* Add frame rate conversion when there is no audio channel. This makes
ffmpeg/ffserver work again when just capturing video from a live source and you are streaming feeds of different frame rates. * Fix a segfault in argument processing * Add handling for -vhook argument * Add logic to call video hooks if any have been specified. Originally committed as revision 1247 to svn://svn.ffmpeg.org/ffmpeg/trunk
