rtsp and vlc

Hi, I’m trying evostream in rtsp mode. I put a file into /var/evostreamms/media, and manage to see it with vlc: rtsp://172.16.215.2:5544/vod/mp4:mymovie.mp4 (in fact I tried with several videos and get the same behaviour) 1/ some lag/frame drop with VLC But I have something odd: with vlc, it is lagging a bit at the beginning of the movie (let’s say the first 20% of the movie). After that, it works better and smoothly. I don’t have the same behaviour when the movie is served with wowza (where I use url rtsp://172.16.215.2:1935/vod/_definst_/mp4:mymovie.mp4), or the problem is smaller and I don’t see it. I checked with wireshark, both communicate in RTSP. 2/ filesize Also, when I use VLC or Wowza, I don’t get the same initial size (inital size=24M, what I get~=15M in both case) – with Wowza: 15730317 bytes – with evostreamer: 15724081 bytes Ok I have a 6k difference, not a big deal, so frames should not have been dropped (I guess) 3/ with android: ok When I use some android devices, I don’t have the lagging problem. Ok, the problem is mainly with VLC, and our target is more android devices, but I was wondering why such (small) differences. Can it be my video, which is not in a standard profile or not well encoded? Thanks Nicolas Zin
