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
<https://github.com/FFmpeg/FFmpeg/commit/554576b6cfe79a91d37e14d3617ca417562085db#diff-b45fad75a4dfb82ef50e978d38dc2649>
ls = p + strcspn(p, "/?#");
This does not permit passwords or user names with the characters:
"/?#"
Can anyone confirm this to be the case or not please.
example:
"rtsp://admin:bob#[email protected]:544/27f255e7-07be-38b7-83a3-fec9072713de"
last commit (however always perhaps broken)

Cheers.
Rich.

Hi,
I'm looking at a way to use a base64 digest string as input into the
"avformat_open_input" call for the credentials portion.
Sure that you would normally use:
rtsp://user:[email protected]/live/ch00_0
format as an example, however, this format does not account for
invalid characters that are valid password characters, examples:
@password
password/\""
password/""password/""
password""password""
Perhaps a method exists that I'm unaware of, any ideas welcome.
Cheers,
Rich.
