As described in the title, every time I stream a video to my chromecast it works perfectly, until after a minute or 20 it starts to stutter / buffer really badly. Pausing it doesn't help, but stopping the stream and starting it again will enable the chromecast to play again for about 20 minutes.
The issue started about a month ago and during the years before I've never seen this before.
Some more information: I have subtitles enabled, video + audio are direct stream according to the web interface, CPU usage on server is next to nothing. The problem also doesn't occur when playing video in my browser.
Does anybody have any idea what I can do to solve this issue?
