[FFmpeg-user] Can the video orientation be adjusted for part of an Mp4 ?

[Peter]

Hi,

We have a video that was taken from a mobile phone. The first part of the video 
is not orientated properly, and needs to be moved anti-clockwise 90 degress.

At approximately 4:30 , the video orientation is corrected.

Is there a method with ffmpeg to adjust the video orientation for the first 
4:40 minutes ?

Here is the video details:
