	/*
	* To get the desired bug, compile ffmpeg with mbedtls support.
	*
	* This will loop until either no more fd can be opened, or an error happens when trying to open the url.
	*
	* Check the value fd after each time avformat_open_input is called.
	* Try this with a http / local file and you will notice that fd will keep the vallue of 3 (0=stdin, 1=stout, 2=stderr)
