For the uploading problem, after examining the apache error log for php errors, I found the following page with the appropriate patches and after applying it, upload of ogg / ogv files now works properly. http://www.mail-archive.com/mediawiki-cvs@lists.wikimedia.org/msg07933.html My new problem is with the Sequence part of the wiki, which has the following problem: A new sequence is created A video file is added to the sequence Attempting to switch to visual editor shows the visual editor window but does not produce any output, instead it shows for ever "Loading playlist...", "Loading timeline...", "Loading user rights..." Any suggestions on what to check are very welcome.

I am now able to add new streams and tag / transcribe them. My question though has to do with uploading new video content to the site. I have setup all the relevant variables for allowed extensions, file size uploads,etc. If I upload any type of allowed content (i.e. mp4 video, word document, jpeg image) the upload is completed and the new content is available. However, if I try to upload an ogg or ogv file, either directly or by transcoding it by fireogg plugin, the upload does not complete. No errors are produced in the web server or other system logs. Any suggestions on what to look for in order to resolve this ? My current way of uploading content is to copy the file to a folder on the web server and then use the add stream to create a stream and reference to the video file. Also, is there any batch upload / import method available? Regards Ioannis
