ffmpeg extract lossless image from video
I have a 5s fps25 mp4 video and I use the following command to extract jpg images from the video
ffmpeg -i input.mp4 -r 1 -q:v 1 output_%01d.jpg
The images are extracted successfully, but jpg files quality isn't good enough.
How can I extract better quality images?

Try
ffmpeg -i input.mp4 -r 1 -q:v 1 -qmin 1 -qmax 1 output_%01d.jpg
If not good enough, use
ffmpeg -i input.mp4 -r 1 output_%01d.bmp
and use another JPEG encoder.
