I cant do the streaming of video with andre---ibr-dtn2-ibr----carlos.
"carlos" sends the movie to "andre". Carlos have received the bundles but cant see any part of the video streaming.
I've got fragmentation = yes.
What is the problem?
I'm using dtnstream... and ' cant see videostreaming (when i have big files).
