It is not intended to solve any particular problems, however you may find it useful. This php class * is in no way associated with the actual FFmpeg releases. Any mistakes contained in this php class are mine and mine * alone. * * Please Note: There are several prerequisites that are required before this class can be used as an aid to manipulate * video and audio. You must at the very least have FFMPEG compiled on your server. If you wish to use this class for FLV * manipulation you must compile FFMPEG with LAME and Ruby's FLVTOOL2. I cannot answer questions regarding the install of * the server binaries needed by this class. I had too learn the hard way and it isn't easy, however it is a good learning * experience. For those of you who do need help read the install.txt file supplied along side this class. It wasn't written * by me however I found it useful when installing ffmpeg for the first time. The original source for the install.txt file * is located http://www.luar.com.hk/blog/?p=669 and the author is Lunar. * * @see install.txt * * @uses ffmpeg http://ffmpeg.sourceforge.net/ * @uses lame http://lame.sourceforge.net/ * @uses flvtool2 http://www.inlet-media.de/flvtool2 (and ruby http://www.ruby-lang.org/en/) * * @config examples/example-config.php Please edit this files in order for the examples to work. * @example examples/example01.php Converts video to Flash Video (ie FLV). * @example examples/example02.php Screen grabs video frames. * @example examples/example03.php Compile a movie from multiple jpegs * @example examples/example04.php Watermark a video. * @example examples/example05.php Access media metadata without using the ffmpeg-php library. * @example examples/example06.php Extract audio from video. * @example examples/example07.php Join multiple videos together. * @example examples/example08.php Easy video conversion to common formats using the adapters. * @example examples/example09.php Shows you how to access the information about your ffmpeg installation. * @example examples/example10.php Shows you how to extract a specific frame from a movie. * @example examples/example11.php Shows you how to use the ffmpeg-php adapters to provide a pure php emulation of ffmpeg-php. * @example examples/example12.php Shows you how to manipulate/format timecode strings. * @example examples/example13.php This demonstrates how to simply create a FLV stream script. */ /** * Set the ffmpeg binary path */ if(!defined('PHPVIDEOTOOLKIT_FFMPEG_BINARY')) { define('PHPVIDEOTOOLKIT_FFMPEG_BINARY', '/usr/local/bin/ffmpeg'); } /** * Set the flvtool2 binary path */ if(!defined('PHPVIDEOTOOLKIT_FLVTOOLS_BINARY')) { define('PHPVIDEOTOOLKIT_FLVTOOLS_BINARY', '/usr/bin/flvtool2'); } /** * Set the watermark vhook path */ if(!defined('PHPVIDEOTOOLKIT_FFMPEG_WATERMARK_VHOOK')) { define('PHPVIDEOTOOLKIT_FFMPEG_WATERMARK_VHOOK', '/usr/local/lib/vhook/watermark.so'); } /** * Set the memcoder path */ if(!defined('PHPVIDEOTOOLKIT_MENCODER_BINARY')) { define('PHPVIDEOTOOLKIT_MENCODER_BINARY', '/usr/local/bin/mencoder'); } /** * Codec support constants */ define('PHPVIDEOTOOLKIT_ENCODE', 'encode'); define('PHPVIDEOTOOLKIT_DECODE', 'decode'); /** * Process Results from PHPVideoToolkit::execute */ // any return value with this means everything is ok define('PHPVIDEOTOOLKIT_RESULT_OK', true); // any return value with this means the file has been processed/converted ok however it was // not able to be written to the output address.
