L.s.,
I tryed to show the video Editie_NL_RTL4.m4v on the website www.janvanegmond.nl with the plugin Allvideos. Therefore I used the format {m4v}Editie_NL_RTL4{/m4v}. In the configuration I set the local video folder to 'images/videos', the folder where the video is stored.
You see my effort on the page www.janvanegmond.nl/index.php/dinitrol-antiroest at the bottom of the page. The nextr message is shown:
The video could not be loaded, either because the server or
network failed or because the fomat is not supported:
wwwjanvanegmond.nl/images/videos
/Editie_NL_RTL4_m4vundefinedundefinedundefinedundefinedu
What did I done wrong?
Sorry for my bad English, my Dutch is better  :).
With kind regards,

Your web server should be configured to serve mp4, ogg and webm mime types:
.mp4 - video/mp4
.ogg - video/ogv
.webm - video/webm

If you are running Apache:
You can add the mime types to your Apache webserver configuration httpd.conf
However if you do not have access to your webserver configuration files (for example, if you are using a shared hosting service) then you need to place a .htaccess file in your video folder and add following to it:

AddType audio/ogg .oga
AddType video/ogg .ogv .ogg
AddType video/webm .webm
AddType video/mp4 .mp4

For httpd.conf and .htaccess files you can place this information at the end of the file.  If you do not have an .htaccess file you can just create a blank file and add this information (no other information is required).

Hi,

Thanks for your quick reply!

I put a .htaccess file in de folder /images/videos which the following information:
AddType audio/ogg .oga
AddType video/ogg .ogv .ogg
AddType video/webm .webm
AddType video/mp4 .mp4
And..... I get the same error as before. forum.joomlaworks.net/Smileys/joomlaworks/sad.gif
