[mythtv-users] External Recorder won't change channels

[Marc Rawji]

Hello all,

I am trying to write an "external recorder". I think I have the code
working, for at least one channel.

I can start on one channel, but I don't seem to be able to change channels:
2016-08-01 21:48:24.370456 E  SH(/home/mrawji/recorder/record.sh):
Programmer Error, attempted to add a listener which is already being
listened to.

Mythbackend logs:
<PLAY CHANNEL 2>

For every channel, I recreate a new MPEG-TS using ffmpeg. I am using the
same stream_id for all the channels, since each TS only has a single
program in it. Would that be causing the error?
