1309	Chunked transfer encoding with Live video stream does not clean tmp files	unifiedstreaming@…		"Hi Maxim,

When using 'chunked transfer encoding' Nginx writes the POSTed content to a tmp file (or files).

This will fill up the disk with a large file, but also when a 24/7 Live video stream is sent using chunked transfer encoding. It basically is a a long standing POST where chunks of data are sent within that POST, so the connection is not closed until the stream stops and as it is a 24/7 live linear stream this equals to 'never'.

Nginx therefore cannot be used with a Live when the ingest is handled with a 'request body filter'.

I attach the reference module that shows this behaviour as well as a curl line to do the post.

Kind regards,

Dirk
