Shall fix issue Live TV - Captions not available (nor audio tracks) #63

Applied this to current master.

Subtitles:

Works perfectly for DVBSUB subtitles. When selecting a DVBTXT subtitle, playback stops with an error: ffmpeg output:

Not yet implemented in FFmpeg, patches welcome

Audio channels:

Switching audio channels does not work reliable. Sometimes it works, sometimes playback continues without video, sometimes without audio, or playback does not continue at all. When stopping playback in Jellyfin Web and selecting another TV channel, the playback issues mentioned above may also happen to the new TV channel, without having touched its audio channel at all.
