| - | ------------------------------------------------------------------------------- | ||
| - | |||
| - | Mike Schilli's perl script to show metadata on a video file is a helpful "video | ||
| - | forensics" tool that invokes the Video::FrameGrab module which in turn invokes | ||
| - | mplayer. This tool can quickly help a video artist determine codecs, frame | ||
| - | sizes, bitrates, frame rates and other properties of video clips at a glance. | ||
| - | The installation is easy but unique in that it involves perl, which has its own | ||
| - | way of installing modules. It also depends upon yaml, available from | ||
| - | SlackBuilds.org | ||
| - | |||
| - | 1. Install the video::framegrab perl module with the command: | ||
| - | |||
| - | $ su -c "perl -MCPAN -e | ||
| - | 'install Video::FrameGrab'" | ||
| - | |||
| - | |||
| - | 2. Install the data::dump perl module with the command: | ||
| - | |||
| - | $ su -c "perl -MCPAN -e | ||
| - | 'install Data::Dump'" | ||
| - | |||
| - | |||
| - | 3. 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. | ||
| - | |||
| - | $ 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/' | ||
| - | | ||
| - | |||
| - | |||
| - | The script can then be used by simply invoking it before the name of a video | ||
| - | file, such as: video-meta foo.avi, which will list all metadata attributes | ||
| - | associated with foo.avi | ||
| - | |||
| - | Mediainfo | ||
| - | |||
| - | Providing you with even more information about media is mediainfo and | ||
| - | mediainfo-gui. Obviously one works in the shell and one with a GUI. The amount | ||
| - | of useful information provided by mediainfo is unparalleled, and so it should | ||
| - | be on every multimedia artist's system. | ||
| - | |||
| - | Installation of mediainfo and its dependency libmediainfo can be done easily | ||
| - | through slackbuilds.org | ||
