Hi Some days ago appear new problem with youtube. Each time konqueror try to play movie, message "Old Flash? Go upgrade!" is showed, and movie play is stopped. Of course I have newest flash player plugin (basic dig into yt code shows that 8.0 is enough tough). I have tested it on 3 computers with 2 different konq versions (4.4.2 and 4.3.5). Deeply analyzing of yt code is a horror, but hopefully someone did this before. Take a look here: https://rentzsch.lighthouseapp.com/projects/24342/tickets/517 It seems that yt fetch flash version by directly calling plugins public functions, which should be should be available trough js in DOM object of . Testcase form this page ( https://rentzsch.lighthouseapp.com/projects/24342/tickets/517/a/421263/yt- flash-version.html ) shows that konqueror didn't support this feature or it is buggy. Better this features are visible i.e. here (flash movie, javascript controller): http://www.permadi.com/tutorial/flashjscommand/ I should fill bug report in bugzilla, but I have no idea what part of KDE is a problem, khtml, kjs, nspluginviewer or all of them. I can investigate this little more, or even write some code, but I have no idea where I should start search appropriate code connected with this (nspluginviewr implementation of functions connected with this (NPN_Invoke ?); kjs and khtml object extra methods an properties) -- Konrad Rzepecki (Hannibal)
