[libannodex-dev] Where I am at

Thu Mar 31 07:12:38 EST 2005

Dear Colum,

I just realised that we have a very very old webpage up there and the content is way out of date. I will fix that webpage, but it also requires some content updates.

In the meantime, please use: http://media.annodex.net/aida/movies_this_week/index.anx for your test. This one has a nice low bitrate, too. It is copyrighted by AAP, so don't redistribute it and delete it after your testing.

Cheers,
Silvia.

Hi All,
I am trying to install the apache module, I think I have the webserver running because its automatically picking up the afeview when you feed it a .anx file however we have tried copying the .anx files from your test content (the Research Hunter which I renamed to conrad.anx) but they dont seem to work the same way, specifically only the first keyframe appears and the start time is shown as NaN:NaN:NaN. When I view the command-line output from Firefox when I do this shows 'no suitable access module for ......' but that's the same thing I get when viewing your test content on your site, 
so I'm guessing that it's related to the mpeg encoder not being present.
Any ideas?
Colum

Hi Conrad,
Heres where I am at the moment.
I have the plugin working for Firefox because I can view the test content on 
your site.
I think I have the webserver running because its automatically picking up 
the afeview when you feed it a .anx file however
we have tried copying the .anx files from your test content (the Research 
Hunter which I renamed to conrad.anx) but they dont seem to work the same 
way, specifically only the
first keyframe appears and the start time is shown as NaN:NaN:NaN. When I 
view the command-line output from Firefox when I do this shows 'no suitable 
access module for ......'
but that's the same thing I get when viewing your test content on your site, 
so I'm guessing that it's related to the mpeg encoder not being present. So 
I have downloaded the source files
(index.mpeg and index.cmml) and have tried to convert the mpeg into an ogg 
file (using ffmpeg2theora). Then when I try and create a .anx file using 
anxenc I get a 'Segmentation Error'.
I realise these are all probably seperate issues but any help you can give 
would be appreciated. I have followed the instructions in your previous mail 
so I should be up to date on all the libraries.
Thanks again for your help.
Colum
