Autoresolution detects wrong frame rate

14 May 2014 - 20:40

Hi,

 

i am using OpenPLI 4.0 (last updated today) and i found the following bug:

 

While playing some MKV files, autoresolution detects the wrong frame rate of 23.976 fps (Original frame rate in mediainfo) instead of fps Hz (Frame rate in mediainfo). This results in a stutter once per second.

This file plays fine when AutoResolution is disabled and TV stays at 50 Hz (multiple of 25).

 

Why does AutoResolution (using iServiceInformation of enigma) retrieve the wrong (original) frame rate? I think this should be fixed.
