Stream ouput in python using vlc
Posted: 11 Apr 2009 21:29
I want to create a python script that takes a stream from a unique ip and streams it to multiple others. I've built the vlc.so file and succesfully imported it. I used the sample code from videolan site :
The script runs with no errors and if I use a stream ip as a parameter it actually does half the job (it takes a stream as an input). The problem is that
I don't want a window at all (So gtk stuff is not needed) but I just want the script to create an other stream as ouput. The concept is this :
"original stream" ----> python script ------> "new stream (multiple addresses)". I know this is possible using the ui so I think there must be a way to do the same using the library. Anyone?
