[SR-Users] Regex Transformations

[Daniel-Constantin Mierla]

Hello,

the line you try to match is:

m=audio 64192 RTP/AVP 107 0 8 18 101

However, the subst does not have rule to match 'RTP/AVP' string:

{re.subst,/^(.*)m=audio ([0-9]+) ([0-9 ]+)\015\012(.*)$/\3/s}

It is looking for digits and white spaces after m=audio.

Cheers,
Daniel
