Focused crawls are collections of frequently-updated webcrawl data from narrow (as opposed to broad or wide) web crawls, often focused on a single domain or subdomain.
FFmpegPHP is a pure OO PHP port of ffmpeg-php library that was written in C. It adds an easy to use, object-oriented API for accessing and retrieving information from video and audio files. It has methods for returning frames from movie files as images that can be manipulated using PHP's image functions. This works well for automatically creating thumbnail images from movies. FFmpegPHP is also useful for reporting the duration and bitrate of audio files (mp3, wma...). FFmpegPHP can access many of the video formats supported by ffmpeg (mov, avi, mpg, wmv...)
