Description

Hi,
Situation:
- Streaming service A.
- When subscribing or unsubscribing service B from the same mux as service A, service A stops.

This is annoying because it ruins recording (recording 1 service and zapping on channels from the same mux as the service being recorded).
Only able to test in encrypted channels (dvb-s2).

I have noticed that this issue is random.
Also noticed that the Status page from the webui shows 0 BW usage in the subscription that was ruined, but continues to show BW usage in the "Stream" tab.

Tried with full MUX rx mode and I have the same issue.
Tried 2 different dvb cards and I have the same issue.

Thanks,
lja

Some news:
FTA channels work good.
Only happens if CAPMT is used for descrambling.
CWC works fine.

Priority should be Medium now...

I had the same issue when I tried the master branch a few weeks ago, but in my case I couldn't get CAPMT to work at all so I used the CWC client, and it still failed. Are you sure it's working with CWC for you?

I suspect someone will have to do a bisect to get to the bottom of this, unless someone who knows the code sees this and is able to fix it.

I'm also have problems with empty recorded files (from channels decrypted by CWC client) since my last update to master branch.

I'm using CAPMT (previously had CWC enabled, forgot that was there for previous test, but that's off now) however I've just tried this and couldn't replicate.

I tried:

start service A
start service B
stop service B

and

start service A
start service B
stop service A

in both cases the remaining stream continue to run. All streaming was initiated from the webui and was using CAPMT.

So not quite sure what's going on here.

Luis,

Maybe you could grab a debug log with some trace options enabled:

--trace subscriptions,linuxdvb,dvb,mpegts,cwc,capmt

Might give some indication of what's going on.

Actually, I'm not so sure about thsi now. I had some recordings fail for the first time in ages. And it coincides with both an accidental upgrade of TVH and also my disabling of CWC (so as to use CAPMT only).

I have a problem with empty recorded files on cwc encrypted channels. Even when i'm watching the same channel simultaneously live on tv, the recorded file is empty. In almost any attemp, a recording of the german private pay tv RTL HD fails with no clear indications in the debug log.

Hello,

I have updated to the current latest tvheadend(3.9.542) version and the problem disappeared... so it seems that it is solved...

Problem was presented on 3.9.467

Hello,

Today again the same problem... I have to make some tests... problem could be with tv-tuner driver, CWC/capmnt or tvheadend ...

Hello,

I have tested it all the weekend and found out that the problem is occurring only when I'm using it with capmnt... When I'm using it with CWC it's working fine.... I have tbs6982 dual tuner card with installed official driver from TBS version 140323 and oscam 1.20-unstable_svn,build:r9568 with dvbapi configuration as follow:

[dvbapi]
enabled = 1
au = 1
boxtype = pc
user = tvh
pmt_mode = 4
request_mode = 1

is there something wrong???
