Cannot seek ogg theora on https (works fine on http)
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; fr; rv:22.214.171.124) Gecko/20100214 Ubuntu/9.10 (karmic) Firefox/3.5.8 Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; fr; rv:126.96.36.199) Gecko/20100214 Ubuntu/9.10 (karmic) Firefox/3.5.8 If I open a ogg theora file in firefox 3.5.8, I can seek it on http, but not on https. I just enter its url in the address bar: http://server/file.ogv : plays and can seek https://server/file.ogv : plays but cannot seek (and total duration is 0) Reproducible: Always

Seeking works for me when seeking over https, e.g. I can seek on https://www.safeshop.co.nz/pearce/video/shuttle-launch.ogg and on http://pearce.org.nz/video/shuttle-launch.ogg Perhaps there's something different between our server configurations? Do you have a specific URL on which you can't seek?
Your links are working fine. But I downloaded the video, and put it on my apache server, it works with http: http://dl.rom1v.com/noindex/shuttle-launch.ogg But on https, I can't seek : https://rom1v.com/shuttle-launch.ogg I don't know what is wrong (the only difference I see is that the certificate is not verified on my server).
It looks like this is happening because the HTTPS connection is serving the file with Content-Encoding: gzip and no Content-Length, so it's not possible for Firefox to compute the correct end location to read to compute the file's duration.
Ah yes, this is effectively a duplicate of bug 489071; Firefox shouldn't send "Accept-Encoding: gzip,deflate".

Sorry, my response could have been clearer. You should probably configure your web server not to compress Ogg video files during transmission. How to do this will depend on your web server, but in most cases there will be a list of files excluded from compression (e.g. JPEG, PNG, ZIP, etc.), and you need to add Ogg to that list.
OK, thank you for your answers. I looked into /etc/apache2/apache2.conf and some other conf files, but I didn't find any list of files excluded from compression. Does anyone know where to configure it?
It depends very much on how your distribution has configured the defaults. Apache 2.x will most likely be using mod_deflate for compression. Looking at an Ubuntu 8.04 VM I have handy, the configuration is in /etc/apache2/mods-available/deflate.conf, where it only enables compression for files with a MIME type of text/html, text/plain, and text/xml. Just in case you haven't found it already, the documentation here might help you find what you're looking for: http://httpd.apache.org/docs/2.0/mod/mod_deflate.html
OK, thank you, I will try to change the configuration. But why does it work correctly with http? Isn't the compression configuration the same for http and https?
Not necessarily, and in the case of your server it definitely isn't: % curl --compressed -k -I https://rom1v.com/shuttle-launch.ogg HTTP/1.1 200 OK Date: Fri, 12 Mar 2010 19:30:51 GMT Server: Apache Last-Modified: Thu, 11 Mar 2010 22:00:40 GMT ETag: "19b5e8d-4818d8baf1c4d" Accept-Ranges: bytes Vary: Accept-Encoding Content-Encoding: gzip Content-Type: audio/ogg % curl --compressed -k -I http://dl.rom1v.com/noindex/shuttle-launch.ogg HTTP/1.1 200 OK Date: Fri, 12 Mar 2010 19:31:12 GMT Server: Apache Last-Modified: Thu, 11 Mar 2010 22:00:40 GMT ETag: "709-19b5e8d-4818d8baf1c4d" Accept-Ranges: bytes Content-Length: 26959501 Content-Type: audio/ogg
Thanks for your help, I added this line in deflate.conf : SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png|ogg|oga|ogv)$ no-gzip dont-vary And it works.
