HEVC encoding/output support

[Premicheal]

Is it possible to support HEVC as a output type for transcoded or atleast remuxed media. My hw cannot handle video encoding, therefore I use jellyfin with only direct stream and audio transcoding enabled. This allows me to play my entire library on my TV without any issues on the jellyfin webpage/app. Streamio however only direct plays h264. All H265/HEVC always undergoes transcoding. On manually disabling a few settings in the compiled code, some h265 videos are directly playable on the streamio-shell. But still I could only get roughly 40% of my library working this way. (some h264 stopped working, probably the ones which needed remuxing) Is there anyway to support this jellyfin setting, since we already use fmp4.

Prefer to use fMP4 as the default container for HLS, making it possible to direct stream HEVC content on supported devices.
