Nothing wrong but note that png is a format that will not work at all if auto-detection fails (there are many formats where forcing the format can be necessary) so in this specific case, the following will always work if the above works: $ ./your_program | ffmpeg -i - ... As an advantage, this may also work if the program sometimes outputs png, sometimes other formats.
