[FFmpeg-user] Exactly one WebVTT stream is needed

Sun Nov 22 18:04:49 CET 2015

what is wrong on the Command Line ?
In ffmpeg 2.7.2 it runs without any Problems, the Problems first started
with ffmpeg 2.8.x.

I want to convert completly a Multicast Stream into HLS Format, with all
Streams, including subtitle Streams.
Subtitle Stream is also needed as is.
So it's a simple Conversion, and no reencoding of any Stream.
