* New stuff and bug fixes:
* Change to dynamically allocated buffers. Should reduce memory footprint significantly as well as eliminate a call to av_abort! * Better version of WMP rate switching infrastructure. Currently turned off till the PTS fixes are in. * Added a Redirect type feature. This allows URLs served by ffserver to just redirect to somewhere else. You might want to do this. Really this needs to be enhanced -- say to handle all 404 pages. * Add mechanism to automatically fire up ffmpeg on ffserver start. This is turned on by adding the Launch keyword to the <feed> definition. * Add logic to take care of non-wmp user agents requesting .asf files. They now get a [reference] file with an appropriate mime type. This fixes the mplayer problem. * Make sure that we have a large buffer for the stats page. * Add a FaviconURL keyword to the status stream definition. If set, then it generates the appropriate HTML so that IE and Mozilla will display the favicon as appropriate. OK -- this is a pretty random feature. * If the ffmpeg is running as a child of ffserver, then report it's CPU usage on the status page. [This is linux only -- maybe somebody could do the work for another OS. The tricky thing is getting the 'ps' command right.] Originally committed as revision 630 to svn://svn.ffmpeg.org/ffmpeg/trunk
