How can I make SDL output displaying with audio stream in ffmpeg?

Question

Learning ffmpeg, I tested SDL output by the code below. I noticed that video played well but no audio.

ffmpeg -re -i INPUT -vcodec rawvideo -pix_fmt yuv420p -window_size qcif -f sdl "sdl out"

there was no sound. audio stream was not appeared in the sdl output, but only the video stream.

How can I make sdl output take audio stream as well as video stream? thank you

Not possible. The SDL audio muxer is only implemented in ffplay.

So can you explain this answer? Does the command work? Comparing it to what the original poster has posted it seems like your command adds `-f pulse "pulse out"` to the end of the command. Can you explain why that would work here? – Giacomo1968 Jan 06 '21 at 02:56
