How to pass image stream to ffmpeg standard input for compression?

Question

bash

There is a fairly simple task for which I can’t think of a solution yet: you need to feed ffmpeg from standard input (via the console pipeline | ) to compress a stream consisting of black and white 8-bit images (the output format will most likely be PGM) . Can anyone suggest a command line example for such a call?

Answer 1

pictures are not a stream, they are separate structures with headers and checksums.
Therefore, they should be submitted as separate files.
What's the problem with setting ffmpeg on files?
