ola,
In the meantime, I've dropped my search for pdp_ffmpeg~ and switched to trying
pdp_theonice~
nice decision. note, it will only be useful if you connect to an icecast > 2.2... or one from : http://mediacast1.com/~karl/
However, I run into the same problem: pd can't create it, along with several
other objects, including
pdp_charcoal, pdp_i (but pdp_o is okay) and pdp_icedthe~
pdp_theonice~ and pdp_icedthe~ are available from PiDiP 0.12.18 on... so that's normal you don't have them in 0.12.17.
pdp_charcoal is an abstraction, so you must lack the path to where the abstraction is. you can use the -path option from pd to set it right.
concerning pdp_i, i don't understand, should be there along with pdp_o, the help patch id called help-pdp_streaming.pd.
suerte, sevy
