Error "ECM - key late"
0%
Description
I use TVheadend version 4.1-2216~gfd7806a-dirty and Oscam version "1.20-unstable_svn Build: r0 Compiler: arm-mv5sft-linux-gnueabi"
on TBS MOI+ IPTV streamer. My MOI+ has dual TBS 6281 DVB-C card and TBS 3102 card reader.
ISSUE:
occasionally (once every few hours) scrambled channel freeze.
The log appears the error "ECM - key late" of the large late time.
It helps to temporarily switch to another channel.
I attach the debug log from TVHeadend, Oscam and CA Configuration in the screenshot.

Provide the full oscam log for 'dvbapi' (debug level 128) for oscam and enable '--trace descrambler,capmt' in tvh. https://tvheadend.org/projects/tvheadend/wiki/Traces

OK, but I have problem with '--trace descrambler,capmt' option in my tvheadend. This option is totally ignored in startup script or web interface. Works only 'all' parameter, but this produce probably a GBits log after a few hours...

I have 11GB log - '-- debug all --trace all' after 10 night hours. The error "ECM late" occurred after 4 hours...
I have no idea what to do with this file.

- File oscam.zip oscam.zip added
- File tvheadend.zip tvheadend.zip added
OK, attached tvheadend.log cut with scripts:
- the occurrence of the ECM error
- removed from the lines included TRACE: tbl-eit, timeshift, parser, tsfix, htsp-sub, upnp, tbl-base
Additionally full oscam.log with debug level 128.

An answer? Plan? Something I can complement? Problems constantly repeated ...

Could you try to add your CAID (0B00) to "const_cw" section in data/conf/descrambler ?
Updated by Mariusz Ch. over 9 years ago
I added this section:
{
"name" : "Stansat",
"caid" : "0B00"
}
I'll come back with the observations

The error "descrambler: ECM - key late" still occurs.
Updated by Jaroslav Kysela over 9 years ago
It's very unlikely. Do you see "adding CAID 0B00 as constant crypto-word" line when you start tvh? Also, provide another traces.
Updated by Mariusz Ch. over 9 years ago
I'm not sure what you're asking. I changed file /tvheadend/data/conf/descrambler adding the section:
{
"name" : "Stansat",
"caid" : "0B00"
}
then restart tvheadend done. What more can I do?
Updated by Mariusz Ch. over 9 years ago
but I had something else earlier in this section and added a new entry as the second. Is that good?

Check tvh log for line in comment 9 .
Updated by Mariusz Ch. over 9 years ago
OK, I understand now.
After allowing only one entry in the "const_cw" section of descrambler file, tvheadend starts with "adding CAID 0B00 as constant crypto-word" option and the ECM key too late problem is resolved.
I have another question what are the options "adding CAID XXXX as quick ECM"?

Hi,
I have same problem with ECM too late with another caid, when add to "const_cw" section in data/conf/descrambler problem resolved, but my question is to every problematic caid i must add and every new version i must add my problematic caid, can make something to maid code and not make this on every new version ?
Thanks
