There are several video players, such as SMPlayer, that support rotating 90 degrees clockwise or counterclockwise during video playback.

If you don’t have FFmpeg, install it first. FFmpeg is a large suite of libraries and programs for working with multimedia files and streams.

In the command, “transpose=1Is also as follows.

  • 0 – means rotate 90 degrees counterclockwise and flip
  • 1 – means rotate 90 degrees clockwise

In my case, the command is:

ffmpeg -i ~/Videos/aisha.mp4 -vf "transpose=1" ~/Videos/aisha-rotated.mp4
