Pipe entry in ffmpeg

Question

I am trying to use ffmpeg to decode audio data. Although it works to load from a file, I would like to avoid using files because I would like to use a temporary one for this. Instead, I would like to pass the data (which I previously uploaded) using stdin.

Is it possible?

eg.

• Manually upload mp3 file
• Connect it to the process created by ffmpeg.
• Get the original output

(it should also work with ffprobe and ffplay)

Answer 1

ffmpeg has a special pipe flag that instructs the program to consume stdin. note that usually the input format should be specified explicitly.

Example

( 16- PCM):

cat file.mp3 | ffmpeg -f mp3 -i pipe: -c:a pcm_s16le -f s16le pipe:
