Description

Hello!!

I am facing a strange problem with transcoding livestream DVB Stream.
On some channels i have zapping times of 15seconds+.
The tvheadend instance is serving another host through hts where zapping is bellow 3seconds in most cases.(without transcoding of course)

Please see my Log with comments and Config bellow.
I allready upgraded libx265 static in tvheadend with same result. libx264 is behaving the same way = big zapping times.

(I think)® that the stream is passed to fast to transcoder. maybe add an "delay option" into streaming/profile section?
I do not have the skills in coding to do this on my own. But i can build from git and test changes if someone can add a feature like this to git repo.

This is where the bunny lies in between the pepper ;)

Thanks!
