I see lots of examples using FFMpeg to make a video file from a set of images. I can also see how to do the opposite if I want individual files. However, I want the images to be pushed to stdout. This line fails:
ffmpeg -hwaccel auto -i Wildlife.wmv -pix_fmt bgr24 -an -sn -f bmp - > junk.bin
It says "Requested output format 'bmp' is not a suitable output format". However, this line works fine to generate image files:
ffmpeg -hwaccel auto -i Wildlife.wmv -pix_fmt bgr24 -an -sn test%03d.bmp
How can I get images pushed to stdout?
