- The video starts at 11:51:03
- The video changes its resolution after 20 secs
- because of buffering kodi detects the change at: 11:51:17

Question is now: why is the Decoder opened at this time (11:51:17)?
And anotherone at (the correct time) 11:51:23

I write this here because I didn't get a smooth resolution change for the video part, also the streams before / after the change fits together, kodi waits for about 0.5 secs before it continues playing it.
Audio works well.

It would be fine If somebody with experience in this could advice me.

Thanks

After some more debugging I found out, that the first open() just reinitializes the Decoder and the 2nd call (caused of a new package) Reopens the Decoder.
So this makes sense and seems to be OK, I'll investigate now, where the syncronization gap comes from.
