Description

As first descrambling in general works while streaming two channels at a time. But I recognize one curiosity for only two channels.

Setup is:

Two VLC-players

- First player I switch to "Sky Cinema Bourne HD". Ok...
- Second player I switch to "Sky Cinema Action HD". Nothing...
- First player I stoped watching.
- Second player stream starts.

Tried different channels all works fine. Only these two channels do not work at a time.

Mister Pablo Rodríguez - I'm currently on latest "4.3-156~g85ea455ba-dirty"
@Petar Ivanov - On another setup with Astra I also can't reproduce this... It's just on the Cable setup...

In service details for the cable setup the video pid for these both channels are identical:

Sky Cinema Bourne HD    0x02ff /   767    H264
  Sky Cinema Action HD    0x02ff /   767    H264

On the astra setup video pid's differs

This is really insteresting. It appears that the video stream is not scrambled - two services share this and both have different keys (and different key updates).

So I mean the uniq way to different them is with his name. Who should go with ca request.

The problem is more deep. Oscam sends keys back only with pid for the first elementary stream (which is video pid in most cases). As you can see in tvh log, both services are descrambled using same key from the first subscribed service. It appears that we need a modification in the dvbapi protocol to handle this special issue.
