I have tried multiple apps: kodi, vlc, mx player but H.265 either stutters or crashes the app. Any insight on wether the new Google Tv supports HEVC? Or which codecs it does support?
SOLUTION: So turns out in kodi I had audio passthrough enabled and DTS was enabled. Which I had to disable. It was causing my issues. Out of luck it seems I was streaming all DTS audio files. Dolby digital and dolby digital plus files work fine with audio passthrough. But not DTS. Hopefully this helps others. H.265 4k works just fine now.
Yes it supports HEVC, that’s what 99% of streaming services encode their 4K video in. What is the bitrate of the file you are trying to play? Is you Chromecast connected to WiFi, or are you using an Ethernet adapter?
