Is it possible to extract the audio from a video directly to stdout

[ahmetb]

I am looking for something that downloads the video to memory (or a temporary place) and streams the extracted audio directly to standard output as it is converted.

So something like:

youtube-dl -x -o - http://url

however it gives me error:

youtube-dl: error: Cannot download a video and extract audio into the same file! Use "-.%(ext)s" instead of "-" as the output template

If there are any workarounds to this, I'd appreciate. My use case is, I'm trying to extract audio of a video to stdout in a single command (say, docker container entrypoint) .
