[Rejected] Patch to fix "No PMT" or "PMT Timout" errors (1 Viewer)

[nealeb]

Tried the SVN with the "PMT timeout" patch, and it seems to work for me. Had it running a couple of days and haven't missed a channel change yet. Unfortunately I have other problems with this version (mainly that it will not set a wakeup for recording) which means that I can't leave it running as my main PVR but it's looking good for the PMT problem. That's with DVB-T.

For me, not working on all channels

I mean i'm not using patch. I'm using versions that are in svn.

With svn 23652 tuning works okay.
With svn 23670(latest so far) not working with canal digital Canal+ Action


Logs attached.

without the tswriter.log I can't see anything.

the current version (svn 23667) does look for both the requested PMT pid and ServiceID, and returns PMT if it matches the ServiceID

btw: did you use the recent tswriter.ax and run regsvr32 before?

 

[te3hpurp]

here they come.

Here are tswriter logs.

ok the issue comes from section decoder:

22-09-2009 14:40:02.507 !!! CSectionDecoder::OnTsPacket Entered infinite loop. pid: 2A4 start: 90 BufferPos: 5 SectionLength: 2 - Discarding section and moving to next packet
22-09-2009 14:40:04.319 !!! CSectionDecoder::OnTsPacket Entered infinite loop. pid: 29B start: 148 BufferPos: 7 SectionLength: 4 - Discarding section and moving to next packet

a) are you able to reproduce this issue?
b) can you revert ONLY tswriter.ax to svn 23648 and re-test???

 

[te3hpurp]

a) Yes.
b) I'll do that in the evening and post log early tomorrow. as 23652 is now working somewhat ok and family need tv .

Is there specific reason for 23648 of tswriter, because logs allready from 23652 are same because tswriter is same:
From svn logs we see that last time it changed was 23648 before this, and 23652 contains same as 23648

Now we find the pmt and also update the database with the new details.

23648 tswriter log

here is log from 23648 svn of tswriter.ax used.

everything is okay with this version.

 

[morpheus_xx]

can you try the attached tswriter. it's the same as in svn, but adds a bit more logging

 

[te3hpurp]

With attached tswriter, not working.

Log included.

svn current version 23677 does 2 different ways:

1. Work as before, look for the requested PMT. If it times out once, it sets PID to 0 to allow tswriter to look up PMT from PAT for given service
2. by creating a file "c:\usePATLookup.txt", it always tries to lookup PMT from PAT.


if you're using default (1) way, when another PMT pid is seen, DB is still updated.
if you're using new (2) way, it doesn't care to change DB, because service id is the primary key then
