Descrambling stops when audio track is removed from broadcast #251
Comments
Hello
It looks like an issue on the client side that does not see the new stream.
As you said it is fixed by a manual zap, meaning the new descrambled flux
is sent (as MuMuDVB have no information about zaps).
VLC have a code that is more tolerant to bad streams, so it might be that
oscam sends something weird during the transition or that the MuMuDVB
rewrites are messing up a bit.
I would try to disable the PMT/SDT rewrite and see if it changes anything.

programming. Once the change occurs the MPEG-TS will remain encrypted until
Track 2 is enabled again in the stream or a manual channel zap. MumuDVB
reports no errors or warnings and OSCam only reports this in its log.

My config file for MumuDVB:
freq=11758.50
pol=h
srate=27500
delivery_system=DVBS2
card=0
dvr_thread=1
scam_support=1
multicast_ipv4=0
unicast=1
port_http=100
autoconfiguration=full
autoconf_sid_list=139
I have extracted part of the MPEG-TS where this track change occurs to
help illustrate the problem. At 0:08 the stream will become encrypted and
available audio tracks will change from 2 to 1. VLC is the only media
player I've found that will play and show this correctly.

Hi, Is there any specific command I need to put into the channel config? I've tried rewrite_sdt=0 and rewrite_pat=0 but neither made a difference. Will autoconfiguration=full override these and default them to 1? |
Cleaning old issues
it does override but the arguments are processed in order
