Rotate of videos without recompression

[Terka]

Hi, not sure if this is the correct subforum i should post.
Is there any program to set video orientation without recompression?

ffmpeg can write rotation metadata into mp4 containers. But not every player supports this.

ffmpeg -i "input" -metadata:s:v:0 rotate=90 -c copy "output.mp4"
