[Libav-user] rtsp base64 encoded credentials

Hi all,

I've done a little more digging with a bug which I believe must be quite 
common, string parsing at "av_url_split" for authentication extraction.
The issue exists in v4.2.2.

line 4817 - libavformat/utils.c 

ls = p + strcspn(p, "/?#");

This does not permitĀ  passwords or user names with the characters:

Can anyone confirm this to be the case or not please.
