Congratulations on your success in downloading an RTMPE stream using
RTMPdump v2.1d, running a non-English O/S.
Sadly, I haven't been able to duplicate your results with ITV Player.
To assist other users, please could you clarify -
a. Which operating system you are using.
b. Which language version of the O/S you are running.
c. Which country you are in.
What you've achieved seems to be not possible for users within the UK, using v2.1d of RTMPDump under Windows 7, if running an unmodified (i.e. English) version of Windows 7.
The Windows 7 system which I've been testing failed to connect to ITV Player's RTMPE stream even when running RTMPDump v2.3, but succeeded when running RTMPDump v2.4.
I would much prefer to be able to use RTMPDump v2.1d as that would enable it to run even on my home computer, which uses Windows 98SE.
