If i switch from channel A (tv-card 1) to channel B (tv-card 2), the tv becomes deactivated on clientside (if in tvfullscreen, mp switches back to tvhome automatically and "TV on" turns off). This is caused by an IndexOutOfBoundsException in TVHome.cs at line 1331 (ViewChannelAndCheck-method) that occours only on non-singleseat-enviroments:

        if (IsSingleSeat())
        {
          g_Player.CurrentAudioStream = prefLangId;
        }
        else
        {
          IAudioStream[] streams = TVHome.Card.AvailableAudioStreams;
          TVHome.Card.AudioStream = streams[prefLangId];
        }

TVHome.Card.AvailableAudioStreams returns an emtpy array (no audiostreams available - timing-problem?), so that prefLangId (index) is out of bounds every time. The problem occours only, if the tvserver has to change the tvcard to tune the new channel.

I think this might be related to this bug report here-

I hope it gets commited to SVN

whooops - you are right.... at least something is happening

 

[gibman]

the "AvailableAudioStreams" method for DVB cards are lcoated in ...

"tvcarddvbbase.cs" in the tvlibrary assembly.

public List<IAudioStream> AvailableAudioStreams
    {
      get
      {
        if (_mapSubChannels.Count > 0)
        {
          return _mapSubChannels[0].AvailableAudioStreams;
        }
        return new List<IAudioStream>();
      }
    }

I have a feeling that " _mapSubChannels.Count" is 0, so the method will return a new empty array (new List<IAudioStream>()).

Now we have to find out why _mapSubChannels.count is 0.
If that is the problem that is.

I have found and corrected the problem

I will submit a patch file for one of the devs.

Stay tuned.

Hello,

Many thanks for this - i will have a look on it tonight.

 

[gibman]

No problem

Please let me know of the outcome.

Also the the exception u mentioned about "AvailableAudioStreams" was a bi-problem of the timeshifting being stopped.

So this error should be gone also.

Recompiled the tvplugin with your diffs...
works very well now! device-changing while channel-switch not longer results in an exception/disabled TV. Many, many thanks for this
