803

At the moment it looks like this overflow happens in a 30 minutes interval

manio commented 9 years ago

I can see that the PMT data is very big (sending len=1366). This could be the problem, because the buffer in the OSCam is smaller. There could be various reasons - maybe the data parser is wrong. I have to analyze it. On what channels you have it? Is it working despite this error?

3PO commented 9 years ago

Checkout SkinDesigner, this revison (or newer) and your Problems are gone: --> http://projects.vdr-developer.org/git/vdr-plugin-skindesigner.git/commit/?id=f9f68cae8d64f5c60ffaa34118b66f5ebab28506

CReimer commented 9 years ago

This has nothing to do with skindesigner as this plugin wasn't even loaded at that time.

@manio: I think it only happens while two channels are decrypted. It's happening with all encrypted channels I tried.

manio commented 9 years ago

@CReimer 3PO was probably talking about issue https://github.com/manio/vdr-plugin-dvbapi/issues/77 which you've suffer...

and about this issue: besides this PMT error, are channels decrypted correctly or freezes?

CReimer commented 9 years ago

Everything works as expected. No visible problems at all. Also softhddevice doesn't complain about broken frames or anything.

manio commented 9 years ago

@CReimer Can I close this ticket now? Or you still have such problems?

CReimer commented 9 years ago

No. I think, whatever it was, is gone.

manio commented 9 years ago

Ok, thanks :)

CReimer commented 9 years ago

It's back... My ORF cards somehow stopped working in Cryptoworks mode. So I switched it into Irdeto Mode.

It's exactly the same as before:

socket_fd=7 len=1213 wrote=1213

and

Unknown socket command received: 0xC6EBD78A ***** WARNING: PMT BUFFER OVERFLOW, PLEASE REPORT! ******

in the oscam log

3PO commented 9 years ago

This is not a Problem of the dvbapi plugin.

My ORF Card is working in ICE Mode as expected:

I think it may be some temporary problems: it was working for fine for several months and now it appears again in your case. The unknown socket command sometimes appear because of "auto-sensing" of old OSCam version. Please contact @MegaV0lt, he is currently successfully testing my patches, this could help in your case. Anyway - closing the issue as I am unable to catch this problem in such a rare reveals.
