Hi
I'm using zm in debian sarge and mozilla browser with vlc plug in for mpeg streams.
the vlc plug in works, mozilla displays mpeg files well.
but when I use zm with mpeg as ZM_STREAM_METHOD mozilla displays a blank screen with "no pictures".
anybody help me
notes:
1- I configure and try zm with ffmeg
2- I have tryed t "mpeg" mpeg4 as ZM_MPEG_LIVE_FORMAT and ZM_MPEG_REPLAY_FORMAT
3- I have tryed zms and nph-zms in ZM_PTH_ZMS

thanks
Palmeira

Have you managed to get images just using the normal jpeg based formats first?

Yes
jpeg as ZM_STREAM_METHOD works. But due to bandwidth reasons I need to use mpeg streams.
thanks

VLC plug -in is from www.vldeolan.org

Can you try a different plugin on your browser and see what happens, perhaps a WMP one from a Windows box? We need to nail down whether the video is not being output or just not being displayed.

if are you specking "windows media player" ? I try to use WMP 9 it with mpeg-2 decoder .
using IE 6.1 with ZM_CAN_STREAM = yes to transfers streaming to WMP.
the result was a black screen .
if you want look my host http://150.164.35.230:8800/zm/index.php

ps
I found a compiler error in Zoneminder 1.22.2.

file zm_mpeg.cpp line 88
AVCodecContext *c = &ost->codec;
cannot convert AVCodecContext * to AVCodecContext **

I'm using ffmeg from cvs : libavcodec version 51.13.0

it means the ZM_FFMPEG_CVS was wrong
I patch it in zm_mpeg.h
with
#define ZM_FFMPEG_CVS 1
#undef ZM_FFMPEG_049

and the compilation was success

Do you for testing? If so then you can possibly try using .swf format which will use a flash player plugin if you have it.
