Reworked some of the autoplay logic in LLViewerMediaImpl to try and make it more consistent when media is unloaded and reloaded by the performance manager.
LLViewerMediaImpl will now keep track of the media state and current time of media that it unloads for performance reasons, and attempt to restore playing or paused media to the same playhead time and state (playing or paused) when it reloads.
Added "done" status that time-based media plugins can use to indicate that they've reached the end of the media and stopped.
Added logging of priority transitions, for use in debugging issues with the peformance manager.
Added LLPluginClassMedia::getVolume().
Added setVolume/getVolumeupdateVolume methods to LLViewerMediaImpl.
LLViewerMedia::setVolume() now no longer overrides the volume settings on all media instances -- it now sets a "global volume" value which is multiplied by all instances' volumes to modulate them.
Cleaned up volume/mute handling in LLPanelMediaHUD (made it go through the LLViewerMediaImpl interface instead of directly through LLPluginClassMedia, and removed the mMediaVolume member variable, since the media impl now stores that state).
Implement name fetching capabilities for Webkit and Quicktime plugins
Adds support for new PluginAPI message (MEDIA_EVENT_NAME_CHANGED) that updates the "title" of the media. In WebKit plugin this is the contents of the <title> tag. In The QuickTime plugin it is the "display name" from the movie meta data
Made the "loaded_duration" parameter also implicitly set the progress percentage and send out MEDIA_EVENT_PROGRESS_UPDATED messages when it changes.
Made the quicktime plugin set the "loaded_duration" parameter in its update messages.
Made LLPluginProcessParent differentiate between failures launching/loading the plugin and failures after the plugin has been loaded. This allows us to handle launch failures differently, since retrying is unlikely to fix them.
Added new media event MEDIA_EVENT_PLUGIN_FAILED_LAUNCH to indicate a launch failure.
Added a case for the new event to LLViewerMediaImpl::handleMediaEvent() that sets the "failed init" flag to prevent retries.
svn merge -r 129913:131718 svn+ssh://svn.lindenlab.com/svn/linden/branches/pluginapi/pluginapi_05
Some branch shenannigans in the pluginapi_05 branch caused this to become a two-part merge.
