I have Krypton RC installed on my Nexus 7 and it works very well except that any 1080p videos on my LAN will not play. I can only get a still shot on the screen and the timer runs as if the video is playing. All SD and 720p videos on the LAN play fine. Also if I play the same 1080p video using MX Player (over the same LAN and WIFI) it plays fine on this Nexus 7. I do have to set the MX Player to use Software Decoder not the HW decoder.
I am hoping someone knows what the problem is and how to fix it. Failing that is there a way to set MX Player as a default external player? I tried using the Kodi Wiki instructions for setting this up on Android and it doesn’t seem to work. I used the playercorefactory.xml file supplied with the recommended edits. I suspect it will not work with Krypton.
