print rtmpdump command to stdout?

[wyatt8740]

Sorry if this is a dumb question, but I'm wondering if youtube-dl uses rtmpdump or librtmp. if it uses rtmpdump, could there be a way to make it print the arguments it uses to stdout? I'd like to use rtmpdump and pipe it directly into ffplay, and youtube-dl makes finding the necessary information for invoking rtmpdump so much easier.

We're using rtmpdump. Add -v/--verbose to see the command-line arguments:

$ youtube-dl -v http://www.roxwel.com/player/passionpittakeawalklive.html

Note that you can simply pipe the output of youtube-dl ... -o - to ffplay.
