I'm currently working on a mjpeg proxy server with aiohttp. I use the StreamWriter to transmit the information. But if I'm using

sr.write(b"x")
sr.write(b"y")
sr.write(b"z")

the StreamResponse appends the length of the chunk with a newline

x1\r\ny1\r\nz1\r\n

Is there a posibility to send raw data?

EDIT:

I wrote StreamWriter, but i mean StreamResponse.
I've found out that the StreamResponse uses the chunked transfer encoding and those "not wanted information" are part of it.
