linux - ffmpeg to extract a video one frame per second? -

-

currently using command line extract pictures video.

ffmpeg -i ../m.mp4 -f image2 m.mp4-%04d.bmp

this results many frames.

i extract pictures video, 1 frame per second of video. preferably multithreading.

use -r 1 output option:

ffmpeg -i input.mp4 -r 1 %04d.bmp

results in 0001.bmp, 0002.bmp, 0003.bmp, etc.

the bmp encoder has no threading capabilities shown ffmpeg -h encoder=bmp.
