Hello emby team,
Thank you so much for an awesome product. I left Plex a few years ago and have never looked back again.
My main clients until rather recently have been x2 Minix Android devices running Emby for Android TV. These have been playing all of my content (besides H264 High 10) without any need for transcoding of the video stream. However since I swapped them out for Apple TV units it seems that all of my media requires transcoding.
My initial concern regarding this was my h265 content but unless I am reading the logs incorrectly it would seem that even h264 content is being run through ffmpeg. In the H264 sample I've attached, the subtitle is not supported by the apple TV unit but it would seem that in addition to this the server is recoding the video stream as well?
Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264))
Stream #0:1 -> #0:1 (copy)
Also for your information. Regarding the h265 content, I have run some tests with ffmpeg rewriting the tag with "-tag:v hvc1". This has allowed me to stream the files through iTunes (In mp4 format).
Server & Client versions
Server: Debian 3.16.51-3+deb8u1
Client: Apple TV 4K - tvOS 11.2.5
Thank you for any assistance you can provide!
