blind-next-frame - Extracts the next frame from a video
blind-next-frame [-f frames] width height pixel-format ...
blind-next-frame reads the first frame available in stdin, and prints it, with a head, to stdout. No excess bytes are read, and blind-next-frame can be used again to extract the next next frame. The width, height, and pixel format of the video must be specified with width, height, and pixel-format, respectively; blind-read-frame(1) is used to extract this information. And argument following pixel-format is appended to pixel-format with <space> in between.
-f frames
Read and output the first frames frames rather than the first single frame.
