That is very unexpected.

Related to me not having a subscription for these channels (no descrambling and then timeshifting stops)?

Can you reproduce the crash if you scan only 682 MHz with the original TsWriter?

Yes. Logs attached

Scanning doesn't require a subscription.

Scanning doesn't require a subscription.

OK. Anything else you need?

@HomeY
Apologies for the delayed response.

OK. Anything else you need?

In short, the answer is that the only thing that would help is a dump that I can use to reproduce the crash. I expect/expected a bigger dump would help with this. It puzzles me that the larger SDT/VCT timeout is not producing a bigger dump... so I'm not really sure where to go from here. I guess it would help to double check the setting is correctly applied.

If you can't get a bigger dump then then only thing I can think of is to use trial and error to find the crash source. We'd do by testing with successive TsWriter builds which disable certain parsers or parser sections until we find the source of the problem. This could be quite time consuming for both of us, but most likely we would eventually find the cause.
Are you willing and able to go down this path?

Hi,

Is it possible to dump with TVE3 and/or with DVBViewer tool, i don't remember the name but i think it can dump something (not sure @ 100% lol)

Is it possible to dump with TVE3 and/or with DVBViewer tool,

Yes and yes.
Problem is:
1. My internet cap is 10 GB per month, so I can't afford to be downloading 200+ MB TS dumps.
2. HomeY said he'd never created a TS dump before, so best to keep the process simple.

i don't remember the name but i think it can dump something

It is called TransEdit.

 

[Sebastiii]

Great
So best way would be to take remote control for a quick test
Better to build you current branch for testing ?
Or better to ask when branch is based on to make it debug more easy

In short, the answer is that the only thing that would help is a dump that I can use to reproduce the crash.

That i understand I've given it another go and just to make sure i didn't miss anything, i'll sum up the results here:

Using your modified TsWriter file:
Triple checked the SDT/VCT setting and it's set to 60 seconds.
Started a manual channel scan on the 682000 frequency, which just ends after little less than 20 seconds, with the attached dump as result.
So that still ends 'premature'.


Creating TsDump with TVE3.5:
Stopped MP2 Server, restored original TsWriter.ax and started MP2 Server again.
Started SetupTV and enabled both the dump option under 'Debug Options', left the SDT/VCT to 60 and restarted MP2 Server again.
Manually added a channel from Transponder 7 (AljazeeraEnglish in this testcase)
All channels on this transponder
Configuration of channel

Started Timeshifting, but there is no rawpaketdump.ts created.


Creating TsDump with TVE3:
Started SetupTV and enabled the 'Dump raw TS' option. Restarted the TV Service (from manual control) after enabling this.
SDT/VCT here also set to 60 secs just to be sure.
Went into Manual Control, selected the 'Ajazeera English' channel and hit 'Start TimeShift'.
Here again, there is now rawpaketdump.ts created.


No clue why i don't get the tsdumps, maybe related to my OS (Server 2012 R2)?

Are you willing and able to go down this path?

If that's the only way to get this fix, then let's do it, although i can understand that there are more important things to get fixed first. I can work around this problem by simply skipping scanning on this transponder/frequency. It seems to be the only frequency that causes issues, and i don't have a subscription for those channels, so i'm not missing out on anything.

If TransEdit is another way to get a dump for you, then i can have a look at that also, and Seb can probably help me with that also.

I think CAM return that it can't decrypt the stream, so the dump is too short.
I'm not 100% sure but will try to see how get a dump with transedit (refreshing memory lol)

I think CAM return that it can't decrypt the stream, so the dump is too short.

But mm stated a subscription isn't needed for scanning:

Scanning doesn't require a subscription.

But let's see if we can get a dump with TransEdit
