At first  problem seems that SDT is not transmitted always below 2s.

 

Here is a "quick" way to monitor how "actual" SDT is transmitted using just dvbsnoop and "(e)grep" command.

 

(first tune to frequency using signal finder)

 

root@osmio4k:~# dvbsnoop 0x11 | egrep "Time|transport stream" | grep "actual" -B1

Last commit by pieterg , increase timeout to 2,5s from 2s.

 

https://github.com/O...16d415ea9718481

 

 

Although looking on the scan code it doesn't seem that problem caused by 2 SDT timeout, due to line "[eDVBScan] got pmt -2" in debug log above.

 

https://github.com/O...b/scan.cpp#L333

 

 

The problem most probably is the other transport stream contains "Transport Stream ID" = 1, same "Transport Stream ID" as the actual transport stream.

I believe that filtering the SDT with Original network Id would work, but that would require first getting the original network id from NIT, prior scanning SDT.

Most probably a guaranteed disaster ....

 

I also believe that using false in eDVBSDTSpec in order to scan only the "actual transport stream" would work, and in most cases would make enigma scanning faster.

 

https://github.com/O...b/scan.cpp#L354

 

Although I am sure that there are "edge?" cases that require scanning the "other transport stream".

 

 

I can't tell what is best solution...

 

It's almost sure, that scanning both actual and other is the best thing.

 

Enigma2 is seems to using a fifo approach. First SDT come, First SDT served.

 

All those years, scanning was "fine", until now.
