How to make FFmpeg convert a PNG sequence into a WEBP sequence, instead of making a single animated WEBP
10 août 2022, par nmkdThis command converts a PNG sequence into a JPG sequence :


ffmpeg -i in/%8d.png out/%8d.jpg


However, when using the same command with WEBP :


ffmpeg -i in/%8d.png out/%8d.webp


It will put all frames into a single WEBP, which is animated.


I have not found a way to tell ffmpeg to instead create one WEBP per input PNG.


Is this somehow possible ? I'd like to avoid using any shell scripting/loops.

How to can I redirect the image frames of a video outputted by ffmpeg to a python list in a python script ?
16 novembre 2020, par Ashutosh HollaI am extracting frames from a CCTV video of certain duration using ffmpeg command. The code written in the python script is as follow :


import subprocess as sp

sp.call('ffmpeg -i c21.avi -ss 00:10:00 -to 00:11:00 op2/frame_%1d.jpg', shell=True).



However I want to store every image frames in a python list rather to a file. What are the changes that I need to do ?. I have explored opencv cv2.VideoCapture method which resulted in assertion error after processing certain frames of the video.

ffmpeg -i URL stream.mp4
I know I can use the subprocess command
