Audio data streaming with meta (ICY/Icecast protocol)

[vvvin333]

I am trying to implement audio data live streaming with periodical meta inserted in the stream (ICY/Icecast protocol) using StreamingResponse. But while debugging figured out that amount of raw audio bytes sent and received by client (goal is for AudioPlayer, ICY supported) are different. https://stackoverflow.com/q/79142077/15080117
ICY is rather strict protocol with fixed bytes length (icy-metaint) and after every this block metadata inserted of 0+ length.

I looked at the source code and can see there is {"type": "http.response.body", "body": chunk, "more_body": True} message sent format.
Help me please figure out how can I implement custom StreamingResponse to send only raw bytes (just after the first block with headers)?

StreamingResponse does stream raw bytes chunk encoded. If you want to send them all in one go (not chunk encoded) then you need to send it all at once.

If you can give a MRE where the "amount of raw audio bytes sent and received by client" is different we may be able to help further.

Sure. I'll try to simplify my code and debug with more attention. Maybe I am wrong.

Sorry, I was wrong in my calculation. It is not a problem with starlette
