what are you asking?

if you can stream a random avi? this question is not ffmpeg related, the
awnser in practice depends on the avi, the encoder settings the video your
network bandwidth and many others, see video buffer verifer (google maybe)
if you want to know how to ensure that things can be streamed
without running out of bits at random

the only ffmpeg related question here seems to be if you can play a partially
downloaded avi assuming that the part you want to play is already downloaded
the awnser is of course yes
