I would like to ask a quick question to the VLC experts on this
Suppose we have a video mcast stream over UDP coming in to a laptop
running VLC. Let's assume the laptop is running Windows XP.
When the stream comprises IP packets A, B, C, D, E, F....
the video shows fine on VLC.
What would happen when
A)the stream is A, A, B, B, C, C, E, E, F, F...
- every packet is duplicated at the IP level - same IP pkt header
and payload On every duplicate
B) the stream is A, B, C, A, D, E, F, B,C, G
- every packet is duplicated at the IP level, but don't
necessarily arrive back to back
C) the stream is A, B, C, A, D, E, F,
- an occasional packet is duplicated at the IP level
What I'm trying to understand is whether VLC can detect and weed out
duplicates. If someone could explain, exactly how VLC deals with
cuplicates, that'd be great.
