For each frame I want to crop multiple areas using ffmpeg but I am not sure how to proceed.
This is what I have done to crop one part of the image,
fmpeg -i video.mp4 -filter:v "fps=1,crop=759:41:33:99,scale=128:44" %d.png
This is one frame of the video,
The above command crops the number one row or first position from the image. Likewise I want to crop all the positions or rows from this frame.
Add more outputs.
ffmpeg -i video.mp4 -filter:v "fps=1,crop=759:41:33:99,scale=128:44" row1-%d.png -filter:v "fps=1,crop=759:41:33:140,scale=128:44" row2-%d.png -filter:v "fps=1,crop=759:41:33:181,scale=128:44" row3-%d.png
Or do one row per command.
