| - | ======video-meta====== | ||
| - | |||
| - | ''Video-meta'' is a Perl script by Mike Schilli that displays attributes of a video file, helpful in "video forensics", when you need to know what codec and frame rate a video was shot in, quickly and easily. ''Video-meta'' invokes the ''Video::FrameGrab'' module, which in turn invokes **mplayer**. | ||
| - | |||
| - | Video-meta achieves the same results as the ''mediainfo'' tools (''mediainfo'' and **mediainfo-gui''), which are included in the default Slackermedia queue file, so strictly speaking this is doubling up on functionality. You may find it useful, however, since it gives //less// information than other tools, in an easy-to-read format, and tends to favour the most useful and common information rather than every last detail that 90% of the time you will not need. | ||

| - | ===== Install ===== | ||
| - | |||
| - | The installation is easy but unique in that it involves Perl, which has its own way of installing modules. It also depends upon ''perl-yaml'', available from [[http://slackBuilds.org]]. | ||
| - | |||
| - | Once you have yaml installed, install ''video::framegrab'' perl module with the command: | ||
| - | |||
| - | <code> | ||
| - | $ su -c "perl -MCPAN -e \ | ||
| - | 'install Video::FrameGrab'" | ||
| - | </code> | ||
| - | |||
| - | When that install process is over, install the ''data::dump'' perl module with the command: | ||
| - | |||
| - | <code> | ||
| - | $ su -c "perl -MCPAN -e \ | ||
| - | 'install Data::Dump'" | ||
| - | </code> | ||
| - | |||
| - | The script ''video-meta'' itself requires no installation, although the initial line of the script needs modifying so that the script can find Perl on the system: | ||
| - | |||
| - | <code> | ||
| - | $ wget ftp://linuxmagazin.de/pub/magazin/2010/01/Perl/video-meta \ | ||
| - | -O video-meta.pl | ||
| - | $ sed "1s#/local##" video-meta.pl > video-meta | ||
| - | $ chmod +x video-meta | ||
| - | $ su -c 'cp video-meta /usr/local/bin/' | ||
| - | </code> | ||
| - | |||
| - | ===== Usage ===== | ||
| - | |||
| - | Invoke ''video-meta'' before the name of a video file: | ||
| - | |||
| - | <code> | ||
| - | $ video-meta foo.avi | ||
| - | </code> | ||
| - | |||
| - | The metadata attributes associated with foo.avi are printed in your terminal. | ||
