mpg123 works well for icecast or shoutcast streams - curl to help it play https

mpg123 http://stream.sssmediacentre.org:8000

works well on raspberry pi, even doing retries so that playout resumes after short network outages, unlike browsers like Chrome or Firefox. The buffer is also a minute long, so that short outages of a few seconds are not noticed as gaps in audio.

But mpg321, which is the package which supports mpg123 now, does not seem to have support for https. With the help of curl as mentioned here,

~$ mkfifo pipe
~$ curl -L https://stream.sssmediacentre.org:8443/bhajan -o pipe & mpg123 pipe

Works well.
