I am not able to upload large windows media video (wmv) files to a MediaWiki 1.5.5 running on php 4.3.10-16 and MySQL 4.0.24_Debian-10sarge1-log. In testing, I am able to upload small wmv files (<3meg). When I try with large ones, I either (a) the page waits for a few minutes (while status bar in IE slowly grows) and then appears to refresh with no error (and no file uploaded) or (b) IE shows "this page cannot be displayed' The uploads directory is writable. I can upload other images, mp3 files (tested successfully 10 meg), swf or fla flash files (tested >7megs) and these appear perfectly. I've tried increasing the php.ini settings: memory_limit = 16M; upload_max_filesize = 12M; post_max_size = 12M; I have also increased the time allowed for scripts to run and load. I added to LocalSettings.php: $wgFileExtensions = array('gif', .. The others already there. 'wmv'); $wgVerifyMimeType = false; When I look at a small wmv (<3meg) file I successfully uploaded, the mime type is text/plain (which seems odd, mp3 files are properly identified) Any ideas? Could it be the codec I used to encode the wmv file? (I used camtasia - this is for video based training in our internal company wiki). Thanks!
