I’m having the same issue, server is on windows 10 machine, has been running solid for years. Galaxy Tab 8.4 anything that requires transcoding won’t start. If I go to the playback settings of the video while the spinning wheel is going and select automatically convert, it plays at 1080p 6 Mbps. If I try to manually set the max quality in the app settings, the ONLY one that works is 720p 2mbps but the picture quality is junk. I have tried every combo of settings in the app.
I feel like the server just isn’t getting the right profile for the android tablets. How do we manually change that? Is there a text file somewhere?
