Describe The Bug When watching movie in browser then CPU loads at high level depending of how many cores (threads in transcoding options) are using.
Media Information Any movie.

All cores:
System (please complete the following information):
For example, Media Player Classic loads CPU in about 1-2%. I assume that Jellyfin high loads CPU because of transcoding. Didn't found how to disable it and use direct play instead.
