Is anyone familiar with the protocol used by IBM "videocharger"
servers? There's a great deal of video material online at
www.researchchannel.org which I'd like to be able to obtain in high
quality form. Low quality streams are available as wmv1 via normal
http, but the high quality 5.6 mbit mpeg2 streams use some lame ibm
"videocharger" protocol. I grabbed:
http://vc-win-1.cac.washington.edu/lantv/cgi-bin/iscpfsel.exe?asset=uva_nplc9_dalai_m2_56m_mpg
and obtained the following:
[ivs_session_begin]
version=3
passticket=1000
protocol=1
serveraddr=140.142.8.90:8500
codepage=1
numberstreams=1
sessiontype=1
dataprotocol=3
sourceaddr=0.0.0.0:0
[ivs_session_end]
[ivs_stream_begin]
title=uva_nplc9_dalai_m2_56m_mpg
longname=uva_nplc9_dalai_m2_56m_mpg
length=4544
mediatype=33554433
bitrate=5600000
autoplay=1
invalidcommands=0
filesize64=0,3180834820
[ivs_stream_end]
It looks like it should be pretty straightforward, but I don't know
how to make a request to the server at 140.142.8.90:8500. It doesn't
seem to speak anything like http, at least.
Has anyone encountered this mess before? Are there any tools available
already?
