# command: ffmpeg -i input -vf transpose=2 output New_path = os.path.splitext(file_path) + '_rotated_90' + ext
Movie_files = įile_path = os.path.join(folder_movies,i) Import subprocess # import subprocess moduleįolder_movies = '/home/user/Desktop/test/'
Your movie extension: import os # import os module You only have to edit folder_movies path, path_to_ffmpeg and set To Batch process a folder of movies you can use a programming language of your choice and iterate through the files. So you will not see just how much of each of your video is done.īased on this answer you can use ffmpeg with following commands to rotate a video: ffmpeg -i input -vf transpose=2 output Please keep in mind that no output will be given until each encoding completes. One way to start all these jobs would be: parallel avconv -i ".mp4" ::: *.mp4 I will not write about all the features of this tool, but will concentrate on your specific task. What you should be doing for such a job is using parallel, a tool that allows you to start several jobs at once, and it can do everything that a for-loop can, but better. You have specified that you are interested in working on a huge number of videos, if you have a multicore machine and you will use a normal for loop provided by your shell, you will have one of your cores running hot, while others are doing absolutely nothing.
