Here’s my latest update to dhyana.pl…

Change Log

Added a title to the output image, which can be in a different font and colour from the rest of the text.
Use Getopt to parse command line, and accept more options.
Improved handling of certain dodgy WMV files, mostly thanks to Matt Pinkham.
Improved use of FFMPEG
Code straightened out to use functions — it used to be one big long mess.
Added a help function — just run the program with the —help paramater.

Perl Getopt::ArgvFile
Perl Getopt::Long ≥ 2.33
Perl Pod::Usage;

18/11/2007: Dhyana.pl Updated

This release works around errors in capturing screen shots from certain WMV files. It also changes the default geometry from 240×180+0+0 to “auto” which is an automatically calculated, hopefully appropriate, geometry.

19/08/2007: Sequential Video Thumbnails on Linux

So, I was looking for a way to create sequential video thumbnails (like this one) from a video file on Linux. I found that my options were severely limited. On Windows there are a plethora of tools capable of this fairly simple task, including Media Player Classic, but on Linux all I could find was QFrameCatcher. The QFrameCatcher website was inaccessible yesterday; today I managed to download the source code, but couldn’t get it to build.

Anyway, I decided it probably wouldn’t be very difficult to build my own so…

dhyana.pl

dhyana.pl is a small Perl script that co-ordinates mplayer and ImageMagick to create a lovely montage of thumbnails. (Dyhana — roughly pronounced as “jahna” — is the Sanskrit word for a deep meditation.)
