Transcoding problem

I have a problem, sometimes when I read a movie, plex starts to transcode the movie.
It transcodes it from H264 to H264.
The film is in .mkv.
Direct reading and direct broadcasting are well authorized.
I would like to avoid absolutely transcoding.
I get this in the logs file.

There’s a number of technical parameters that influence if a file can be played directly or not.
In your particular case that seems to be related to some of the encoding parameters of the h264 video. The video is encoded using “high” baseline while the player/profile only supports “baseline”.

That’s why your Plex Media Server is transcoding the video – however, because the app itself only shows a simplified version, all you get in the app itself is the information that it’s transcoding from h264 to h264 (when the more conclusive set of information should include it’s h264 (high) to h264 (baseline).

If you want to prevent transcoding at all cost, you’ll need to optimize your media for the devices you’re using.
