I decided to install kodi on raspbian stretch yesterday. It seems that I'm not able to play my local library of TV shows. Kodi has issues playing most of them. Especially x264-tbs mkv files, it plays x264.yify mp4 files but it starts green with no audio for a few seconds than plays them. Other than that, if I try to play another video from my local library, it just shows me a dark screen. After installing kodi, are there any other things I need to do? All of those videos are max 1080p resolution.
