Once again, as soon as I posted below, I seem to have solved my problem, and
again it's much simpler than I'd made it.
I simply made a user variable something like this:
CONTENT_LENGTH ${__BeanShell("v=0${RTSP_PORT}o=- ${SESSION_ID} 0 IN IP4
${HOSTNAME}s=t=0 0a=X-playlist-item: ${PROVIDER_ID} ${ASSET_ID}c=IN IP4
0.0.0.0m=video 0 udp MP2T".length())}
The only issue is whether I need to include the CRLF __javaScript('\r\n') in
the content length calculation. I had to omit it from the above
CONTENT_LENGTH because it seems BeanShell doesn't like having __javaScript()
functions passed into it.
